checksrc: disallow spaces before labels
Out of 415 labels throughout the code base, 86 of those labels were
not at the start of the line. Which means labels always at the start of
the line is the favoured style overall with 329 instances.

Out of the 86 labels not at the start of the line:
* 75 were indented with the same indentation level of the following line
* 8 were indented with exactly one space
* 2 were indented with one fewer indentation level then the following
  line
* 1 was indented with the indentation level of the following line minus
  three space (probably unintentional)

connections: introduce http/3 happy eyeballs
New cfilter HTTP-CONNECT for h3/h2/http1.1 eyeballing.
- filter is installed when `--http3` in the tool is used (or
  the equivalent CURLOPT_ done in the library)
- starts a QUIC/HTTP/3 connect right away. Should that not
  succeed after 100ms (subject to change), a parallel attempt
  is started for HTTP/2 and HTTP/1.1 via TCP
- both attempts are subject to IPv6/IPv4 eyeballing, same
  as happens for other connections
- tie timeout to the ip-version HAPPY_EYEBALLS_TIMEOUT
- use a `soft` timeout at half the value. When the soft timeout
  expires, the HTTPS-CONNECT filter checks if the QUIC filter
  has received any data from the server. If not, it will start
  the HTTP/2 attempt.

HTTP/3(ngtcp2) improvements.
- setting call_data in all cfilter calls similar to http/2 and vtls filters
  for use in callback where no stream data is available.
- returning CURLE_PARTIAL_FILE for prematurely terminated transfers
- enabling pytest test_05 for h3
- shifting functionality to "connect" UDP sockets from ngtcp2
  implementation into the udp socket cfilter. Because unconnected
  UDP sockets are weird. For example they error when adding to a
  pollset.

HTTP/3(quiche) improvements.
- fixed upload bug in quiche implementation, now passes 251 and pytest
- error codes on stream RESET
- improved debug logs
- handling of DRAIN during connect
- limiting pending event queue

HTTP/2 cfilter improvements.
- use LOG_CF macros for dynamic logging in debug build
- fix CURLcode on RST streams to be CURLE_PARTIAL_FILE
- enable pytest test_05 for h2
- fix upload pytests and improve parallel transfer performance.

GOAWAY handling for ngtcp2/quiche
- during connect, when the remote server refuses to accept new connections
  and closes immediately (so the local conn goes into DRAIN phase), the
  connection is torn down and a another attempt is made after a short grace
  period.
  This is the behaviour observed with nghttpx when we tell it to  shut
  down gracefully. Tested in pytest test_03_02.

TLS improvements
- ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, replaces
  copy of logic in all tls backends.
- standardized the infof logging of offered ALPNs
- ALPN negotiated: have common function for all backends that sets alpn proprty
  and connection related things based on the negotiated protocol (or lack thereof).

- new tests/tests-httpd/scorecard.py for testing h3/h2 protocol implementation.
  Invoke:
    python3 tests/tests-httpd/scorecard.py --help
  for usage.

Improvements on gathering connect statistics and socket access.
- new CF_CTRL_CONN_REPORT_STATS cfilter control for having cfilters
  report connection statistics. This is triggered when the connection
  has completely connected.
- new void Curl_pgrsTimeWas(..) method to report a timer update with
  a timestamp of when it happend. This allows for updating timers
  "later", e.g. a connect statistic after full connectivity has been
  reached.
- in case of HTTP eyeballing, the previous changes will update
  statistics only from the filter chain that "won" the eyeballing.
- new cfilter query CF_QUERY_SOCKET for retrieving the socket used
  by a filter chain.
  Added methods Curl_conn_cf_get_socket() and Curl_conn_get_socket()
  for convenient use of this query.
- Change VTLS backend to query their sub-filters for the socket when
  checks during the handshake are made.

HTTP/3 documentation on how https eyeballing works.

TLS improvements
- ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, replaces
  copy of logic in all tls backends.
- standardized the infof logging of offered ALPNs
- ALPN negotiated: have common function for all backends that sets alpn proprty
  and connection related things based on the negotiated protocol (or lack thereof).

Scorecard with Caddy.
- configure can be run with `--with-test-caddy=path` to specify which caddy to use for testing
- tests/tests-httpd/scorecard.py now measures download speeds with caddy

pytest improvements
- adding Makfile to clean gen dir
- adding nghttpx rundir creation on start
- checking httpd version 2.4.55 for test_05 cases where it is needed. Skipping with message if too old.
- catch exception when checking for caddy existance on system.

Makefile.mk: portable Makefile.m32
Update bare GNU Make `Makefile.m32` to:

- Move objects into a subdirectory.
- Add support for MS-DOS. Tested with DJGPP.
- Add support for Watt-32 (on MS-DOS).
- Add support for AmigaOS.
- Rename `Makefile.m32` to `Makefile.mk`
- Replace `ARCH` with `TRIPLET`.
- Build `tool_hugehelp.c` proper (when tools are available).
- Drop MS-DOS compatibility macro `USE_ZLIB` (replaced by `HAVE_LIBZ`)
- Add support for `ZLIB_LIBS` to override `-lz`.
- Omit object files when building examples.
- Default `CC` to `gcc` once again, for convenience. (Caveat: compiler
  name `cc` cannot be set now.)
- Set `-DCURL_NO_OLDIES` for examples, like autotools does.
- Delete `makefile.dj` files. Notice the configuration details and
  defaults are not retained with the new method.
- Delete `makefile.amiga` files. A successful build needs a few custom
  options. We're also not retaining all build details from the existing
  Amiga make files.
- Rename `Makefile.m32` to `Makefile.mk` to reflect that they are not
  Windows/MinGW32-specific anymore.
- Add support for new `CFG` options: `-map`, `-debug`, `-trackmem`
- Set `-DNDEBUG` by default.
- Allow using `-DOS=...` in all `lib/config-*.h` headers, syncing this
  with `config-win32.h`.
- Look for zlib parts in `ZLIB_PATH/include` and `ZLIB_PATH/lib`
  instead of bare `ZLIB_PATH`.

Note that existing build configurations for MS-DOS and AmigaOS likely
become incompatible with this change.

Example AmigaOS configuration:
```
export CROSSPREFIX=/opt/amiga/bin/m68k-amigaos-
export CC=gcc
export CPPFLAGS='-DHAVE_PROTO_BSDSOCKET_H'
export CFLAGS='-mcrt=clib2'
export LDFLAGS="${CFLAGS}"
export LIBS='-lnet -lm'
make -C lib -f Makefile.mk
make -C src -f Makefile.mk
```

Example MS-DOS configuration:
```
export CROSSPREFIX=/opt/djgpp/bin/i586-pc-msdosdjgpp-
export WATT_PATH=/opt/djgpp/net/watt
export ZLIB_PATH=/opt/djgpp
export OPENSSL_PATH=/opt/djgpp
export OPENSSL_LIBS='-lssl -lcrypt'
export CFG=-zlib-ssl
make -C lib -f Makefile.mk
make -C src -f Makefile.mk

lib: feature deprecation warnings in gcc >= 4.3
Add a deprecated attribute to functions and enum values that should not
be used anymore.
This uses a gcc 4.3 dialect, thus is only available for this version of
gcc and newer. Note that the _Pragma() keyword is introduced by C99, but
is available as part of the gcc dialect even when compiling in C89 mode.

It is still possible to disable deprecation at a calling module compile
time by defining CURL_DISABLE_DEPRECATION.

Gcc type checking macros are made aware of possible deprecations.

Some testing support Perl programs are adapted to the extended
declaration syntax.

Several test and unit test C programs intentionally use deprecated
functions/options and are annotated to not generate a warning.

New test 1222 checks the deprecation status in doc and header files.

Makefile.m32: deduplicate build rules [ci skip]
After this patch, we reduce the three copies of most `Makefile.m32`
logic to one. This now resides in `lib/Makefile.m32`. It makes future
updates easier, the code shorter, with a small amount of added
complexity.

`Makefile.m32` reduction:

|                   |  bytes | LOC total |  blank |  comment |  code |
|-------------------|-------:|----------:|-------:|---------:|------:|
| 7.85.0            |  34772 |      1337 |     79 |      192 |  1066 |
| before this patch |  17601 |       625 |     62 |      106 |   457 |
| after this patch  |  11680 |       392 |     52 |      104 |   236 |

Details:

- Change rules to create objects for the `v*` subdirs in the `lib` dir.
  This allows to use a shared compile rule and assumes that filenames
  are not (and will not be) colliding across these directories.
  `Makefile.m32` now also stores a list of these subdirs. They are
  changing rarely though.

- Sync as much as possible between the three `Makefile.m32` scripts'
  rules and their source/target sections.

- After this patch `CPPFLAGS` are all applied to the `src` sources once
  again. This matches the behaviour of cmake/autotools. Only zlib ones
  are actually required there.

- Use `.rc` names from `Makefile.inc` instead of keeping a duplicate.

- Change examples to link `libcurl.dll` by default. This makes building
  trivial, even as a cross-build:
    `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32`
  To run them, you need to move/copy or add-to-path `libcurl.dll`.
  You can select static mode via `CFG=-static`.

- List more of the `Makefile.m32` config variables.

- Drop `.rc` support from examples. It made it fragile without much
  benefit.

- Include a necessary system lib for the `externalsocket.c` example.

- Exclude unnecessary systems libs when building in `-dyn` mode.

Makefile.m32: major rework [ci skip]
This patch overhauls `Makefile.m32` scripts, fixing a list of quirks,
making its behaviour and customization envvars align better with other
build systems, aiming for less code, that is easier to read, use and
maintain.

Details:
- Rename customization envvars:
  `CURL_CC` -> `CC`
  `CURL_RC` -> `RC`
  `CURL_AR` -> `AR`
  `CURL_LDFLAG_EXTRAS_DLL` -> `CURL_LDFLAGS_LIB`
  `CURL_LDFLAG_EXTRAS_EXE` -> `CURL_LDFLAGS_BIN`
- Drop `CURL_STRIP` and `CURL_RANLIB`. These tools are no longer used.
- Accept `CFLAGS`, `CPPFLAGS`, `RCFLAGS`, `LDFLAGS` and `LIBS` envvars.
- Drop `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, `CURL_RCFLAG_EXTRAS` in
  favor of the above.
- Do not automatically enable `zlib` with `libssh2`. `zlib` is optional
  with `libssh2`.
- Omit unnecessary `CPPFLAGS` options when building `curl.exe` and
  examples.
- Drop support for deprecated `-winssl` `CFG` option. Use `-schannel`
  instead.
- Avoid late evaluation where not necessary (`=` -> `:=`).
- Drop support for `CURL_DLL_A_SUFFIX` to override the implib suffix.
  Instead, use the standard naming scheme by default: `libcurl.dll.a`.
  The toolchain recognizes the name, and selects it automatically when
  asking for a `-shared` vs. `-static` build.
- Stop applying `strip` to `libcurl.a`. Follow-up from
  16a58e9f93. There was no debug info to
  strip since then.
- Stop setting `-O3`, `-W`, `-Wall` options. You can add these to
  `CFLAGS` as desired.
- Always enable `-DCURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG` with OpenSSL,
  to avoid that vulnerability on Windows.
- Add `-lbrotlicommon` to `LIBS` when using `brotli`.
- Do not enable `-nghttp3` without `-ngtcp2`.
- `-ssh2` and `-rtmp` options no longer try to auto-select a TLS-backend.
  You need to set the backend explicitly. This scales better and avoids
  issues with certain combinations (e.g. `libssh2` + `wolfssl` with no
  `schannel`).
- Default to OpenSSL TLS-backend with `ngtcp2`. Possible to override via
  `NGTCP2_LIBS`.
- Old, alternate method of enabling components (e.g. `SSH2=1`) no longer
  supported.
- Delete `SPNEGO` references. They were no-ops.
- Drop support for Win9x environments.
- Allow setting `OPENSSL_LIBS` independently from `OPENSSL_LIBPATH`.
- Support autotools/CMake `libssh2` builds by default.
- Respect `CURL_DLL_SUFFIX` in `-dyn` mode when building `curl.exe` and
  examples.
- Assume standard directory layout with `LIBCARES_PATH`. (Instead of the
  long gone embedded one.)
- Stop static linking with c-ares by default. Add
  `CPPFLAGS=-DCARES_STATICLIB` to enable it.
- Reorganize internal layout to avoid redundancy and emit clean diffs
  between src/lib and example make files.
- Delete unused variables.
- Code cleanups/rework.
- Comment and indentation fixes.

Makefile.m32: delete legacy component bits [ci skip]
- Drop auto-detection of OpenSSL 1.0.2 and earlier. Now always defaulting
  to OpenSSL 1.1.0 and later, LibreSSL and BoringSSL.

- Drop `Invalid path to OpenSSL package` detection. OpenSSL has been
  using a standard file layout since 1.1.0, so this seems unnecessary
  now.

- Drop special logic to enable Novell LDAP SDK support.

- Drop special logic to enable OpenLDAP LDAP SDK support. This seems
  to be distinct from native OpenLDAP, with support implemented inside
  `lib/ldap.c` (vs. `lib/openldap.c`) back when the latter did not exist
  yet in curl.

- Add `-lwldap32` only if there is no other LDAP library (either native
  OpenLDAP, or SDKs above) present.

- Update `doc/INSTALL.md` accordingly.

After this patch, it's necessary to make configration changes when using
OpenSSL 1.0.2 or earlier, or the two LDAP SDKs.

OpenSSL 1.0.2 and earlier:
```
export OPENSSL_INCLUDE = <path-to-openssl>/outinc
export OPENSSL_LIBPATH = <path-to-openssl>/out
export OPENSSL_LIBS = -lssl32 -leay32 -lgdi32
```

Novell LDAP SDK, previously enabled via `USE_LDAP_NOVELL=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/inc -DCURL_HAS_NOVELL_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib/mscvc -lldapsdk -lldapssl -lldapx
```

OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib -lldap -llber
```

I haven't tested these scenarios, and in general we recommend using
a recent OpenSSL release. Also, WinLDAP (the Windows default) and
OpenLDAP (via `-DUSE_OPENLDAP`) are the LDAP options actively worked on
in curl.

- Delete broken link and reference to the pre-Vista WinIDN add-on.
  MS no longer distribute it.
- Delete related `WINIDN_PATH` option. IDN is a system lib since Vista.
- Sync `LIBCARES_PATH` default with the rest of dependencies.
- Delete version numbers from dependency path defaults.
- `libgsasl` package is now called `gsasl`.
- Delete `libexpat` and `libxml2` references. No longer used by curl.
- Delete `Edit the path below...` comments. We recommend to predefine
  those envvars instead.
- `libcares.a` is not an internal dependency anymore. Stop using it as
  such.
- `windres` `--include-dir` -> `-I`, `-F` -> `--target=` for readability.
- Delete `STRIP`, `CURL_STRIP`, `AR` references from `src/Makefile.m32`.
  They were never used.
- Stop to `clean` some objects twice in `src/Makefile.m32`.
- Delete cvs-specific leftovers.
- Finish resource support in examples make file.
- Delete `-I<root>/lib` from examples make file.
- Fix copyright start year in examples make file.
- Delete duplicate `ftpuploadresume` input in examples make file.
- Sync OpenSSL lib order, `SYNC` support, `PROOT` use, dependency path
  defaults, variables names and other internal bits between the three
  make files.
- `lib/Makefile.m32` accepted custom options via `DLL_LIBS` envvar. This
  was lib-specific and possibly accidental. Use `CURL_LDFLAG_EXTRAS_DLL`
  envvar for the same effect.
- Fix linking `curl.exe` and examples to wrong static libs with
  auto-detected OpenSSL 1.0.2 or earlier.
- Add `-lgdi32` for OpenSSL 1.0.2 and earlier only.
- Add link to Novell LDAP SDK and use a relative default path. Latest
  version is from 2016, linked to an outdated OpenSSL 1.0.1.
- Whitespace and comment cleanups.

TODO in a next commit:

Delete built-in detection/logic for OpenSSL 1.0.2 and earlier, the Novell
LDAP SDK and the other LDAP SDK (which is _not_ OpenLDAP). Write up the
necessary custom envvars to configure them.

examples/curlx.c: remove
This example is a bit convoluted to use as an example, combined with the
special license for it makes it unsuitable.

Makefile.m32: allow -nghttp3/-ngtcp2 without -ssl [ci skip]
Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl`
was also enabled. `-ssl` meaning OpenSSL (and its forks). After
8a13be227e nghttp3/ngtcp2 can also be
used together with wolfSSL. This patch adds the ability to enable
`-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to
use it with wolfSSL or other, future TLS backends.

Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2`
unconditionally. After this patch, this is no longer the case, and now
it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only
together with a compatible TLS backend.

When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2
library must be configured manually, e.g.:
  `export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl`

(or via `NGTCP2_LIBS`)

Makefile.m32: add CURL_RC and CURL_STRIP variables [ci skip]
They allow to override the hardcoded values for the `windres` and `strip`
tools, complementing the existing set of `CURL_{CC,AR,RANLIB}` variables.

`CURL_RC` comes handy when using LLVM tools with `CROSSPREFIX=llvm-` and
`CURL_CC=clang` set on current latest debian:unstable or earlier, where
`llvm-windres` is missing, and a `CURL_RC=<triplet>-windres` fixes it.
Hopefully this will be fixed in the llvm package. FWIW `llvm-windres`
does exist in Homebrew llvm, MSYS2 llvm and llvm-mingw.

CURLOPT_SERVER_RESPONSE_TIMEOUT: the new name
Starting now, CURLOPT_FTP_RESPONSE_TIMEOUT is the alias instead of the
other way around.

Since 7.20.0, CURLOPT_SERVER_RESPONSE_TIMEOUT has existed as an alias
but since the option is for more protocols than FTP the more "correct"
version of the option is the "server" one so now we switch.

makefile.m32: add support for custom ARCH [ci skip]
When building curl for target platform other than x64 and x86, it is now
possible to pass `ARCH=custom`, that will omit all hardcoded logic for
setting up CFLAGS/LDFLAGS/RCFLAGS for these platforms, and let these be
customized via `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, and a newly
added one for the resource compiler: `CURL_RCFLAG_EXTRAS`.

This makes it possible to use `makefile.m32` to build for ARM64 for
example.

windows: improve random source
- Use the Windows API to seed the fallback random generator.

  This ensures to always have a random seed, even when libcurl is built
  with a vtls backend lacking a random generator API, such as rustls
  (experimental), GSKit and certain mbedTLS builds, or, when libcurl is
  built without a TLS backend. We reuse the Windows-specific random
  function from the Schannel backend.

- Implement support for `BCryptGenRandom()` [1] on Windows, as a
  replacement for the deprecated `CryptGenRandom()` [2] function.

  It is used as the secure random generator for Schannel, and also to
  provide entropy for libcurl's fallback random generator. The new
  function is supported on Vista and newer via its `bcrypt.dll`. It is
  used automatically when building for supported versions. It also works
  in UWP apps (the old function did not).

- Clear entropy buffer before calling the Windows random generator.

  This avoids using arbitrary application memory as entropy (with
  `CryptGenRandom()`) and makes sure to return in a predictable state
  when an API call fails.

Makefile.m32: stop forcing XP target with ipv6 enabled [ci skip]
Since this [1] commit in 2011, `_WIN32_WINNT` was set fixed to Windows
XP when the `-ipv6` option is selected. Maybe this was added to support
pre-XP Windows versions (?). These days libcurl builds fine for both XP
and post-XP versions with IPv6 support enabled. The relevance of pre-XP
version is also low by now. Other build methods also do not impose such
limitation for a similar configuration. So, drop this hard-wired
`_WIN32_WINNT` limit from `Makefile.m32`, thus building for the default
Windows version set by the compiler. This is Vista for recent MinGW
versions.

Old behaviour can be restored by setting this envvar:
export CURL_CFLAG_EXTRAS=-D_WIN32_WINNT=0x0501

Makefile.m32: delete obsolete options, improve -On [ci skip]
- `-D_AMD64_` has not been necessary for mingw-w64 builds for a long time now.
- `-fno-strict-aliasing` is mentioned for Intel C compiler in autotools, and
  I used this with VxWorks in another project, but otherwise this isn't
  necessary anymore as a default. If a target still needs it, it can be
  added with `CURL_CFLAG_EXTRAS=-fno-strict-aliasing`
- bump up default optimization level to `-O3` (from `-O2`), and also rearrange
  option order so the default can now be overridden via
  `CURL_CFLAG_EXTRAS`.
- delete `-g` (generate debug info) from `CFLAGS` and `-s` from `LDFLAGS`
  (strip debug info). They were working against each other. Now, if someone
  needs debug info, it can be enabled via `CURL_CFLAG_EXTRAS=-g`
