urldata: move async resolver state from easy handle to connectdata
- resolving is done for a connection, not for every transfer
- save create/dup/free of a cares channel for each transfer
- check values of setopt calls against a local channel if no
  connection has been attached yet, when needed.

lib: disambiguate Curl_client_write flag semantics
- use CLIENTWRITE_BODY *only* when data is actually body data
- add CLIENTWRITE_INFO for meta data that is *not* a HEADER
- debug assertions that BODY/INFO/HEADER is not used mixed
- move `data->set.include_header` check into Curl_client_write
  so protocol handlers no longer have to care
- add special in FTP for `data->set.include_header` for historic,
  backward compatible reasons
- move unpausing of client writes from easy.c to sendf.c, so that
  code is in one place and can forward flags correctly

hostip.c: Move macOS-specific calls into global init call
https://github.com/curl/curl/pull/7121 introduced a macOS system call
to `SCDynamicStoreCopyProxies`, which is invoked every time an IP
address needs to be resolved.

However, this system call is not thread-safe, and macOS will kill the
process if the system call is run first in a fork. To make it possible
for the parent process to call this once and prevent the crash, only
invoke this system call in the global initialization routine.

In addition, this change is beneficial because it:

1. Avoids extra macOS system calls for every IP lookup.
2. Consolidates macOS-specific initialization in a separate file.

lib: add CURLINFO_CONN_ID and CURLINFO_XFER_ID
- add an `id` long to Curl_easy, -1 on init
- once added to a multi (or its own multi), it gets
  a non-negative number assigned by the connection cache
- `id` is unique among all transfers using the same
  cache until reaching LONG_MAX where it will wrap
  around. So, not unique eternally.
- CURLINFO_CONN_ID returns the connection id attached to
  data or, if none present, data->state.lastconnect_id
- variables and type declared in tool for write out

cmake: add support for "unity" builds
Aka "jumbo" or "amalgamation" builds. It means to compile all sources
per target as a single C source. This is experimental.

You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake.
It requires CMake 3.16 or newer.

It makes builds (much) faster, allows for better optimizations and tends
to promote less ambiguous code.

Also add a new AppVeyor CI job and convert an existing one to use
"unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job.

Fix related issues:
- add missing include guard to `easy_lock.h`.
- rename static variables and functions (and a macro) with names reused
  across sources, or shadowed by local variables.
- add an `#undef` after use.
- add a missing `#undef` before use.
- move internal definitions from `ftp.h` to `ftp.c`.
- `curl_memory.h` fixes to make it work when included repeatedly.
- stop building/linking curlx bits twice for a static-mode curl tool.
  These caused doubly defined symbols in unity builds.
- silence missing extern declarations compiler warning for ` _CRT_glob`.
- fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`.
- fix colliding static symbols in debug mode: `debugtime()` and
  `statename`.
- rename `ssl_backend_data` structure to unique names for each
  TLS-backend, along with the `ssl_connect_data` struct member
  referencing them. This required adding casts for each access.
- add workaround for missing `[P]UNICODE_STRING` types in certain Windows
  builds when compiling `lib/ldap.c`. To support "unity" builds, we had
  to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows
  `schannel.h` option) _globally_. This caused an indirect inclusion of
  Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled
  as well. This requires `[P]UNICODE_STRING` types, which is apperantly
  not defined automatically (as seen with both MSVS and mingw-w64).
  This patch includes `<subauth.h>` to fix it.

- tweak unity builds to compile `lib/memdebug.c` separately in memory
  trace builds to avoid PP confusion.
- force-disable unity for test programs.
- do not compile and link libcurl sources to libtests _twice_ when libcurl
  is built in static mode.

KNOWN ISSUES:
- running tests with unity builds may fail in cases.
- some build configurations/env may not compile in unity mode. E.g.:

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)

lib: connect/h2/h3 refactor
Refactoring of connection setup and happy eyeballing. Move
nghttp2. ngtcp2, quiche and msh3 into connection filters.

 - eyeballing cfilter that uses sub-filters for performing parallel connects
 - socket cfilter for all transport types, including QUIC
 - QUIC implementations in cfilter, can now participate in eyeballing
 - connection setup is more dynamic in order to adapt to what filter did
   really connect.  Relevant to see if a SSL filter needs to be added or
   if SSL has already been provided
 - HTTP/3 test cases similar to HTTP/2
 - multiuse of parallel transfers for HTTP/3, tested for ngtcp2 and quiche

 - Fix for data attach/detach in VTLS filters that could lead to crashes
   during parallel transfers.
 - Eliminating setup() methods in cfilters, no longer needed.
 - Improving Curl_conn_is_alive() to replace Curl_connalive() and
   integrated ssl alive checks into cfilter.
 - Adding CF_CNTRL_CONN_INFO_UPDATE to tell filters to update
   connection into and persist it at the easy handle.

 - Several more cfilter related cleanups and moves:
   - stream_weigth and dependency info is now wrapped in struct
     Curl_data_priority
   - Curl_data_priority members depend is available in HTTP2|HTTP3
   - Curl_data_priority members depend on NGHTTP2 support
   - handling init/reset/cleanup of priority part of url.c
   - data->state.priority same struct, but shallow copy for compares only

 - PROTOPT_STREAM has been removed
   - Curl_conn_is_mulitplex() now available to check on capability

 - Adding query method to connection filters.
   - ngtcp2+quiche: implementing query for max concurrent transfers.

 - Adding is_alive and keep_alive cfilter methods. Adding DATA_SETUP event.
   - setting keepalive timestamp on connect
   - DATA_SETUP is called after the connection has been completely
     setup (but may not connected yet) to allow filters to initialize
     data members they use.

 - there is no socket to be had with msh3, it is unclear how select
   shall work

 - manual test via "curl --http3 https://curl.se" fail with "empty
   reply from server".

 - Various socket/conn related cleanups:
   - Curl_socket is now Curl_socket_open and in cf-socket.c
   - Curl_closesocket is now Curl_socket_close and in cf-socket.c
   - Curl_ssl_use has been replaced with Cur_conn_is_ssl
   - Curl_conn_tcp_accepted_set has been split into
     Curl_conn_tcp_listen_set and Curl_conn_tcp_accepted_set
     with a clearer purpose

mime: relax easy/mime structures binding
Deprecation and removal of codeset conversion support from the library
have released the strict need for an early binding of mime structures to
an easy handle (https://github.com/curl/curl/commit/2610142).

This constraint currently forces to create the handle before the mime
structure and the latter cannot be attached to another handle once
created (see https://curl.se/mail/lib-2022-08/0027.html).

This commit removes the handle pointers from the mime structures
allowing more flexibility on their use.

When an easy handle is duplicated, bound mime structures must however
still be duplicated too as their components hold send-time dynamic
information.

websockets: remodeled API to support 63 bit frame sizes
curl_ws_recv() now receives data to fill up the provided buffer, but can
return a partial fragment. The function now also get a pointer to a
curl_ws_frame struct with metadata that also mentions the offset and
total size of the fragment (of which you might be receiving a smaller
piece). This way, large incoming fragments will be "streamed" to the
application. When the curl_ws_frame struct field 'bytesleft' is 0, the
final fragment piece has been delivered.

curl_ws_recv() was also adjusted to work with a buffer size smaller than
the fragment size. (Possibly needless to say as the fragment size can
now be 63 bit large).

curl_ws_send() now supports sending a piece of a fragment, in a
streaming manner, in addition to sending the entire fragment in a single
call if it is small enough. To send a huge fragment, curl_ws_send() can
be used to send it in many small calls by first telling libcurl about
the total expected fragment size, and then send the payload in N number
of separate invokes and libcurl will stream those over the wire.

The struct curl_ws_meta() returns is now called 'curl_ws_frame' and it
has been extended with two new fields: *offset* and *bytesleft*. To help
describe the passed on data chunk when a fragment is delivered in many
smaller pieces.

The documentation has been updated accordingly.
