- Use strict and warnings pragmas.
- If open() fails then show the reason.
- Set STDIN io layer :crlf so that input is properly read on Windows.
- When STDIN is used as input, the filename $f is now set to "STDIN".
Various error messages in single() use $f for the filename and this way
it is not undefined when STDIN.

- cmake: enable `BUILD_DOCS` by default (this controls converting and
installing `.3` files from `.md` sources)
- cmake: speed up generating `.3` files by using a single command per
directory, instead of a single command per file. This reduces external
commands by about a thousand. (There remains some CMake logic kicking
in resulting in 500 -one per file- external `-E touch_nocreate` calls.)
- cd2nroff: add ability to process multiple input files.
- cd2nroff: add `-k` option to use the source filename to form the
output filename. (instead of the default in-file `Title:` line.)

curldown is this new file format for libcurl man pages. It is markdown
inspired with differences:
- Each file has a set of leading headers with meta-data
- Supports a small subset of markdown
- Uses .md file extensions for editors/IDE/GitHub to treat them nicely
- Generates man pages very similar to the previous ones
- Generates man pages that still convert nicely to HTML on the website
- Detects and highlights mentions of curl symbols automatically (when
their man page section is specified)
tools:
- cd2nroff: converts from curldown to nroff man page
- nroff2cd: convert an (old) nroff man page to curldown
- cdall: convert many nroff pages to curldown versions
- cd2cd: verifies and updates a curldown to latest curldown
This setup generates .3 versions of all the curldown versions at build time.
CI:
Since the documentation is now technically markdown in the eyes of many
things, the CI runs many more tests and checks on this documentation,
including proselint, link checkers and tests that make sure we capitalize the
first letter after a period...

This clarifies the handling of server responses by folding the code for
the complicated protocols into their protocol handlers. This concerns
mainly HTTP and its bastard sibling RTSP.
The terms "read" and "write" are often used without clear context if
they refer to the connect or the client/application side of a
transfer. This PR uses "read/write" for operations on the client side
and "send/receive" for the connection, e.g. server side. If this is
considered useful, we can revisit renaming of further methods in another
PR.
Curl's protocol handler `readwrite()` method been changed:
```diff
- CURLcode (*readwrite)(struct Curl_easy *data, struct connectdata *conn,
- const char *buf, size_t blen,
- size_t *pconsumed, bool *readmore);
+ CURLcode (*write_resp)(struct Curl_easy *data, const char *buf, size_t blen,
+ bool is_eos, bool *done);
```
The name was changed to clarify that this writes reponse data to the
client side. The parameter changes are:
* `conn` removed as it always operates on `data->conn`
* `pconsumed` removed as the method needs to handle all data on success
* `readmore` removed as no longer necessary
* `is_eos` as indicator that this is the last call for the transfer
response (end-of-stream).
* `done` TRUE on return iff the transfer response is to be treated as
finished
This change affects many files only because of updated comments in
handlers that provide no implementation. The real change is that the
HTTP protocol handlers now provide an implementation.
The HTTP protocol handlers `write_resp()` implementation will get passed
**all** raw data of a server response for the transfer. The HTTP/1.x
formatted status and headers, as well as the undecoded response
body. `Curl_http_write_resp_hds()` is used internally to parse the
response headers and pass them on. This method is public as the RTSP
protocol handler also uses it.
HTTP/1.1 "chunked" transport encoding is now part of the general
*content encoding* writer stack, just like other encodings. A new flag
`CLIENTWRITE_EOS` was added for the last client write. This allows
writers to verify that they are in a valid end state. The chunked
decoder will check if it indeed has seen the last chunk.
The general response handling in `transfer.c:466` happens in function
`readwrite_data()`. This mainly operates now like:
```
static CURLcode readwrite_data(data, ...)
{
do {
Curl_xfer_recv_resp(data, buf)
...
Curl_xfer_write_resp(data, buf)
...
} while(interested);
...
}
```
All the response data handling is implemented in
`Curl_xfer_write_resp()`. It calls the protocol handler's `write_resp()`
implementation if available, or does the default behaviour.
All raw response data needs to pass through this function. Which also
means that anyone in possession of such data may call
`Curl_xfer_write_resp()`.
Closes#12480
Windows compilers define `_WIN32` automatically. Windows SDK headers
or build env defines `WIN32`, or we have to take care of it. The
agreement seems to be that `_WIN32` is the preferred practice here.
Make the source code rely on that to detect we're building for Windows.
Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for
Windows detection, next to the official `_WIN32`. After this patch it
only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`.
There is a slight chance these break compatibility with Windows
compilers that fail to define `_WIN32`. I'm not aware of any obsolete
or modern compiler affected, but in case there is one, one possible
solution is to define this macro manually.
grepping for `WIN32` remains useful to discover Windows-specific code.
Also:
- extend `checksrc` to ensure we're not using `WIN32` anymore.
- apply minor formatting here and there.
- delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

This tool generates a scheme-matching table.
It iterates over a number of different initial and shift values in order
to find the hash algorithm that needs the smallest possible table.
The generated hash function, table and table size then needs to be used
by the url.c:Curl_getn_scheme_handler() function.
We use `stdint.h` unconditionally in all places except one. These uses
are imposed by external dependencies / features. nghttp2, quic, wolfSSL
and `HAVE_MACH_ABSOLUTE_TIME` do require this C99 header. It means that
any of these features make curl require a C99 compiler. (In case of
MSVC, this means Visual Studio 2010 or newer.)
This patch changes the single use of `stdint.h` guarded by
`HAVE_STDINT_H` to use `stdint.h` unconditionally. Also stop using
`inttypes.h` as an alternative there. `HAVE_INTTYPES_H` wasn't used
anywhere else, allowing to delete this feature check as well.

Uses scripts/cmp-config.pl two compare two curl_config.h files,

The script also shows the matches that were *not* used. Possibly
subjects for removal.

Earlier this year we changed our own stderr variable to use the standard
name `stderr` (to avoid bugs where someone is using `stderr` instead of
the curl-tool specific variable). This solution needed to override the
standard `stderr` symbol via the preprocessor. This in turn didn't play
well with unity builds and caused curl tool to crash or stay silent due
to an uninitialized stderr. This was a hard to find issue, fixed by
manually breaking out one file from the unity sources.
To avoid two these two tricks, this patch implements a different
solution: Restore using our own local variable for our stderr output and
leave `stderr` as-is. To avoid using `stderr` by mistake, add a
`checksrc` rule (based on logic we already used in lib for `strerror`)
that detects any `stderr` use in `src` and points to using our own
variable instead: `tool_stderr`.

EGD is Entropy Gathering Daemon, a socket-based entropy source supported
by pre-OpenSSL v1.1 versions and now deprecated. curl also deprecated it
a while ago.

Delete detection from both cmake and autotools, along with the related

Originally these scripts filtered out names that have no space so that
they better avoid nick names not intended for credits. Such names are
not too commonly used, plus we now give credit even to those.
Additionally: non-latin names, like Asian, don't have spaces at all so
they were also filtered out and had to be manually added which made it
an error-prone operation where Asian names eventually easily fell off by
mistake.

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)

The open paren check wants to warn for spaces before open parenthesis
for if/while/for but also for any function call. In order to avoid
catching function pointer declarations, the logic allows a space if the
first character after the open parenthesis is an asterisk.
I also spotted what we did not include "switch" in the check but we should.
This check is a little lame, but we reduce this problem by not allowing
that space for if/while/for/switch.
