After this patch, the codebase no longer overrides system printf
functions. Instead it explicitly calls either the curl printf functions
`curl_m*printf()` or the system ones using their original names.
Also:
- drop unused `curl_printf.h` includes.
- checksrc: ban system printf functions, allow where necessary.

The implementation was incomplete and lesser than the other backends. No
one ever reported a bug or requested enhancements for this, indicating
that this backend was never used.
Closes#18700
Before this patch `accept4()`, `socket()`, `socketpair()`, `send()` and
`recv()` system symbols were remapped via macros, using the same name,
to local curl debug wrappers. This patch replaces these overrides by
introducing curl-namespaced macros that map either to the system symbols
or to their curl debug wrappers in `CURLDEBUG` (TrackMemory) builds.
This follows a patch that implemented the same for `accept()`.
The old method required tricks to make these redefines work in unity
builds, and avoid them interfering with system headers. These tricks
did not work for system symbols implemented as macros.
The new method allows to setup these mappings once, without interfering
with system headers, upstream macros, or unity builds. It makes builds
more robust.
Also:
- checksrc: ban all mapped functions.
- docs/examples: tidy up checksrc rules.

- codespell: break logic out into its own runnable script. Allowing
to run it on local machines.
- codespell: install via `pip`, bump to latest version.
- codespell: show version number in CI log.
- codespell: drop no longer needed word exception: `msdos`.
- codespell: include all curl source tree, except `packages` and
`winbuild`. Drop an obsolete file exclusion.
- add new spellchecker job using the `typos` tool. It includes
the codespell dictionary and a couple more. Use linuxbrew to install
it. This takes 10 seconds, while installing via `cargo` from source
would take over a minute.
- codespell: introduce an inline ignore filter compatible with `cspell`
Make `typos` recognize it, too. Move single exceptions inline.
Fix new typos found. Also rename variables and words to keep
spellchecking exceptions at minumum. This involves touching some tests.
Also switch base64 strings to `%b64[]` to avoid false positives.

Closes#16744
Before this patch, standard `E*` errno codes were redefined on Windows,
onto matching winsock2 `WSA*` error codes, which have different values.
This broke uses where using the `E*` value in non-socket context, or
other places expecting a POSIX `errno`, e.g. file I/O, threads, IDN or
interfacing with dependencies.
Fix it by introducing a curl-specific `SOCKE*` set of macros that map to
`WSA*` on Windows and standard POSIX codes on other platforms. Then
verify and update the code to use `SOCKE*` or `E*` macro depending on
context.
- Add `SOCKE*` macros that map to either winsock2 or POSIX error codes.
And use them with `SOCKERRNO` or in contexts requiring
platform-dependent socket error codes.
This fixes `E*` uses which were supposed be POSIX values, not `WSA*`
socket errors, on Windows:
- lib/curl_multibyte.c
- lib/curl_threads.c
- lib/idn.c
- lib/vtls/gtls.c
- lib/vtls/rustls.c
- src/tool_cb_wrt.c
- src/tool_dirhie.c
- Ban `E*` codes having a `SOCKE*` mapping, via checksrc.

- Add exceptions for `E*` codes used in file I/O, or other contexts
requiring POSIX error codes.
Also:
- ftp: fix missing `SOCKEACCES` mapping for Windows.
- add `SOCKENOMEM` for `Curl_getaddrinfo()` via `asyn-thread.c`.
- tests/server/sockfilt: fix to set `SOCKERRNO` in local `select()`
override on Windows.
- lib/inet_ntop: fix to return `WSAEINVAL` on Windows, where `ENOSPC` is
used on other platforms. To simulate Windows' built-in `inet_ntop()`,
as tested on a Win10 machine.
Note:
- WINE returns `STATUS_INVALID_PARAMETER` = `0xC000000D`.
- Microsoft documentation says it returns `WSA_INVALID_PARAMETER`
(= `ERROR_INVALID_PARAMETER`) 87:
https://learn.microsoft.com/windows/win32/api/ws2tcpip/nf-ws2tcpip-inet_ntop#return-value
- lib/inet_ntop: drop redundant `CURL_SETERRNO(ENOSPC)`.
`inet_ntop4()` already sets it before returning `NULL`.
- replace stray `WSAEWOULDBLOCK` with `USE_WINSOCK` macro to detect
winsock2.
- move existing `SOCKE*` mappings from `tests/server` to
`curl_setup_once.h`.
- add missing `EINTR`, `EINVAL` constants for WinCE.

Before this patch, `libhostname.so` and `chkhostname` were a test
facility for overriding `gethostname()` in non-debug builds on
Linux and other Unix platforms supporting `LD_PRELOAD`.
`gethostname()` has a single use with SMTP.
The alternative way to override `gethostname()` is building in debug
mode, which allows to do this via the `CURL_GETHOSTNAME` env, on all
platforms.
Drop the `LD_PRELOAD` solution in favour of the above.
Also:
- delete inactive NTLM code with a `gethostname()` call made from it.
- streamline NTLM code by dropping a `printf()` and a macro.
- tests: stop setting `CURL_GETHOSTNAME` where unnecessary.
Closes#14695
- scripts/log2changes.pl was not included in release tarballs, which broke
reproducible builds
- since log2changes uses git to generate the contents, it makes it difficult
to generate the same contents later (it would need to be fixed)
- the CHANGES file has outlived its purpose. the main changes are in the
RELEASE-NOTES, the rest are better tracked directly using git or on GitHub
- put a fixed CHANGES.md in there instead pointing out where the info lives
now

Use PASE perl to run manual generation scripts.
As PASE perl is not aware of all possible input file encoding, convert
all files to UTF-8 upon build start (this might be lengthy).
OS/400 terminal emulation may only offer 76 columns, thus a new -c
parameter has been added to the managen program, defining the allowed
width.
If perl is not available, omit generation and disable online manual.

- prefer `.bat` extension over `.cmd` for MS-DOS batch, which also

- delete a contraction.
- drop backticks from error message.
- use `nmake.exe` consistently.
- use equal/not-equal operator style consistently.
- inline a single-line `if` branch.
- delete exceptions and rules dealing with Windows `.cmd` extension.

We remove support for building curl with gskit.
- This is a niche TLS library, only running on some IBM systems
- no regular curl contributors use this backend
- no CI builds use or verify this backend
- gskit, or the curl adaption for it, lacks many modern TLS features
making it an inferior solution
- build breakages in this code take weeks or more to get detected
- fixing gskit code is mostly done "flying blind"
This removal has been advertized in DEPRECATED in Jan 2, 2023 and it has
been mentioned on the curl-library mailing list.
It could be brought back, this is not a ban. Given proper effort and
will, gskit support is welcome back into the curl TLS backend family.
