tidy-up: delete, comment or scope C macros reported unused
To reduce the number `-Wunused-macro` compiler warnings:
- delete unused macros.
- comment out unused macro that are part of a set.
- move macros into the scope they are used.

This may be useful to enable by default, but there are tricky cases that
I didn't manage to fix and paused the effort. E.g. internal features
checks in `openssl.c`. There is more, once those are fixed.

netrc: return code cleanup, fix missing file error
Made the netrc parser return a more consistent set of error codes and
error messages, and also return error properly if the .netrc file is
missing.

netrc: fix password-only entries
When a specific hostname matched, and only a password is set before
another machine is specified in the netrc file, the parser would not be
happy and stop there and return the password-only state. It instead
continued and did not return a match.

Add test 2005 to verify this case

Regression from e9b9bba, shipped in 8.11.1.

Makefile.mk: drop in favour of autotools and cmake (MS-DOS, AmigaOS3)
`Makefile.mk` supported MS-DOS and Amiga, but `./configure` also
supported them in a better tested and more flexible way.

This patch also adds CMake support for MS-DOS/DJGPP and Amiga OS 3.

`Makefile.mk` was not maintained. Delete it in favour of first-tier
build methods.

Also include some non-MS-DOS/AmigaOS-specific tidy-up, see details at
the end of this message.

Details:

- fix/silence all MS-DOS/DJGPP build warnings and issues.
- add MS-DOS support to cmake.
  - default to `ENABLE_THREADED_RESOLVER=OFF` for MS-DOS.
  - add support for `WATT_ROOT`.
  - use static libcurl with MS-DOS.
  - fixup default CMake suffixes/prefixes for DJGPP.
  - disable hidden symbols for MS-DOS. Not supported on MS-DOS.
  - opt-in MS-DOS into `USE_UNIX_SOCKETS`.
- improve MS-DOS support in autotools.
  - default to `--disable-threaded-resolver` for MS-DOS.
- make sure to use `close_s()` (from Watt-32) with autotools and cmake.
  `Makefile.mk` used it before this patch.
- GHA: add DJGPP cmake (~30s) and autotools (~60s) build jobs.
  Also build tests and examples with cmake.
- improve AmigaOS support in autotools:
  - configure: detect `CloseSocket()` when it's a macro.
  - configure: fix `IoctlSocket` detection on AmigaOS.
  - curl-amissl.m4: pass AmiSSL libs to tests/servers.
- add AmigaOS3 support to cmake:
  - cmake: fix `HAVE_IOCTLSOCKET_CAMEL` and
    `HAVE_IOCTLSOCKET_CAMEL_FIONBIO` detections.
  - set necessary system libs.
  - add AmiSSL support.
  - inet_ntop, inet_pton: fix using it for AmigaOS. cmake detects them,
    and they did not compile with AmigaOS.
  - cmake: better sync `gethostname` detection with autotools.
    Fixes detection for AmigaOS, where `gethostname` is a macro.
  - cmake: fix `sys/utime.h` detection on AmigaOS.
  - cmake: force-disable `getaddrinfo` for AmigaOS.
  - cmake: tweak threading and static/shared default for AmigaOS.
  - cmake: rely on manual variable `AMIGA` to enable the platform.
- GHA: add AmigaOS cmake and autotools (~45s) jobs.
  Also build tests and examples with cmake.
- INSTALL: update MS-DOS and AmigaOS build instructions.
- amigaos: fix `-Wpointer-sign` and
  `zero or negative size array '_args'` in `Printf()`.
- amigaos: fix `-Wpointer-sign`
- amigaos: fix `-Wredundant-decls` `errno` and `h_errno`.
- amigaos: brute-force silence `lseek()` size warnings.
- amigaos: server/resolve: silence `-Wdiscarded-qualifiers`.
- amigaos: server/resolve: fix `-Wpointer-sign`.
- amigaos: fix `CURL_SA_FAMILY_T` type.
- nonblock: prefer `HAVE_IOCTLSOCKET_CAMEL_FIONBIO` for AmigaOS.
  `ioctl` is also detected, but fails when used. Make the above override
  it for a successful build.

Non-MS-DOS/AmigeOS-specific tidy-ups:

- configure: sync `sa_family_t` detection with cmake.
- configure: sync `ADDRESS_FAMILY` detection signals with cmake.
- doh: use `CURL_SA_FAMILY_T`.
- lib: drop mingw-specific `CURL_SA_FAMILY_T` workaround.
- cmake: extend instead of override check-specific
  configurations/requirements.
  This allows to honor global requirements added earlier.
  Necessary for AmigaOS for example.
- cmake: omit warning on disabled IPv6 for MS-DOS and AmigaOS.
  No IPv6 support on these platforms. Also sync with autotools.
- lib1960: use libcurl `inet_pton()` wrapper.
- cmake: detect LibreSSL (to match autotools).
- cmake: say the specific OpenSSL flavour detected.
- hostip: add missing `HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID` guard.
- lib: simplify classic mac feature guards.

windows: use built-in _WIN32 macro to detect Windows
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.

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)

netrc: support quoted strings
The .netrc parser now accepts strings within double-quotes in order to
deal with for example passwords containing white space - which
previously was not possible.

A password that starts with a double-quote also ends with one, and
double-quotes themselves are escaped with backslashes, like \". It also
supports \n, \r and \t for newline, carriage return and tabs
respectively.

If the password does not start with a double quote, it will end at first
white space and no escaping is performed.

WARNING: this change is not entirely backwards compatible. If anyone
previously used a double-quote as the first letter of their password,
the parser will now get it differently compared to before. This is
highly unfortunate but hard to avoid.

e8423f9ce1 curl_setup: Add macros for FOPEN_READTEXT, FOPEN_WRITETEXT
- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt"
- Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt"

This change is to explicitly specify when we need to read/write text.
Unfortunately 't' is not part of POSIX fopen so we can't specify it
directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT.

Prior to this change we had an issue on Windows if an application that
uses libcurl overrides the default file mode to binary. The default file
mode in Windows is normally text mode (translation mode) and that's what
libcurl expects.

0f4a03cbb6 free: instead of Curl_safefree()
Since we just started make use of free(NULL) in order to simplify code,
this change takes it a step further and:

- converts lots of Curl_safefree() calls to good old free()
- makes Curl_safefree() not check the pointer before free()

The (new) rule of thumb is: if you really want a function call that
frees a pointer and then assigns it to NULL, then use Curl_safefree().
But we will prefer just using free() from now on.
