build: add Windows CE / CeGCC support, with CI jobs
Make it possible to build curl for Windows CE using the CeGCC toolchain.
With both CMake and autotools, including tests and examples, also in CI.
The build configuration is the default one with Schannel enabled. No
3rd-party dependencies have been tested.

Also revive old code to make Schannel build with Windows CE, including
certificate verification.

Builds have been throughougly tested. But, I've made no functional tests
for this PR. Some parts (esp. file operations, like truncate and seek)
are stubbed out and likely broken as a result. Test servers build, but
they do not work on Windows CE. This patch substitutes `fstat()` calls
with `stat()`, which operate on filenames, not file handles. This may or
may not work and/or may not be secure.

About CeGCC: I used the latest available macOS binary build v0.59.1
r1397 from 2009, in native `mingw32ce` build mode. CeGCC is in effect
MinGW + GCC 4.4.0 + old/classic-mingw Windows headers. It targets
Windows CE v3.0 according to its `_WIN32_WCE` value. It means this PR
restores portions of old/classic-mingw support. It makes the Windows CE
codepath compatible with GCC 4.4.0. It also adds workaround for CMake,
which cannot identify and configure this toolchain out of the box.

Notes:
- CMake doesn't recognize CeGCC/mingw32ce, necessitating tricks as seen
  with Amiga and MS-DOS.
- CMake doesn't set `MINGW` for mingw32ce. Set it and `MINGW32CE`
  manually as a helper variable, in addition to `WINCE` which CMake sets
  based on `CMAKE_SYSTEM_NAME`.
- CMake fails to create an implib for `libcurl.dll`, due to not
  recognizing the platform as a Windowsy one. This patch adds the
  necessary workaround to make it work.
- headers shipping with CeGCC miss some things curl needs for Schannel
  support. Fixed by restoring and renovating code previously deleted
  old-mingw code.
- it's sometime non-trivial to figure out if a fallout is WinCE,
  mingw32ce, old-mingw, or GCC version-specific.
- WinCE is always Unicode. With exceptions: no `wmain`,
  `GetProcAddress()`.
- `_fileno()` is said to convert from `FILE *` to `void *` which is
  a Win32 file `HANDLE`. (This patch doesn't use this, but with further
  effort it probably could be.)
  https://stackoverflow.com/questions/3989545/how-do-i-get-the-file-handle-from-the-fopen-file-structure
- WinCE has no signals, current directory, stdio/CRT file handles, no
  `_get_osfhandle()`, no `errno`, no `errno.h`. Some of this stuff is
  standard C89, yet missing from this platform. Microsoft expects
  Windows CE apps to use Win32 file API and `FILE *` exclusively.
- revived CeGCC here (not tested for this PR):
  https://building.enlyze.com/posts/a-new-windows-ce-x86-compiler-in-2024/

On `UNDER_CE` vs. `_WIN32_WCE`: (This patch settled on `UNDER_CE`)

- A custom VS2008 WinCE toolchain does not set any of these.
  The compiler binaries don't contain these strings, and has no compiler
  option for targeting WinCE, hinting that a vanilla toolchain isn't
  setting any of them either.
- `UNDER_CE` is automatically defined by the CeGCC compiler.
  https://cegcc.sourceforge.net/docs/details.html
- `UNDER_CE` is similar to `_WIN32`, except it's not set automatically
  by all compilers. It's not supposed to have any value, like a version.
  (Though e.g. OpenSSL sets it to a version)
- `_WIN32_WCE` is the CE counterpart of the non-CE `_WIN32_WINNT` macro.
  That does return the targeted Windows CE version.
- `_WIN32_WCE` is not defined by compilers, and relies on a header
  setting it to a default, or the build to set it to the desired target
  version. This is also how `_WIN32_WINNT` works.
- `_WIN32_WCE` default is set by `windef.h` in CeGCC.
- `_WIN32_WCE` isn't set to a default by MSVC Windows CE headers (the
  ones I checked at least).
- CMake sets `_WIN32_WCE=<ver>`, `UNDER_CE`, `WINCE` for MSVC WinCE.
- `_WIN32_WCE` seems more popular in other projects, including CeGCC
  itself. `zlib` is a notable exception amongst curl dependencies,
  which uses `UNDER_CE`.
- Since `_WIN32_WCE` needs "certain" headers to have it defined, it's
  undefined depending on headers included beforehand.
- `curl/curl.h` re-uses `_WIN32_WCE`'s as a self-guard, relying on
  its not-(necessarily)-defined-by-default property:
  25b445e479/include/curl/curl.h (L77)

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.

system.h: drop compilers lacking 64-bit integer type (Windows/MS-DOS)
- DJGPP 1.x (including `__GO32__`) (MS-DOS)
  DJGPP 2.x support remains unchanged.
- Salford C (Windows)
- Turbo C (Windows 16-bit)
- Borland C++ < 5.2 (Windows 16-bit?)
- Pelles C < 2.8 (Windows)

These targets mapped `curl_off_t` to `long`. On Windows and MS-DOS
`long` is always 32-bit.

curl requires C compilers supporting 64-bit `curl_off_t` type since
835682661c #10597 (v8.0.0).

Also: drop remaining `__GO32__` and Salford C guards.

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.

build: fix MSVC UWP builds
The MSVC UWP job in CI did not actually enable UWP. Fix this and
the fallouts discovered after enabling it.

- GHA/windows: make sure to enable UWP in MSVC vcpkg UWP job.
  Use the CMake options and C flags already used for mingw-w64, but use
  `WINAPI_FAMILY_PC_APP` instead of the deprecated `WINAPI_FAMILY_APP`.
  (The former is not supported by mingw-w64, so leave it there as-is.)
  Follow-up to cb22cfca69 #14077

- GHA/windows: by default the MSVC UWP job became 2x-3x slower than
  others after actually enabling UWP. Most of it is caused by
  CMake/MSBuild automatically building full APPX containers for each
  `.exe` target. This includes 21 CMake feature detections. Each
  detection app is built into a 15MB APPX project, with code signing,
  logos, etc. Example:
    https://github.com/curl/curl/actions/runs/12056968170/job/33620610958
  Disable this overhead for curl build targets via custom
  `CMAKE_VS_GLOBALS` options. I've found no way to apply them to feature
  detection targets, so those remain slow.

- cmake: automatically enable Unicode for UWP builds. It's required.
  Also stop enabling it manually in the existing CI job.

- tests: fix `getpid()` use for Windows UWP:
  ```
  tests\server\util.c(281,21): warning C4013: 'getpid' undefined; assuming extern returning int
  ```
  Ref: https://github.com/curl/curl/actions/runs/12061215311/job/33632904249#step:11:38

- src/tool_doswin: disable `GetLoadedModulePaths()` for UWP.
  mingw-w64 UWP was okay with this, but MS SDK headers are not.
  This makes `--dump-module-paths` return empty for UWP builds.
  ```
  src\tool_doswin.c(620,3): error C2065: 'MODULEENTRY32': undeclared identifier
  src\tool_doswin.c(626,11): warning C4013: 'CreateToolhelp32Snapshot' undefined; assuming extern returning int

  ```

  ```
  LINK : warning LNK4075: ignoring '/INCREMENTAL' due to '/OPT:ICF' specification
  ```
  Ref: https://github.com/curl/curl/actions/runs/12055696808/job/33616629610#step:11:38

  performance a little.

curl: add options for safe/no CA bundle search (Windows)
Add `CURL_CA_SEARCH_SAFE` build-time option to enable CA bundle search
in the `curl` tool directory. The lookup method was already used to find
`.curlrc` and `_curlrc` (on Windows). On Windows it overrides the unsafe
default `SearchPath()` method.

Enable with:
- cmake: `-DCURL_CA_SEARCH_SAFE=ON`
- autotools: `--enable-ca-search-safe`
- raw: `CPPFLAGS=-DCURL_CA_SEARCH_SAFE`

On Windows, before this patch the whole `PATH` was searched for
a CA bundle. `PATH` may contain unwanted or world-writable locations,
including the current directory. Searching them all is convenient to
pick up any CA bundle, but not secure.

The Muldersoft curl distro implements such CA search via a custom
patch for Windows:
cd652d4792/patch/curl_tool_doswin.diff (L50)

MSYS2/mingw-w64 distro has also been rolling a patch solving this:
https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-curl/0001-Make-cURL-relocatable.patch
https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-curl/pathtools.c

Also add option to fully disable Windows CA search:
- cmake: `-DCURL_DISABLE_CA_SEARCH=ON`
- autotools: `--disable-ca-search`
- raw: `CPPFLAGS=-DCURL_DISABLE_CA_SEARCH`.

Both options are considered EXPERIMENTAL, with possible incompatible
changes or even (partial) removal in the future, depending on feedback.

An alternative, secure option is to embed the CA bundle into the binary.

Safe search can be extended to other platforms if necessary or useful,
by using `_NSGetExecutablePath()` (macOS),
`/proc/self/exe` (Linux/Cygwin), or `argv[0]`.

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.

5044909ca2 version_win32: use actual version instead of manifested version
- Use RtlVerifyVersionInfo instead of VerifyVersionInfo, when possible.

Later versions of Windows have normal version functions that compare and
return versions based on the way the application is manifested, instead
of the actual version of Windows the application is running on. We
prefer the actual version of Windows so we'll now call the Rtl variant
of version functions (RtlVerifyVersionInfo) which does a proper
comparison of the actual version.

3831043eff tool_doswin: Restore original console settings on CTRL signal
- Move Windows terminal init code from tool_main to tool_doswin.

- Restore the original console settings on CTRL+C and CTRL+BREAK.

Background: On Windows the curl tool changes the console settings to
enable virtual terminal processing (eg color output) if supported
(ie Win 10). The original settings are restored on exit but prior to
this change were not restored in the case of the CTRL signals.

Windows VT behavior varies depending on console/powershell/terminal;
refer to the discussion in #6226.

1fc0617dcc tool_util: Improve Windows version of tvnow()
- Change tool_util.c tvnow() for Windows to match more closely to
  timeval.c Curl_now().

- Create a win32 init function for the tool, since some initialization
  is required for the tvnow() changes.

Prior to this change the monotonic time function used by curl in Windows
was determined at build-time and not runtime. That was a problem because
when curl was built targeted for compatibility with old versions of
Windows (eg _WIN32_WINNT < 0x0600) it would use GetTickCount which wraps
every 49.7 days that Windows has been running.

This change makes curl behave similar to libcurl's tvnow function, which
determines at runtime whether the OS is Vista+ and if so calls
QueryPerformanceCounter instead. (Note QueryPerformanceCounter is used
because it has higher resolution than the more obvious candidate
GetTickCount64). The changes to tvnow are basically a copy and paste but
the types in some cases are different.

9c1806ae46 build: Disable Visual Studio warning "conditional expression is constant"
- Disable warning C4127 "conditional expression is constant" globally
  in curl_setup.h for when building with Microsoft's compiler.

This mainly affects building with the Visual Studio project files found
in the projects dir.

Prior to this change the cmake and winbuild build systems already
disabled 4127 globally for when building with Microsoft's compiler.
Also, 4127 was already disabled for all build systems in the limited
circumstance of the WHILE_FALSE macro which disabled the warning
specifically for while(0). This commit removes the WHILE_FALSE macro and
all other cruft in favor of disabling globally in curl_setup.

Background:

We have various macros that cause 0 or 1 to be evaluated, which would
cause warning C4127 in Visual Studio. For example this causes it:

    #define Curl_resolver_asynch() 1

Full behavior is not clearly defined and inconsistent across versions.
However it is documented that since VS 2015 Update 3 Microsoft has
addressed this somewhat but not entirely, not warning on while(true) for
example.

Prior to this change some C4127 warnings occurred when I built with
Visual Studio using the generated projects in the projects dir.

  'th32ModuleID' of 'MODULEENTRY32 {aka struct tagMODULEENTRY32}'
  [-Wmissing-field-initializers]

This is sort of a bogus warning as the remaining members will be set
to zero by the compiler, as all omitted members are. Nevertheless,
remove the warning by omitting all members and setting the dwSize
members explicitly.

397664a065 tool: add undocumented option --dump-module-paths for win32
- Add an undocumented diagnostic option for Windows to show the full

  initialization succeeds.

This is needed so that in the CI we can get a list of all DLL
dependencies after initialization (when they're most likely to have
finished loading) and then package them as artifacts so that a
functioning build can be downloaded. Also I imagine it may have some use
as a diagnostic for help requests.

8996300211 schannel: add support for CURLOPT_CAINFO
- Move verify_certificate functionality in schannel.c into a new
  file called schannel_verify.c. Additionally, some structure defintions
  from schannel.c have been moved to schannel.h to allow them to be
  used in schannel_verify.c.

- Make verify_certificate functionality for Schannel available on
  all versions of Windows instead of just Windows CE. verify_certificate
  will be invoked on Windows CE or when the user specifies
  CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER.

- In verify_certificate, create a custom certificate chain engine that
  exclusively trusts the certificate store backed by the CURLOPT_CAINFO
  file.

- doc updates of --cacert/CAINFO support for schannel

- Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString
  when available. This implements a TODO in schannel.c to improve
  handling of multiple SANs in a certificate. In particular, all SANs
  will now be searched instead of just the first name.

- Update tool_operate.c to not search for the curl-ca-bundle.crt file
  when using Schannel to maintain backward compatibility. Previously,
  any curl-ca-bundle.crt file found in that search would have been
  ignored by Schannel. But, with CAINFO support, the file found by
  that search would have been used as the certificate store and
  could cause issues for any users that have curl-ca-bundle.crt in
  the search path.

- Update url.c to not set the build time CURL_CA_BUNDLE if the selected
  SSL backend is Schannel. We allow setting CA location for schannel
  only when explicitly specified by the user via CURLOPT_CAINFO /
  --cacert.

- Add new test cases 3000 and 3001. These test cases check that the first
  and last SAN, respectively, matches the connection hostname. New test
  certificates have been added for these cases. For 3000, the certificate
  prefix is Server-localhost-firstSAN and for 3001, the certificate
  prefix is Server-localhost-secondSAN.

- Remove TODO 15.2 (Add support for custom server certificate
  validation), this commit addresses it.

- Add unit test 1604 to test the sanitize_file_name function.

- Better detection of reserved DOS device names.

- New flags to modify sanitize behavior:

SANITIZE_ALLOW_COLONS: Allow colons
SANITIZE_ALLOW_PATH: Allow path separators and colons
SANITIZE_ALLOW_RESERVED: Allow reserved device names
SANITIZE_ALLOW_TRUNCATE: Allow truncating a long filename

- Restore sanitization of banned characters from user-specified outfile.

Prior to this commit sanitization of a user-specified outfile was
temporarily disabled in 2b6dadc because there was no way to allow path
separators and colons through while replacing other banned characters.
Now in such a case we call the sanitize function with
SANITIZE_ALLOW_PATH which allows path separators and colons to pass
through.
