[3.12] gh-113188: Fix shutil.copymode() and shutil.copystat() on Windows (GH-113285)
Previously they worked differenly if dst is a symbolic link:
they modified the permission bits of dst itself rather than the file
it points to if follow_symlinks is true or src is not a symbolic link,
and did nothing if follow_symlinks is false and src is a symbolic link.

gh-113343: Fix error check on mmap(2) (GH-113342)
Fix error check on mmap(2)
It should check MAP_FAILED instead of NULL for error.
On mmap(2) man page:
RETURN VALUE
On success, mmap() returns a pointer to the mapped area.
On error, the value MAP_FAILED (that is, (void *) -1) is
returned, and errno is set to indicate the error.

gh-112305: Fix check-clean-src to detect frozen_modules .h files. (GH-113344)
A typo left this check broken so many of us who do out-of-tree builds
were seeing strange failures due to bad `Python/frozen_modules/*.h`
files being picked up from the source tree and used at build time from
different Python versions leading to errors like:
`Fatal Python error: _PyImport_InitCore: failed to initialize importlib`
Or similar once our build got to an "invoke the interpreter"
bootstrapping step due to incorrect bytecode being embedded.

When wrapped, `_SSLProtocolTransport._force_close(exc)` is called just like in the unwrapped scenario `_SelectorTransport._force_close(exc)` or `_ProactorBasePipeTransport._force_close(exc)` would be called, except here the exception needs to be passed through the `SSLProtocol._abort()` method, which didn't accept an exception object.
This commit ensures that this path works, in the same way that the uvloop implementation of SSLProto passes on the exception (on which the current implementation of SSLProto is based).

Change _osx_support.get_platform_osx() to make sure that the

minor version (e.g. 14.2) even if MACOSX_DEPLOYMENT_TARGET is
set to just a major version (e.g. 14).
This matches the versions expected by pip when selecting

gh-107959: clarify Unix-availability of `os.lchmod()` (GH-107960)
POSIX specifies that implementations are not required to support changing the
file mode of symbolic links, but may do so.
Consequently, `lchmod()` is not part of POSIX (but mentioned for implementations
which do support the above).
The current wording of the availability of `os.lchmod()` is rather vague and
improved to clearly tell which POSIX/Unix/BSD-like support the function in
general (those that support changing the file mode of symbolic links).
Further, some examples of major implementations are added.
Data for the BSDs taken from their online manpages.

gh-109981: Fix support.fd_count() on macOS 14 (GH-112797)
Use scanning "/dev/fd/" on macOS in support.fd_count(). That's both more efficient than scanning all possible file descriptors, and avoids crashing the interpreter when there are open "guarded" file descriptors.
"Guarded" file descriptors are a macOS feature where file descriptors used by system libraries are marked and cause hard crashes when used by "user" code.

This because on Arm platforms structs with at most 4 elements of any

On x86-64 Linux, it's maximum 16 bytes hence we need to differentiate.
