MSVC doesn't define any endianness macros, but for x64 (and ARM64EC) as well as x86 processors MSVC uses little-endian order. We define that accordingly.
MSVC does not support any inline assembly (let alone symversioning).
`ssize_t` is not supported, but `SSIZE_T` with the same meaning.
MSVC doesn't support `explicit_memset()` nor `memset_s()`, but has `SecureZeroMemory()`, which appears to be more appropriate than falling back on an own function definition.

This does a full client build of libxcrypt, using upstream's autotools based build chain on MSYS2, but using MSVC build tools. This requires wrappers for the MSVC build tools; ar-lib and compile are taken unmodified from automake; windres is a minimalist self-made wrapper. A prerequisite is a suitable libxcrypt patched to support MSVC builds[1]. [1] <besser82/libxcrypt#195>

This PR solves a couple of mostly minor issues (see individual commit messages for details) which prevent building the static crypt.lib with MSVC on Windows. For building a shared library (DLL) exported functions would need to be decorated with
__declspec(dllexport)and__declspec(dllimport), respectively (see 'win32-dll' argument ofLT_INIT()).The biggest hurdle is that autoconf currently (2.72) does not properly recognize C11 support (only has recently been fixed in the development branch). I worked around that with the following hack:
Closes #193.
