* introduce executable specific linker flags
Add PY_CORE_EXE_LDFLAGS and EXE_LDFLAGS which stores executable specific
LDFLAGS, replacing PY_CORE_LDFLAGS for building
executable targets.
If PY_CORE_EXE_LDFLAGS / EXE_LDFLAGS is not provided, then it defaults
to the value of PY_CORE_LDFLAGS which is the existing behaviour.
If both flags are supplied, and there is a need
to distinguish between executable and shared specific LDFLAGS,
in particular, PY_CORE_LDFLAGS should contain the shared specific LDFLAGS.
* documentation for new linker flags
* update Misc folder documentation
* Update Makefile.pre.in

The handle parameter was being ignored in the POSIX implementation
of CDLL._load_library(), causing it to always call _dlopen() even
when a valid handle was provided. This was a regression introduced
in recent refactoring.
Since os.stat() raises an OSError for existing named pipe "\\.\pipe\...",
os.path.exists() always returns False for it, and tempfile.mktemp() can
return a name that matches an existing named pipe.
So, tempfile.mktemp() cannot be used to generate unique names for named
pipes. Instead, CreateNamedPipe() should be called in a loop with
different names until it completes successfully.
Add SIMD optimization for `bytes.hex()`, `bytearray.hex()`, and `binascii.hexlify()` as well as `hashlib` `.hexdigest()` methods using platform-agnostic GCC/Clang vector extensions that compile to native SIMD instructions on our [PEP-11 Tier 1 Linux and macOS](https://peps.python.org/pep-0011/#tier-1) platforms.
- 1.1-3x faster for common small data (16-64 bytes, covering md5 through sha512 digest sizes)
- Up to 11x faster for large data (1KB+)
- Retains the existing scalar code for short inputs (<16 bytes) or platforms lacking SIMD instructions, no observable performance regressions there.
## Supported platforms:
- x86-64: the compiler generates SSE2 - always available, no flags or CPU feature checks needed
- ARM64: NEON is always available, always available, no flags or CPU feature checks needed
- ARM32: Requires NEON support and that appropriate compiler flags enable that (e.g., `-march=native` on a Raspberry Pi 3+) - while we _could_ use runtime detection to allow neon when compiled without a recent enough `-march=` flag (`cortex-a53` and later IIRC), there are diminishing returns in doing so. Anyone using 32-bit ARM in a situation where performance matters will already be compiling with such flags. (as opposed to 32-bit Raspbian compilation that defaults to aiming primarily for compatibility with rpi1&0 armv6 arch=armhf which lacks neon)
- Windows/MSVC: Not supported. MSVC lacks `__builtin_shufflevector`, so the existing scalar path is used. Leaving it as an opportunity for the future for someone to figure out how to express the intent to that compiler.
This is compile time detection of features that are always available on the target architectures. No need for runtime feature inspection.
PyDict_Contains() and PyDict_ContainsString() now fail with
SystemError if the first argument is not a dict, frozendict, dict
subclass or frozendict subclass.
PyDict_MergeFromSeq2() now fails with SystemError if the first
argument is not a dict or a dict subclass.
PyDict_Update(), PyDict_Merge() and _PyDict_MergeEx() no longer
accept frozendict.
Fix an issue where passing invalid arguments to `os.posix_spawn[p]` functions
raised a SystemError instead of a TypeError, and allow to explicitly use `None`
for `scheduler` and `setpgroup` as specified in the docs.
specifically configure --without-builtin-hashlib-hashes means the otherwise guaranteed available blake2 family will not exist. this allows the test suite to still pass.
The fix for gh-92081 (gh-92281) was unfortunately flawed, and broke whitespace handling for encoded word patterns that had previously been working correctly but had no corresponding tests, unfortunately in a way that made the resulting headers not RFC compliant, in such a way that Yahoo started rejecting the resulting emails. This fix was released in 3.14 alpha 1, 3.13 beta 2 and 3.12.5. This PR fixes the original problem in a way that does not break anything, and in fact fixes a small pre-existing bug (a spurious whitespace after the ':' of the header label if the header value is immediately wrapped on to the next line).
