Now that the specializing interpreter works with free threading,
replace ENABLE_SPECIALIZATION_FT with ENABLE_SPECIALIZATION and
replace requires_specialization_ft with requires_specialization.
Also limit the uniquely referenced check to FOR_ITER_RANGE. It's not
necessary for FOR_ITER_GEN and would cause test_for_iter_gen to fail.
Make the deprecated set_type method resets the format, using the
same code as in type initialization.
Implementation note: this was done in PyCPointerType_init
after calling PyCPointerType_SetProto, but was forgotten
after in PyCPointerType_set_type_impl's call to
PyCPointerType_SetProto.
With this change, setting the format is conceptually part of
setting proto (i.e. the pointed-to type).

This ensures the buffers used by the empty `bytearray` and `array.array`
are aligned the same as a pointer returned by the allocator. This is a
more convenient default for interop with other languages that have
stricter requirements of type-safe buffers (e.g. Rust's `&[T]` type)
even when empty.
BufferedReader.read1() could leave the buffered object in a
reentrant (locked) state when an exception was raised while
allocating the output buffer.
This change ensures the internal buffered lock is always released
on error, keeping the object in a consistent state after failures.

Add documentation for the F (complex from two floats) and D (complex
from two doubles) format characters in the struct module docstring.
These format characters were implemented but not documented.

Previously, negative timestamps (representing dates before 1970-01-01) were
not supported on Windows due to platform limitations. The changes introduce a
fallback implementation using the Windows FILETIME API, allowing negative
timestamps to be correctly handled in both UTC and local time conversions.
Additionally, related test code is updated to remove Windows-specific skips
and error handling, ensuring consistent behavior across platforms.

Add the unicodedata.iter_graphemes() function to iterate over grapheme
clusters according to rules defined in Unicode Standard Annex #29.
Add unicodedata.grapheme_cluster_break(), unicodedata.indic_conjunct_break()
and unicodedata.extended_pictographic() functions to get the properties
of the character which are related to the above algorithm.

The internal encoder object returned by undocumented function
json.encoder.c_make_encoder() (aka _json.make_encoder()) crashed
when it was called with non-zero second argument.
The 'exc' field was used by our debug SSL callbacks. Keep the exception
in the normal per-thread state to avoid shared mutable state between
threads.
This also avoids a reference count leak if the Python callback raised an
exception because it can be called multiple times per SSL operation.
