While file timestamps can be anything the file system can store, most
lie between the recent past and the near future. Optimize fill_time()
for typical timestamps in three ways:
- When possible, convert to nanoseconds with C arithmetic.
- When using C arithmetic and the seconds member is not required (for
st_birthtime), avoid creating a long object.
- When using C arithmetic, reorder the code to avoid the null checks
implied in Py_XDECREF().

The signature algorithms allowed for certificate-based client authentication or
for the server to complete the TLS handshake can be defined on a SSL context via
`ctx.set_client_sigalgs()` and `ctx.set_server_sigalgs()`.
With OpenSSL 3.4 or later, the list of available TLS algorithms can be retrieved
by `ssl.get_sigalgs()`.
With OpenSSL 3.5 or later, the selected signature algorithms can be retrieved from
SSL sockets via `socket.client_sigalg()` and `socket.server_sigalg()`.
This commit also partially amends 377b787618
by using `PyUnicode_DecodeFSDefault` instead of `PyUnicode_DecodeASCII` in
`_ssl._SSLContext.get_groups`, so that functions consistently decode strings
obtained from OpenSSL.

It should interpret the result of wcsxfrm() as a sequence of abstract
integers, not a sequence of Unicode code points or using other encoding
scheme that does not preserve ordering.
Previously, the size would be returned on Windows and an OSError would
be raised on Unix.
Also, raise ValueError instead of OSError for trackfd=False.

Encode Solaris/Illumos thread names to ASCII, since
OpenIndiana does not support non-ASCII names.
Add tests for setting non-ASCII name for the main thread.

Don't ignore errors raised by `PyErr_WarnFormat` in `warn_about_fork_with_threads`
Instead, ignore the warnings in all test code that forks. (That's a lot of functions.)
In `test_support`, make `ignore_warnings` a context manager (as well as decorator),
and add a `message` argument to it.
Also add a `ignore_fork_in_thread_deprecation_warnings` helper for the deadlock-in-fork
warning.
The csv.register_dialect() docstring no longer imply that it returns a
dialect.
All functions have now signatures.

A runtime check is needed to support cross-compiling.
Remove the _Py_NORMALIZE_CENTURY macro.
Remove _pydatetime.py's _can_support_c99.

It is now a positive integer larger larger than any limited resource value.
This simplifies comparison of the resource values.
Previously, it could be negative, such as -1 or -3, depending on platform.
Deprecation warning is emitted if the old negative value is passed.
The Python pickle module looks for "00" and "01" but _pickle only looked
for 2 characters that parsed to 0 or 1, meaning some payloads like "+0" or
" 0" would lead to different results in different implementations.
