Add a configure define for HAVE_PTHREAD_COND_TIMEDWAIT_RELATIVE_NP and
replaces pthread_cond_timedwait() with pthread_cond_timedwait_relative_np()
for relative time when supported in semaphore waiting logic.
Return files and directories from `pathlib.Path.glob()` if the pattern ends
with `**`. This is more compatible with `PurePath.full_match()` and with
other glob implementations such as bash and `glob.glob()`. Users can add a
trailing slash to match only directories.
In my previous patch I added a `FutureWarning` with the intention of fixing
this in Python 3.15. Upon further reflection I think this was an
unnecessarily cautious remedy to a clear bug.
Raise `ValueError` if `with_suffix('.ext')` is called on a path without a
stem. Paths may only have a non-empty suffix if they also have a non-empty
stem.
ABC-only bugfix; no effect on public classes.

nedbat took issue with the phrasing "real module". I'm actually fine
with that phrasing, but I do think the `__future__` page should be clear
about the way in which the `__future__` module is special. (Yes, there
was a footnote linking to the future statements part of the reference,
but there should be upfront discussion).
I'm sympathetic to nedbat's claim that no one really cares about
`__future__._Feature`, so I've moved the interesting table up to the
top.
My criterion for delayed imports is that they're only worth it if the
majority of users of the module would benefit from it, otherwise you're
just moving latency around unpredictably.
mktime_tz is not used anywhere in the standard library and grep.app
indicates it's not got much use in the ecosystem either.
Distribution.files is not nearly as widely used as other
importlib.metadata APIs, so we defer the csv import.
Before:
```
λ hyperfine -w 8 './python -c "import importlib.metadata"'
Benchmark 1: ./python -c "import importlib.metadata"
Time (mean ± σ): 65.1 ms ± 0.5 ms [User: 55.3 ms, System: 9.8 ms]
Range (min … max): 64.4 ms … 66.4 ms 44 runs
```
After:
```
λ hyperfine -w 8 './python -c "import importlib.metadata"'
Benchmark 1: ./python -c "import importlib.metadata"
Time (mean ± σ): 62.0 ms ± 0.3 ms [User: 52.5 ms, System: 9.6 ms]
Range (min … max): 61.3 ms … 62.8 ms 46 runs
```
for about a 3ms saving with warm disk cache, maybe 7-11ms with cold disk
cache.
Add an option (--enable-experimental-jit for configure-based builds
or --experimental-jit for PCbuild-based ones) to build an
*experimental* just-in-time compiler, based on copy-and-patch
(https://fredrikbk.com/publications/copy-and-patch.pdf).
See Tools/jit/README.md for more information, including how to install the required build-time tooling. Merry JIT-mas! ;)

Remove `self.joinpath('')` call that should have been removed in 6313cdde.
This makes `PathBase.glob('')` yield itself *without* adding a trailing slash. It's hard to say whether this is more or less correct, but at least everything else is faster, and there's no behaviour change in the public classes where empty glob patterns are disallowed.
