New methods to access mailbox.Maildir message info and flags:
get_info, set_info, get_flags, set_flags, add_flag, remove_flag.
These methods speed up accessing a message's info and/or flags and are
useful when it is not necessary to access the message's contents,
as when iterating over a Maildir to find messages with specific flags.

Now all results from worker processes are aggregated and
displayed together as a summary at the end of a regrtest run.
The traditional trace is left in place for use with sequential
in-process test runs but now raises a warning that those
numbers are not precise.
`-T -j` requires `--with-pydebug` as it relies on `-Xpresite=`.
Drop posix.fallocate() under WASI.
The underlying POSIX function, posix_fallocate(), was found to vary too
much between implementations to remain in WASI. As such, while it was
available in WASI preview1, it's been dropped in preview2.
Critical sections are helpers to replace the global interpreter lock
with finer grained locking. They provide similar guarantees to the GIL
and avoid the deadlock risk that plain locking involves. Critical
sections are implicitly ended whenever the GIL would be released. They
are resumed when the GIL would be acquired. Nested critical sections
behave as if the sections were interleaved.

Joining a thread now ensures the underlying OS thread has exited. This is required for safer fork() in multi-threaded processes.

Use Argument Clinic for time.clock_gettime() and
time.clock_gettime_ns() functions.
Benchmark on time.clock_gettime_ns():
import time
import pyperf
runner = pyperf.Runner()
runner.timeit(
'clock_gettime_ns(CLOCK_MONOTONIC_COARSE)',
setup='import time; clock_gettime_ns=time.clock_gettime_ns; CLOCK_MONOTONIC_COARSE=6',
stmt='clock_gettime_ns(CLOCK_MONOTONIC_COARSE)')
Result on Linux with CPU isolation:
Mean +- std dev: [ref] 134 ns +- 1 ns -> [change] 55.7 ns +- 1.4 ns: 2.41x faster
- There is no longer a separate Python/executor.c file.
- Conventions in Python/bytecodes.c are slightly different -- don't use `goto error`,
you must use `GOTO_ERROR(error)` (same for others like `unused_local_error`).
- The `TIER_ONE` and `TIER_TWO` symbols are only valid in the generated (.c.h) files.
- In Lib/test/support/__init__.py, `Py_C_RECURSION_LIMIT` is imported from `_testcapi`.
- On Windows, in debug mode, stack allocation grows from 8MiB to 12MiB.
- **Beware!** This changes the env vars to enable uops and their debugging
to `PYTHON_UOPS` and `PYTHON_LLTRACE`.
