Py_RunMain() now resets PyImport_Inittab to its initial value at
exit. It must be possible to call PyImport_AppendInittab() or
PyImport_ExtendInittab() at each Python initialization.

No longer use len() to get the length of the input data. For some buffer protocol objects,
the length obtained by using len() is wrong.

Fix asyncio test_popen() of test_windows_utils by using a longer
timeout. Use military grade battle-tested test.support.SHORT_TIMEOUT
timeout rather than a hardcoded timeout of 10 seconds: it's 30
seconds by default, but it is made longer on slow buildbots.
WaitForMultipleObjects() timeout argument is in milliseconds.

_thread.start_new_thread() no longer calls PyThread_exit_thread()
explicitly at the thread exit, the call was redundant.
On Linux with the glibc, pthread_cancel() loads dynamically the
libgcc_s.so.1 library. dlopen() can fail if there is no more
available file descriptor to open the file. In this case, the process
aborts with the error message:
"libgcc_s.so.1 must be installed for pthread_cancel to work"
pthread_cancel() unwinds back to the thread's wrapping function that
calls the thread entry point.
The unwind function is dynamically loaded from the libgcc_s library
since it is tightly coupled to the C compiler (GCC). The unwinder
depends on DWARF, the compiler generates DWARF, so the unwinder
belongs to the compiler.
Thanks Florian Weimer and Carlos O'Donell for their help on
investigating this issue.

* [Enum] reduce scope of new format behavior
Instead of treating all Enums the same for format(), only user mixed-in
enums will be affected. In other words, IntEnum and IntFlag will not be
changing the format() behavior, due to the requirement that they be
drop-in replacements of existing integer constants.
If a user creates their own integer-based enum, then the new behavior
will apply:
class Grades(int, Enum):
A = 5
B = 4
C = 3
D = 2
F = 0
Now: format(Grades.B) -> DeprecationWarning and '4'
3.12: -> no warning, and 'B'.
