collect() should not get an exception, but it does, logging the
exception is enough. Override sys.unraisablehook to decide how to
handle unraisable exceptions.
Py_FatalError() should be avoided whenever possible.
The os.putenv() and os.unsetenv() functions are now always available.
On non-Windows platforms, Python now requires setenv() and unsetenv()
functions to build.
Remove putenv_dict from posixmodule.c: it's not longer needed.
Some portions of the pickle documentation hadn't been updated for the pickle protocol changes in Python 3.8 (new protocol 5, default protocol 4). This PR fixes those docs.

If setenv() C function is available, os.putenv() is now implemented
with setenv() instead of putenv(), so Python doesn't have to handle
the environment variable memory.
Deprecate binhex4 and hexbin4 standards. Deprecate the binhex module
and the following binascii functions:
* b2a_hqx(), a2b_hqx()
* rlecode_hqx(), rledecode_hqx()
* crc_hqx()
Although the underlying libffi issue remains open, adding these
checks have caused problems in third-party projects which are in
widespread use. See the issue for examples.
The corresponding tests have also been skipped.
The comment about the collection rules for the permanent generation was
incorrectly referenced by a comment in gcmodule.c (the comment has been
moved long ago into a header file). Moving the comment into the relevant
code helps with readability and avoids broken references.
test_openssl_version now accepts version 3.0.0.
getpeercert() no longer returns IPv6 addresses with a trailing new line.

On most platforms, the `environ` symbol is accessible everywhere.
In a dylib on OSX, it's not easily accessible, you need to find it with
_NSGetEnviron.
The code was caching the *value* of environ. But a setenv() can change the value,
leaving garbage at the old value. Fix: don't cache the value of environ, just
read it every time.
The readline module now detects if Python is linked to libedit at runtime
on all platforms. Previously, the check was only done on macOS.
If Python is used as a library by a binary linking to libedit, the linker
resolves the rl_initialize symbol required by the readline module against
libedit instead of libreadline, which leads to a segfault.
Take advantage of the existing supporting code to have readline module being
compatible with both situations.
The previous code was raising a `KeyError` for both the Python and C implementation.
This was caused by the specified index of an invalid input which did not exist
in the memo structure, where the pickle stores what objects it has seen.
The malformed input would have caused either a `BINGET` or `LONG_BINGET` load
from the memo, leading to a `KeyError` as the determined index was bogus.

Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList()
functions: the free lists of bound method objects have been removed.
Remove also _PyMethod_Fini() and _PyCFunction_Fini() functions.
* Add GCState type for readability
* gcmodule.c now gets its gcstate from tstate
* _PyGC_DumpShutdownStats() now expects tstate rather than runtime
* Rename "state" to "gcstate" for readability: to avoid confusion
between "state" and "tstate" for example.
* collect() now only expects tstate: it gets gcstate from tstate.
* Pass tstate to _PyErr_xxx() functions
Clear the current thread later in the Python finalization.
* The PyInterpreterState_Delete() function is now responsible
to call PyThreadState_Swap(NULL).
* The tstate_delete_common() function is now responsible to clear the
"autoTSSKey" thread local storage and it only clears it once the
thread state is fully cleared. It allows to still get the current
thread from TSS in tstate_delete_common().
* Factorize code in common between Py_FinalizeEx() and
Py_EndInterpreter().
* Py_EndInterpreter() now also calls _PyWarnings_Fini().
* Call _PyExc_Fini() and _PyGC_Fini() later in the finalization.
