6bf41e54a4 Remove explicit empty tuple reuse in cpickle. 
PyTuple_New(0) always returns the same empty tuple from its free list anyway,
so we are not saving much here. Plus, the code where this was used is on
uncommon run paths.

b13e6bcbd8 Remove the tuple reuse optimization in _Pickle_FastCall. 
I have noticed a race-condition occurring on one of the buildbots because of
this optimization. The function called may release the GIL which means
multiple threads may end up accessing the shared tuple. I could fix it up by
storing the tuple to the Pickler and Unipickler object again, but honestly it
really not worth the trouble.

I ran many benchmarks and the only time the optimization helps is when using a
fin-memory file, like io.BytesIO on which reads are super cheap, combined with
pickle protocol less than 4. Even in this contrived case, the speedup is a
about 5%. For everything else, this optimization does not provide any
noticable improvements.

23bdd83053 Encapsulate cpickle global state in a dedicated object. 
This implements PEP 3121 module finalization as well. This change does not
cause any significant impact on performance.

f28ce60441 Closes #19786: tracemalloc, remove the arbitrary limit of 100 frames 
The limit is now 178,956,969 on 64 bit (it is greater on 32 bit because
structures are smaller).

Use int instead of Py_ssize_t to store the number of frames to have smaller
traceback_t objects.

000de53624 Issue #19752: Fix "HAVE_DEV_PTMX" implementation of os.openpty() 
Regression introduced by the implementation of the PEP 446 (non-inheritable
file descriptors by default).

master_fd must be set non-inheritable after the creation of the slave_fd,
otherwise grantpt(master_fd) fails with EPERM (errno 13).

ed8c906127 Use Clinic to process arguments in cpickle. 
This doesn't make any functional changes to the exisiting implementation.  The
conversion did help however uncover documentation bugs. The best thing about
this conversion is less C code to maintain by hand.

45059eb1d0 1) Prepare libmpdec for the 2.4.0 release. None of the following changes affects 
_decimal:

      o Make all "mpd_t to C integer" conversion functions available in both the
        64-bit and the 32-bit versions.

      o Make all mixed mpd_t/C integer arithmetic functions available in the
        32-bit version.

      o Better handling of __STDC_LIMIT_MACROS for C++ users.

      o Add struct tags (at the request of C++ users).

2) Check for libmpdec.so.2 if --with-system-libmpdec is used.

b6a2f2a0d1 Make framing optional in pickle protocol 4. 
This will allow us to control in the future whether to use framing or not.
For example, we may want to turn it off for tiny pickle where it doesn't
help.

The change also improves performance slightly:
