5c66189e88 Issue #20189: Four additional builtin types (PyTypeObject, 
PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
have been modified to provide introspection information for builtins.
Also: many additional Lib, test suite, and Argument Clinic fixes.

462582651c Two minor Argument Clinic bugfixes: use the name of the class in the 
docstring for __new__ and __init__, and always use "goto exit" instead of
returning "NULL" for failure to parse (as _new__ and __init__ return ints).

d05c9ff845 Issue #6784: Strings from Python 2 can now be unpickled as bytes objects. 
Initial patch by Merlijn van Deen.

I've added a few unrelated docstring fixes in the patch while I was at
it, which makes the documentation for pickle a bit more consistent.

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.

20c28c1ea2 Combine the FastCall functions in cpickle.

the full test suite to verify I didn't introduce any obvious bugs.

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.

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:
