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.

88c29877c7 Close #19741: tracemalloc_realloc() does not release the table lock anymore 
between tracemalloc_remove_trace() and tracemalloc_add_trace() to reduce the
risk of race condition.

tracemalloc_add_trace() cannot fail anymore in tracemalloc_realloc() when
tracemalloc_realloc() resizes a memory block.

tracemalloc_add_trace/remove_trace().

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.

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.
