bpo-35368: Make PyMem_Malloc() thread-safe in debug mode (GH-10828) 
When Python is compiled in debug mode, PyMem_Malloc() uses debug
hooks, but it also uses pymalloc allocator instead of malloc().
Problem: pymalloc is not thread-safe, whereas PyMem_Malloc() is
thread-safe in release mode (it's a thin wrapper to malloc() in this
case).

Modify the debug hook to use malloc() for PyMem_Malloc().

Fix compilation warnings on Windows (GH-8627) 
* Fix compilation warning in _ctypes module on Window

(cherry picked from commit 20f11fe43c)

* Fix compilation warnings on Windows 64-bit

(cherry picked from commit 725e421222)

* Fix compiler warning in unicodeobject.c

Explicitly case to Py_UNICODE to fix the warning:

Objects\unicodeobject.c(4225): warning C4244: '=' :
conversion from 'long' to 'Py_UNICODE', possible loss of data

The downcast cannot overflow since we check that value <= 0x10ffff.

[2.7] bpo-32137: The repr of deeply nested dict now raises a RuntimeError (GH-4570) (#5493) 
instead of crashing due to a stack overflow.

This perhaps will fix similar problems in other extension types.

coalesce GILless sections in new_buffersize (#5059) 
830daae1c8 added some new GIL-releasing to new_buffersize. This is fine, but it's better to avoid reacquiring the GIL for as long as possible. Also, it should use FILE_(BEGIN|END)_ALLOW_THREADS to avoid having the file closed from under it.

bpo-31530: fix crash when multiple threads iterate over a file, round 2 (#5060) 
Multiple threads iterating over a file can corrupt the file's internal readahead
buffer resulting in crashes. To fix this, cache buffer state thread-locally for
the duration of a file_iternext call and only update the file's internal state
after reading completes.

No attempt is made to define or provide "reasonable" semantics for iterating
over a file on multiple threads. (Non-crashing) races are still
present. Duplicated, corrupt, and missing data will happen.

This was originally fixed by 6401e56717, which
raised an exception from seek() and next() when concurrent operations were
detected. Alas, this simpler solution breaks legitimate use cases such as
capturing the standard streams when multiple threads are logging.

Nir Soffer 830daae1c8 [2.7] bpo-32186: Release the GIL during fstat and lseek calls (#4651) 
In fileio, there were 3 fstat() calls and one lseek() call that did not
release the GIL during the call. This can cause all threads to hang for
unlimited time when using io.FileIO with inaccessible NFS server.

Same issue seen in fileio exists also in fileobject, fixed in the same
way.

bpo-31626: Fix _PyObject_DebugReallocApi() (#4310) 
_PyObject_DebugReallocApi() now calls Py_FatalError() if realloc()
fails to shrink a memory block.

Call Py_FatalError() because _PyObject_DebugReallocApi() erased freed
bytes *before* realloc(), expecting that realloc() *cannot* fail to
shrink a memory block.
