[3.6] bpo-31949: Fixed several issues in printing tracebacks (PyTraceBack_Print()). (GH-4289) (#4406)
* Setting sys.tracebacklimit to 0 or less now suppresses printing tracebacks.
* Setting sys.tracebacklimit to None now causes using the default limit.
* Setting sys.tracebacklimit to an integer larger than LONG_MAX now means using
the limit LONG_MAX rather than the default limit.
* Fixed integer overflows in the case of more than 2**31 traceback items on
Windows.
* Fixed output errors handling..

The authenticate argument does not exist on either Client or Listener:
- https://github.com/python/cpython/blob/master/Lib/multiprocessing/connection.pyGH-L483 (master)
- https://github.com/python/cpython/blob/3.6/Lib/multiprocessing/connection.pyGH-L478 (3.6)

The documentation also claimed that these functions will call `current_process().auth_key`, for which I could find no evidence in the code. I rewrote the documentation to reflect the actual behavior.
bpo-31933: fix blake2 multi-byte params on big endian platforms (GH-4250) (#4262)
All Blake2 params have to be encoded in little-endian byte order. For
the two multi-byte integer params, leaf_length and node_offset, that
means that assigning a native-endian integer to them appears to work on
little-endian platforms, but gives the wrong result on big-endian. The
current libb2 API doesn't make that very clear, and @sneves is working
on new API functions in the GH issue above. In the meantime, we can work
around the problem by explicitly assigning little-endian values to the
parameter block.
When a single .c file contains several functions and/or methods with
the same name, a safety _METHODDEF GH-define statement is generated
only for one of them.
This fixes the bug by using the full name of the function to avoid
duplicates rather than just the name..

Remove nested comments in blake2 (GH-4173) (#4214)
Replace occurence of nested comments in blake2 reference implementation
with preprocessor directive for disabling unused code.
`blake2s-load-xop.h` is conditionally pulled in only on chips with XOP
support, among others the AMD Bulldozer. The malformed comments in the
source file breaks the build of `hashlib`'s `_blake2` on GCC 6.3.0.
bpo-25720: Fix the method for checking pad state of curses WINDOW (GH-4164) (#4212)
Modify the code to use ncurses is_pad() instead of checking WINDOW
_flags field. If your platform does not provide the is_pad(), the
existing way that checks the field will be enabled.
Note: This change does not drop support for platforms where do not
have both WINDOW _flags field and is_pad().

(cherry picked from commit daeefd2e049b74340307481112a39f77de0f4769)
This used to be the case on Python 2. Commit 212b590e118e3650b596917021ed9612a918180b changed the implementation for Python
3, making the `log()` method of LogAdapter call `logger._log()` directly. This
makes nested log adapters not execute their ``process()`` method. This patch
fixes the issue.
Also, now proxying `name`, too, to make `repr()` work with nested log adapters.
