[3.6] closes bpo-31532: Fix memory corruption due to allocator mix (GH-3679) (#3681)
Fix a memory corruption in getpath.c due to mixed memory allocators
between Py_GetPath() and Py_SetPath().
The fix use the Raw allocator to mimic the windows version.
This patch should be used from python3.6 to the current version

xml.etree: xmlparser_gc_clear() now sets self.parser to NULL to prevent a
crash in xmlparser_dealloc() if xmlparser_gc_clear() was called previously
by the garbage collector, because the parser was part of a reference cycle.

[3.6] bpo-28556: typing.get_type_hints: better globalns for classes and modules (GH-3582) (#3583)
This makes the default behavior (without specifying `globalns` manually) more
predictable for users, finds the right globalns automatically.
Implementation for classes assumes has a `__module__` attribute and that module
is present in `sys.modules`. It does this recursively for all bases in the
MRO. For modules, the implementation just uses their `__dict__` directly.
This is backwards compatible, will just raise fewer exceptions in naive user
code.
Improve code examples in hashlib cookie signing (GH-3562) (GH-3566)
The `blake2b` function does not take the `data` keyword argument.
The hex digest returned by sign was a string, whereas compare_digest expects bytes-like objects.
Typo fix: compare_digesty -> compare_digest

[3.6] bpo-31323: Fix reference leak in test_ssl (GH-3263) (#3538)

(cherry picked from commit 868710158910fa38e285ce0e6d50026e1d0b2a8c)
ProcessPoolShutdownTest.test_del_shutdown() now closes the call queue

* test_thread.test_forkinthread() now waits until the thread completes.

* Don't ignore RuntimeError anymore: since the commit 346cbd351ee0dd3ab9cb9f0e4cb625556707877e (bpo-16500,
os.register_at_fork(), os.fork() cannot fail anymore with
RuntimeError.
* Replace 0.01 literal with a new POLL_SLEEP constant
* test_forkinthread(): test if os.fork() exists rather than testing
the platform.

* Explicitly call shutdown(wait=True) on executors to wait until all
threads complete to prevent side effects between tests.
* Fix test_loop_self_reading_exception(): don't mock loop.close().
Previously, the original close() method was called rather than the
mock, because how set_event_loop() registered loop.close().

[3.6] bpo-27099: IDLE - Convert built-in extensions to regular features (GH-2494) (#3487)
About 10 IDLE features were implemented as supposedly optional
extensions. Their different behavior could be confusing or worse for
users and not good for maintenance. Hence the conversion.
The main difference for users is that user configurable key bindings
for builtin features are now handled uniformly. Now, editing a binding
in a keyset only affects its value in the keyset. All bindings are
defined together in the system-specific default keysets in config-
extensions.def. All custom keysets are saved as a whole in config-
extension.cfg. All take effect as soon as one clicks Apply or Ok.
The affected events are '<<force-open-completions>>', '<<expand-word>>',
'<<force-open-calltip>>', '<<flash-paren>>', '<<format-paragraph>>',
'<<run-module>>', '<<check-module>>', and '<<zoom-height>>'. Any
(global) customizations made before 3.6.3 will not affect their keyset-
specific customization after 3.6.3. and vice versa.

TLS 1.3 introduces a new, distinct set of cipher suites. The TLS 1.3
cipher suites don't overlap with cipher suites from TLS 1.2 and earlier.
Since Python sets its own set of permitted ciphers, TLS 1.3 handshake
will fail as soon as OpenSSL 1.1.1 is released. Let's enable the common
AES-GCM and ChaCha20 suites.
Additionally the flag OP_NO_TLSv1_3 is added. It defaults to 0 (no op) with
OpenSSL prior to 1.1.1. This allows applications to opt-out from TLS 1.3
now.
[3.6] bpo-31036: Allow sphinx and blurb to be found automatically (GH-3440) (#3441)
Rather than requiring the path to blurb and/or sphinx-build to be specified to the make rule, enhance the Doc/Makefile to look for each first in a virtual environment created by make venv and, if not found, look on the normal process PATH. This allows the Doc/Makefile to take advantage of an installed spinx-build or blurb and, thus, do the right thing most of the time. Also, make the directory for the venv be configurable and document the `make venv` target.
