Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes of multiple security
vulnerabilities including: CVE-2017-9233 (External entity infinite loop
DoS), CVE-2016-9063 (Integer overflow, re-fix), CVE-2016-0718 (Fix
regression bugs from 2.2.0's fix to CVE-2016-0718) and CVE-2012-0876
(Counter hash flooding with SipHash). Note: the CVE-2016-5300 (Use
os-specific entropy sources like getrandom) doesn't impact Python, since Python
already gets entropy from the OS to set the expat secret using
``XML_SetHashSalt()``.

For finer control of tracing behaviour when testing the interpreter, two new
frame attributes have been added to control the emission of particular trace

trace events.

Improve signal delivery.
Avoid using Py_AddPendingCall from signal handler, to avoid calling

The ``sys.path[0]`` initialization change for bpo-29139 caused a regression
by revealing an inconsistency in how sys.path is initialized when executing
``__main__`` from a zipfile, directory, or other import location. The
interpreter now consistently avoids ever adding the import location's parent
directory to ``sys.path``, and ensures no other ``sys.path`` entries are
inadvertently modified when inserting the import location named on the
command line.

Changed the implementation strategy for collections.namedtuple() to
substantially reduce the use of exec() in favor of precomputed methods. As a
result, the *verbose* parameter and *_source* attribute are no longer
supported. The benefits include 1) having a smaller memory footprint for
applications using multiple named tuples, 2) faster creation of the named
tuple class (approx 4x to 6x depending on how it is measured), and 3) minor
speed-ups for instance creation using __new__, _make, and _replace. (The
primary patch contributor is Jelle Zijlstra with further improvements by
INADA Naoki, Serhiy Storchaka, and Raymond Hettinger.)

There are a number of uninformative asserts in the `multiprocessing` module,
as noted in issue 5001. This change fixes two of the most potentially
problematic ones, since they are in error-reporting code, in the
`multiprocessing.managers.convert_to_error` function. (It also makes more
informative a ValueError message.) The only potentially problematic change
is that the AssertionError is now a TypeError; however, this should also
help distinguish it from an AssertionError being *reported* by the
function/its caller (such as in issue 31169). - Patch by Allen W. Smith

Tiny values (such as 1e-6) are valid non-zero values for setitimer(), which

therefore disabling the timer instead of (re-)scheduling it.

Convert IDLE's built-in 'extensions' to regular features.
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.
