If history-length is set in .inputrc, and the history file is double the
history size (or more), history_get(N) returns NULL, and python
segfaults. Fix that by checking for NULL return value.
It seems that the root cause is incorrect handling of bigger history in
readline, but Python should not segfault even if readline returns
unexpected value.
This issue affects only GNU readline. When using libedit emulation
system history size option does not work.
This is a backport of the actual fix from master without the test, since
the test depends on new run_pty() helper which is not available in 2.7.
* Add Windows support to test.support.SuppressCrashReport: call
SetErrorMode() and CrtSetReportMode().
* _testcapi: add CrtSetReportMode() and CrtSetReportFile() functions
and CRT_xxx and CRTDBG_xxx constants needed by SuppressCrashReport.

* bpo-29591: Upgrade Modules/expat to libexpat 2.2
* bpo-29591: Restore Python changes on expat
* bpo-29591: Remove expat config of unsupported platforms
Remove the configuration (Modules/expat/*config.h) of unsupported
platforms:
* Amiga
* MacOS Classic on PPC32
* Open Watcom
* bpo-29591: Remove useless XML_HAS_SET_HASH_SALT
The XML_HAS_SET_HASH_SALT define of Modules/expat/expat.h became
useless since our local expat copy was upgrade to expat 2.1 (it's now
expat 2.2.0).

* bpo-30614: testInitNonExistentFile() of test_bz2 leaks references
Extract the code of BZ2File_dealloc and create a new BZ2File_clear()
function. Call BZ2File_clear() in BZ2File_dealloc().
Define BZ2File_clear() as tp_clear.
Move the lock initialization before the "self->file =
PyObject_CallFunction" in BZ2File_init() and check the lock is not
created twice.
Call BZ2File_clear() in BZ2File_init() after the init of the lock

Fix after the review of Victor Stinner
Running Python with the -3 option now warns about regular expression
syntax that is invalid or has different semantic in Python 3
or will change the behavior in future Python versions.
Running Python with the -3 option now emits deprecation warnings for
getchildren() and getiterator() methods of the Element class in the
xml.etree.cElementTree module and when pass the html argument to
xml.etree.ElementTree.XMLParser().
Fixed a deprecation warning about the doctype() method of the
xml.etree.ElementTree.XMLParser class. Now it is emitted only when
define the doctype() method in the subclass of XMLParser.
Fixed a bug in the test_bug_200708_close test method. An EchoTarget
instance was incorrectly passed to XMLParser() as the html argument and
silently ignored.
Tests no longer failed when use the -m option for running only selected
test methods. Checking warnings now is more specific, warnings are
expected only when use deprecated features.
* bpo-30283: regrtest: add --testdir option
* bpo-30283: Backport _testcapi.raise_signal()
Function used by test_regrtest to simulate an interrupted unit test.
* bpo-30283: Backport test_regrtest from master
It was possible to get a core dump by using uninitialized
_json objects. Now __new__ methods create initialized objects.
__init__ methods are removed..
(cherry picked from commit 76a3e51a40)
Based on commit 5c4b0d063a by Ned
Deily, which is based on original patches by Brett Cannon and Steve
Dower.
Remove also the private _Py_svnversion() function and SVNVERSION
variable.
Note: Py_SubversionRevision() and Py_SubversionShortBranch() are
unchanged, they are part of the public API.
