Clarify that the level argument is used to determine whether to
perform absolute or relative imports: 0 is absolute, while a positive number
is the number of parent directories to search relative to the current module..

When PyGILState_Ensure() is called in a non-Python thread before
PyEval_InitThreads(), only call PyEval_InitThreads() after calling
PyThreadState_New() to fix a crash.

This isn't a real problem because if the file pointer is not NULL, the
string-related fields are never touched. But, it doesn't hurt to set the unused
fields to NULL.
bpo-31692, bpo-19527:
* Add a new PYTHONSHOWALLOCCOUNT environment variable, similar to
the Python 3 "-X showalloccount" option
* When Python is compiled with COUNT_ALLOCS, the new
PYTHONSHOWALLOCCOUNT environment variable now has to be set to dump
allocation counts into stderr on shutdown. Moreover, allocations
statistics are now dumped into stderr rather than stdout.
* Add @test.support.requires_type_collecting decorator: skip test if
COUNT_ALLOCS is defined
* Fix tests for COUNT_ALLOCS: decorate some methods with
@requires_type_collecting
* test_sys.test_objecttypes(): update object type when COUNT_ALLOCS
is defined
* [2.7] bpo-30765: Avoid blocking when PyThread_acquire_lock() is asked not to (GH-2403)
* bpo-30765: Avoid blocking when PyThread_acquire_lock() is asked not to lock
This is especially important if PyThread_acquire_lock() is called reentrantly
(for example from a signal handler).
* Update 2017-06-26-14-29-50.bpo-30765.Q5iBmf.rst
* Avoid core logic when taking the mutex failed.
(cherry picked from commit f84ac420c2)
* Remove test undef
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.
Issue #29188: Support glibc 2.24 on Linux: don't use getentropy() function but
read from /dev/urandom to get random bytes, for example in os.urandom(). On
Linux, getentropy() is implemented which getrandom() is blocking mode, whereas
os.urandom() should not block.
This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
to fix the grammar.
