Python 2 never checked for I/O error when reading .py files and
thus could mistake an I/O error for EOF and create incorrect .pyc
files.
This adds an check for this and aborts on an error.
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
daemon threads run while the interpreter is shutting down; instead,
these threads are now killed when they try to take the GIL), as it seems
to break some existing code.
environment variable, to provide an opt-in way to protect against denial of
service attacks due to hash collisions within the dict and set types. Patch
by David Malcolm, based on work by Victor Stinner.

........
* crashes on memory allocation failure found with failmalloc
* memory leaks found with valgrind
* compiler warnings in opt mode which would lead to invalid memory reads
* problem using wrong name in decimal module reported by pychecker
Update the valgrind suppressions file with new leaks that are small/one-time
leaks we don't care about (ie, they are too hard to fix).

At least some of these fixes should probably be backported to 2.5.
