[2.7] bpo-31692: Add PYTHONSHOWALLOCCOUNT env var (GH-3927)
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
