Peter Dillinger e03d958b91 Clean up variables for temporary directory (#9961)
Summary:
Having all of TMPD, TMPDIR and TEST_TMPDIR as configuration
parameters is confusing. This change simplifies a number of things by
standardizing on TEST_TMPDIR, while still recognizing the old names
also. In detail:
* crash_test.mk also needs to use TEST_TMPDIR for crash test, so put in
shared common.mk (an upgrade of python.mk)
* Always exporting TEST_TMPDIR eliminates the need to propagate TMPD or
export TEST_TMPDIR in selective places.
* Use --tmpdir option to gnu_parallel so that it doesn't need TMPDIR
environment variable
* Remove obsolete parloop and parallel_check Makefile targets
* Remove undefined, unused function ResetTmpDirForDirectIO()
