run: Set MALLOC_PERTURB_ to a random value.
MALLOC_PERTURB_ is a glibc feature which causes malloc to wipe memory before and after it is used, allowing both use-after-free and uninitialized reads to be detected with relatively little performance penalty: http://udrepper.livejournal.com/11429.html?nojs=1 Modify the ./run script so that it always sets this. We were already using MALLOC_PERTURB_ in most tests. Since ./run is now setting this, we can remove it from individual Makefiles. Most TESTS_ENVIRONMENT will now simply look like this: TESTS_ENVIRONMENT = $(top_builddir)/run --test
