malloc: Test various special cases related to allocation failures
This test case exercises unusual code paths in allocation functions, related to allocation failures. Specifically, the test can reveal the following bugs: (a) calloc returns non-zero memory on fallback to sysmalloc. (b) calloc can self-deadlock because it fails to release the arena lock on certain allocation failures. (c) pvalloc can dereference a NULL arena pointer. (a) and (b) appear specific to a faulty downstream backport. (c) was fixed as part of commit 10ad46bc6526edc5c7afcc57112da96917ff3629. The test for (a) was inspired by a reproducer supplied by Jeff Layton.
