Arjun Shankar 244c404ae8 malloc: Add threaded variants of single-threaded malloc tests ...

Single-threaded malloc tests exercise only the SINGLE_THREAD_P paths in
the malloc implementation.  This commit runs variants of these tests in
a multi-threaded environment in order to exercise the alternate code
paths in the same test scenarios, thus potentially improving coverage.

$(test)-threaded-main and $(test)-threaded-worker variants are
introduced for most single-threaded malloc tests (with a small number of
exceptions).  The -main variants run the base test in a main thread
while the test environment has an alternate thread running, whereas the
-worker variants run the test in an alternate thread while the main
thread waits on it.

The tests themselves are unmodified, and the change is accomplished by
using -DTEST_IN_THREAD at compile time, which instructs support/
infrastructure to run the test while an alternate thread waits on it.
