e6b3e4178d drd/tests/pth_barrier: Reduce stack usage

5800c7271c Check return code of pthread_create and bail out if 
the function failed. This helps on systems which don't
have lots of memory.
Suggested by Christian Borntraeger.

93234dd711 drd: Make racing pthread_barrier_wait() calls trigger an error message instead 
of an assertion failure. Also, make barrier tracing output more detailed.

ab40e94dad drd: Fix a race condition in the barrier implementation that could result in false positives. 
What could occur before this fix is:
- The pthread_barrier() call in a first thread finishes.
- Another thread invokes pthread_join() on that thread, causing the information
  associated with that thread to be removed from the barrier object.
- The pthread_barrier() call in another thread finishes. Because some
  thread information has already been removed from the barrier object, the
  per-thread vector clock "last" won't be computed correctly by
  DRD_(barrier_post_wait)().
- Because of the above false positives could be reported.

This resulted in sporadic failure of the drd/tests/matinv regression test, and
should now be fixed.

eea9337891 The pthread.h on Android has no definition for pthread_rwlock_t, which 
makes the associated intercepts in Helgrind and DRD un-compilable.
Add a configure test for it, and use them to guard the aforementioned
intercepts.

9a36fe677e Get rid of the remaining "set but not used" warnings reported by gcc 4.6 by 
swapping the roles of the VALGRIND_DO_CLIENT_REQUEST() and
VALGRIND_DO_CLIENT_REQUEST_EXPR() macros. Also, many __attribute__((unused))
declarations on variables have been eliminated. Closes #269778.

Note: so far this patch has been tested on x86/Linux, amd64/Linux and
ppc64/Linux but not yet on any other supported CPU/OS combination.
