versions of the thread lock functions to determine at runtime if a lock is needed) to OMPI_ENABLE_PROGRESS_THREADS instead of OMPI_HAVE_THREAD_SUPPORT. Opal only starts a thread when OMPI_ENABLE_PROGRESS_THREADS is enabled, and ORTE never really starts a thread that requires special locking considerations. MPI_INIT would set opal_uses_threads to true if thread level was greater than MPI_THREAD_SINGLE, but it would never decreast the value of opal_uses_threads, meaning that we always enabled all that locking if we did a threaded build, which isn't neccessary. Now we do locking iff progress threads are enabled OR thread level is above MPI_THREAD_SINGLE. This commit was SVN r11390.
