Brian Barrett b56c8c3a66 * Default the value of opal_uses_threads (which is used by the macro
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.
