more:
- Remove OPAL_ENABLE_MULTI_THREADS, since it didn't really do anything
correctly. Opal always has threads enabled at this point.
- Remove OMPI_ENABLE_PROGRESS_THREADS, since this hasn't worked in
8 years and it has performance issues we'll never be able to
overcome. Note that we have plans for re-adding async progress, using
a hybrid protocol of async and sync sends.
- OMPI_ENABLE_THREAD_MULTIPLE now determines whether the thread lock
macros do the check or not.
- Condition variables are ALWAYS polling right now, which fixes the thread
live-lock currently found when THREAD_MULTIPLE is turned on.
