single threaded builds. In its default configuration, all this does
is ensure that there's at least a good chance of threads building
based on non-threaded development (since the variable names will be
checked). There is also code to make sure that a "mutex" is never
"double locked" when using the conditional macro mutex operations.
This is off by default because there are a number of places in both
ORTE and OMPI where this alarm spews mega bytes of errors on a
simple test. So we have some work to do on our path towards
thread support.
Also removed the macro versions of the non-conditional thread locks,
as the only places they were used, the author of the code intended
to use the conditional thread locks. So now you have upper-case
macros for conditional thread locks and lowercase functions for
non-conditional locks. Simple, right? :).

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.

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)
