Fixes scoll_basic failures with shmem_verifier, caused by recent changes
in handling of zero-size collectives.
- Check for zero-size length only for fixed size collect (shmem_fcollect),
but not for variable-size collect (shmem_collect)
- Add 'nlong_type' parameter to internal broadcast function, to indicate
whether the 'nlong' parameter is valid on non-root PEs, since it's
used by shmem_collect algorithm. Before this change, some components
assumed it's true (scoll_mpi) while others assumed it's false
(scoll_basic).
- In scoll_basic, if nlong_type==false, do not exit if nlong==0, since
this parameter may not be the same on all PEs.
- In scoll_mpi, fallback to scoll_basic if nlong_type==false, since MPI
requires the 'count' argument of MPI_Bcast to be valid on all ranks.

- Use opal hash table instead of list for group lookup.
- Code cleanup/refactoring. Group cache is now a part
of the proc_group.

(http://www.open-mpi.org/community/lists/devel/2013/09/12889.php), I
renamed all "f77" and "f90" directory/file names to "fortran"
(including removing shmemf77 / shmemf90 wrapper compilers and
replacing them with "shmemfort").
2. Fixed several Fortran coding errors.
3. Removed lots of old/stale comments that were clearly the result of
copying from the OMPI layer and then not cleaning up afterwards (i.e.,
the comments were wholly inaccurate in the oshmem layer).
4. Removed both redundant and harmful code from oshmem_config.h.in.
5. Temporarily slave building the oshmem Fortran bindings to
--enable-mpi-fortran. This doesn't seem like a good long-term
solution, but at least you can now build all Fortran bindings (MPI +
oshmem) or not. *** SEE MY NOTE IN config/oshmem_configure_options.m4
FOR WORK THAT STILL NEEDS TO BE DONE!
