This commit fixes leaks of bml endpoints in finalize. A summary of the
bugs/fixes is below.
1) ompi_mpi_finalize used ompi_proc_all to get the list of procs but
never released the reference to them (ompi_proc_all called
OBJ_RETAIN on all the procs returned). When calling del_procs at
finalize it should suffice to call ompi_proc_world which does not
increment the reference count.
2) del_procs is called BEFORE ompi_comm_finalize. This leaves the
references to the procs from calling the pml_add_comm
function. The fix is to reorder the calls to do omp_comm_finalize,
del_procs, pml_finalize instead of del_procs, pml_finalize,
ompi_comm_finalize.
3) The check in del_procs in r2 checked for a reference count of
1. This is incorrect. At this point there should be 2 references:
1 from ompi_proc, and another from the add_procs. The fix is to
change this check to look for a reference count of 22. This check
makes me extremely uncomforable as nothing will call del_procs if
the reference count of a procs is not 2 when del_procs is
called. Maybe there should be an assert since this is a developer
error IMHO.
