This commit adds two new functions:
- ompi_proc_get_allocated - Returns all procs in the current job that
have already been allocated. This is used in init/finalize to
determine which procs to pass to add_procs/del_procs.
- ompi_proc_world_size - returns the number of processes in
MPI_COMM_WORLD. This may be removed in favor of callers just
looking at ompi_process_info.
The behavior of ompi_proc_world has been restored to return
ompi_proc_t's for all processes in the current job. The use of this
function is discouraged.
Code that was using ompi_proc_world() has been updated to make use of
the new functions to avoid the memory overhead of ompi_comm_world ().
