Edgar Gabriel d93def71ea second part of the 'running out of cids problem', this time focusing on what
happens when hierarch is used. . Two major items:
 - modify the comm_activate step to take an additional argument, indicating
 whether the new communicatio has to go through the collective selection
 step. This is not required sometimes (e.g. when a process calls
 MPI_COMM_SPLIT with color=MPI_UNDEFINED), and contributed significantly to
 the exhaustion of cids.
 - when freeing a communicator, check whether we can reuse the block of cids
 assigned to that comm. This only works if the current front of the cid
 assignment (cid_block_start) is right ater the block of cids assigned to this
 comm.
