Jeff Squyres 583bf425c0 Fixes trac:1383:
Short version: remove opal_paffinity_alone and restore
mpi_paffinity_alone.  ORTE makes various information available for the
MPI layer to decide what it wants to do in terms of processor
affinity.

Details:

 * remove opal_paffinity_alone MCA param; restore mpi_paffinity_alone
   MCA param
 * move opal_paffinity_slot_list param registration to paffinity base
 * ompi_mpi_init() calls opal_paffinity_base_slot_list_set(); if that
   succeeds use that.  If no slot list was set, see if
   mpi_paffinity_alone was set.  If so, bind this process to its Node
   Local Rank (NLR).  The NLR is the ORTE-maintained slot ID; if you
   COMM_SPAWN to a host in this ORTE universe that already has procs
   on it, the NLR for the new job will start at N (not 0).  So this is
   slightly better than mpi_paffinity_alone in the v1.2 series.
 * If a slot list is specified *and* mpi_paffinity_alone is set, we
   display an error and abort.
 * Remove calls from rmaps/rank_file component to register and lookup
   opal_paffinity mca params. 
 * Remove code in orte/odls that set affinities - instead, have them
   just pass a slot_list if it exists. 
 * Cleanup the orte/odls code that determined
   oversubscribed/want_processor as these were just opposites of each
   other.
