7d34770456 further bugfixes. The hierarchy detection works now as far as I can see (even in unsymmetric sitations). Bcast and reduce work as well. Still to test: the code which generates new local leader communicators, in case the root of the operation is not yet part of the lleader comm.

ba163c611c checkpoint before moving to a real cluster. Most of the recoding should be 
done. This version also doesn't break ompi (at least if its not chosen :-) ).
New features compared to the version from last Thursday (where bcast and
reduce seemed to work in most scenarios):
- clearer internal infrastructure
- ability to handle all root processes with a (hopefully) minimal number of
local leader communicators.

f47c272986 Fix for the max-31-F90-symbol-limit problem: keep the interface names 
the same (since those are both mandated by MPI and <31 characters),
but change some of the back-end subroutine names so that they are <31
characters and therefore obey the F90 standard.  Remove an outdated /
useless (and confusing) script.

92429dc90f Fix for a problem Edgar and Jeff identified WRT PLS determining if we are 
oversubscribed on a node. And thus whether to call sched_yield or not.

The value of node->node_slots_inuse does not currently represent the number of
slots actually in use, at the moment. This is actually a bug in the RAS/RMAPS
base components, but the fix for that specific bug is bigger than we want to 
address at the moment (but will certianly do so in the near future).

Since we cannot trust this value, use the total number of mapped processes
(which was properly set by the RMAPS component upon mapping -- Just not 
properly propagated back to the registry's node segment) from the process 
mapping.

In addition to this change I cleaned up a couple of the debug messages. It
seems that TM and RSH are the only two directly effected by this. SLURM
would be if that section of code wasn't currently inactive, but put the fix
in for prosparity.

af9ccdf04a need to use get_first instead of get_begin since we don't want to execute 
this loop if "nodes" is an empty list. get_first, in this loop context, 
allows us to do just that, while get_begin doesn't.

This fixes a --host problem that appeared on the Linux PPC64 build.
