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.

The logs from this branch are much more descriptive than I will put
here (including a *really* long description from last night). Here's
the short version:
- fixed some broken implementations in ras and rmaps
- "orterun --host ..." now works and has clearly defined semantics
(this was the impetus for the branch and all these fixes -- LANL had
a requirement for --host to work for 1.0)
- there is still a little bit of cleanup left to do post-1.0 (we got
correct functionality for 1.0 -- we did not fix bad implementations
that still "work")
- rds/hostfile and ras/hostfile handshaking
- singleton node segment assignments in stage1
- remove the default hostfile (no need for it anymore with the
localhost ras component)
- clean up pls components to avoid duplicate ras mapping queries
- [possible] -bynode/-byslot being specific to a single app context

This allows the user to specify certain options to srun when an application
is launched with this PLS.
A useful example is the need to set the time to wait from when the first
process completes and when slurm kills remaining processes:
pls_slurm_args=--wait=1200

it to be an exit.
* Put the srun process (or what is about to become the srun process) in
it's own process group so that group-wide signals (such as the
SIGINT sent by hitting cntl-c in a shell) are not sent to the srun
process.
