Added another system-level test function for ORTE that just spins until terminated by a ctrl-c signal.
Modified orterun - added a couple of newlines to the output when abnormally terminating so the prompt always is on a new line.

than $(LN_S). This causes problems with with Windows and probably
elsewhere (re: #200). So use a slightly different trick to get the
right header selected for the MEMCPY and TIMER components.
* Using the same trick used to solve the AC_CONFIG_LINKS problem,
stop using a separate header file for direct calling in the
PML and MTL. This lets me remove some icky code in ompi_mca.m4
that was more fragile than I really liked.

keep the resulting tm_event_t that is generated because the back-end
TM library actually caches a bunch of stuff on it for internal
processing, and doesn't let go of it until tm_poll().
tm_event_t's are similar to (but slightly different than)
MPI_Requests: you can't do a million MPI_Isend()'s on a single
MPI_Request -- a) you need an array of MPI_Request's to fill and b)
you need to keep them around until all the requests have completed.

Jeff: this needs to be back-patched to our supported prior releases. I'll try to verify how far back we need to go - my initial guess is probably all of them

- change -no_oversubscribe to -nooversubscribe (to be similar to
-nolocal)
- Added text to orterun.1 describing slots and -nooversubscribe
Still need to add text about "mpirun a.out" functionality, and RHC
wants to make some minor edits, so committing for synchronization.

Since Jeff and I are going to a branch for T-bird, we have restored the trunk to its prior state to avoid any possibility of disturbing it.

Please report any abnormal behavior during launch, though, as we would like to understand what (if any) impact is seen. I couldn't see any on small jobs (the modulo functions render this number down pretty low).

- orte-clean.c : check to see if the base session directory is empty
and delete it if it is.
- orte_universe_exists.c : Fix a down stread problem resulting from
George's r10718 commit. Don't use the 'fulldirpath' since
that is no longer guarenteed to be the absolute path
to the session directory. Construct this value outside of that
function from the prefix and frontend vars.

Also put back in the 'Slots In Use' column as it is now working properly
per Ralphs recent ras commits. Still not sure what 'Slots Alloc' is meant
to represent, so left that as #if 0'd out for the moment.

Update the help text to report errors when not following that rule.
Also updated the RMAPS help text to reflect the reorganization of some of the round-robin code into the base.
The new functionality has been tested under Mac OS-X and on Odin using an MPI program. Both byslot and bynode mapping have been checked and verified. Operational support for other systems needs to be verified - I respectfully request people's help in doing so.

1. Modifies the RAS framework so it correctly stores and retrieves the actual slots in use, not just those that were allocated. Although the RAS node structure had storage for the number of slots in use, it turned out that the base function for storing and retrieving that information ignored what was in the field and simply set it equal to the number of slots allocated. This has now been fixed.
2. Modified the RMAPS framework so it updates the registry with the actual number of slots used by the mapping. Note that daemons are still NOT counted in this process as daemons are NOT mapped at this time. This will be fixed in 2.0, but will not be addressed in 1.x.
3. Added a new MCA parameter "rmaps_base_no_oversubscribe" that tells the system not to oversubscribe nodes even if the underlying environment permits it. The default is to oversubscribe if needed and the underlying environment permits it. I'm sure someone may argue "why would a user do that?", but it turns out that (looking ahead to dynamic resource reservations) sometimes users won't know how many nodes or slots they've been given in advance - this just allows them to say "hey, I'd rather not run if I didn't get enough".
4. Reorganizes the RMAPS framework to more easily support multiple components. A lot of the logic in the round_robin mapper was very valuable to any component - this has been moved to the base so others can take advantage of it.
5. Added a new test program "hello_nodename" - just does "hello_world" but also prints out the name of the node it is on.
6. Made the orte_ras_node_t object a full ORTE data type so it can more easily be copied, packed, etc. This proved helpful for the RMAPS code reorganization and might be of use elsewhere too.

using a pty for everything, which drops all buffered data on the floor when
close() is called on the daemon side, meaning EOF has some issues. Instead,
do the same thing we do for other starters that use the fork() pls -- use
a pipe/fifo for stdin and stderr and a pty for stdout. This is good enough
for what we need and avoids most of the issues with ptys.

Basically, the problem was that the allocator was grabbing everything on the cluster for which the user had access privilege. Thus, if a user had two sessions operable, each with its own allocation, mpirun in each session would grab both sets of nodes and use them. Not very polite.

* num_children should really be an int instead of size_t
since 'size_t' is not signed and num_children can (in rare cases)
drop below 0, and don't want it to roll around to MAX_INT or some
such.
* I figured out that this problem only happened to me because I use
the pls_fork_reap_timeout MCA parameter and thus the only time that
the code in pls_fork_module.c to waitpid is executed is if this is
not set to 0 (I had it set to 1 to give my procs time to exit). I
adjusted the loop from while{...} to do{...}while; so that it is
executed at least once for consistency.
* de-register the SIGCHILD callback for the pid before we attempt
to kill it, so that we don't leave the door open for both the
waitpids (the one in the callback, and the one in this function)
to race to see who can wait on the child.
* Move the 'thread release' to outside the for loop for a bit of an
optimization, and always set the value to 0 since we want to
finish after this function.
* Added a help message for the case when we can't send a kill()
signal to the process. Should never happen, but all is possible
in the wild wild west of HPC.

When we force an application to terminate (via CTRL-C to mpirun)
we send an out-of-band message to the orted to reap its children.
the fork PLS was doing an internal waitpid but never releasing or
updating the information and signaling the condition variable. So
the fork PLS callback for SIGCHLD registered with the event library
and this waitpid are in a bit of a race to 'waitpid' for the children.
Since the PLS callback was the only one that handled the signal properly
when it 'won' then things were great -- as in the normal termination case.
But when it 'lost' -- as in the abnormal termination case -- the orted
never received the proper signal that its children had gone away.
We want to preserve the internal fork PLS callback since it allows
for a timeout while waiting for the child, which the event library
won't do.
This allows both to exist, and behave properly.
This was introduced in r9068.
The ticket is still open since the orted's hang in other situations
still. This is a fix for one of the causes.

After seeing the uglyness that is removing directories in the
codebase I decided to push down this to the OPAL by extending the
opal/os_create_dirpath.(c|h) to contain some more functionality.
In this process I renamed 'os_create_dirpath' to 'os_dirpath' since it
is a bit more general now.
Added a few functions to:
- check if an directory is empty
- check to see if the access permissions are set correctly
- destroy the directory at the end of the dirpath
- By using a caller callback function (a la Perl, I believe)
for every file, the caller can have fine grained control over
whether a specific file is deleted or not.
This simplifies things a bit for orte_session_dir_(finalize|cleanup)
as it should no longer contain any of this functionality, but uses
these functions to do the work.
From the external perspective nothing has changed, from the
developer point of view we have some cleaner, more generic code.

Since we don't properly handle connecting/disconecting from multiple
universes, only connect to the first one (or the user specified one).
This is a bug that needs to be fixed, but involves some deep magic in
ORTE.
