open/close, the missing symbol problems Ralph was seeing when ob1 is
ignored will not occur.

support in OMPI. Currently only enables/disables the architecture
sharing modex in ob1 pml.
* Add sds framework to ompi_info
* Figure out table ids to use for Portals BTL at configure time, since
we should use 30 & 31 on Red Storm, but the reference implementation
only supports 0-8.
* Some bug fixes in Portals UTCP sds
This commit was SVN r6650.
- only call sched_yield if it exists
- don't fail out if modex doens't work in ob1
- bunch of fixes for Portals BTL
- add cnos rml component
- add NULL gpr component (should only be used if replica AND proxy
fail to load)

* remove the recv fragment code, since it really isn't needed
* handle memory descriptor binding a bit more sanely, and use
thresholds so that Portals does the unlink for us, when it feels
like it.

* change all the opal_output_verbose calls in the critical path to
OPAL_OUTPUT_VERBOSE so that they are pre-processed out if debugging
is not enabled
* remove stub code

"run-time" api for the reference implementation.
* Make the non-modex utcp and redstorm compat code do the same things in
the same order

associated with the descriptor is ours again once the callback function
returns. Make it so - probably can optimize out some of the stuff I
did when I mistakenly thought the descriptor free() was called on the
passed descriptor
* Fix some dumb accounting errors with MD usage for unexpected receives

Fixed receive descriptor counts that limited mvapi and openib to 2 procs.

1. Modify the registry to eliminate redundant data copying for startup messages.
2. Revise the subscription/trigger system to avoid redundant storage of triggers and subscriptions. This dramatically reduces the search time when a registry action occurs - to illustrate the point, there are now only a handful of triggers on the system for each job. Before, there were a handful of triggers for each PROCESS in the job, all of which had to be checked every time something happened on the registry. This is much, much faster now.
3. Update all subscriptions to the new format. There are now "named" subscriptions - this allows you to "name" a subscription that all the processes will be using. The first one to hit the registry actually defines the subscription. From then on, any subsequent "subscribes" to the same name just cause that process to "attach" to the existing subscription. This keeps the number of subscriptions being tracked by the registry to a minimum, while ensuring that each process still gets notified.
4. Do the same for triggers.
Also fixed a duplicate subscription problem that was causing people to receive data equal to the number of processes times the data they should have received from a trigger/subscription. Sorry about that... :-( ...but it's all better now!
Uncovered a situation where the modex data seems to be getting entered on the registry a second time - the latter time coming after the compound command has been "fired", thereby causing all the subscriptions to fire. Asked Tim and Jeff to look into this.
Second phase of the changes will involve modifying the xcast system so that the same message gets sent to all processes. This will further reduce the message traffic, and - once we have a true "broadcast" version of xcast - really speed things up and improve scalability.
