This required a little fiddling with a number of areas. Biggest problem was that it uncovered a potential for an infinite loop to be created in the registry. If a callback function modified the registry, the registry checked the triggers to see if anything had fired. Well, if the original callback was due to a trigger firing, that condition hadn't changed - so the trigger fired again....which caused the callback to be called, which modified the registry, which checked the triggers, etc. etc.
Triggers are now checked and then "flagged" as being "in process" so that the registry will NOT recheck that trigger until all callbacks have been processed. Tried doing this with subscriptions as well, but that caused a problem - when we release processes from a stagegate, they (at the moment) immediately place data on the registry that should cause a subscription to fire. Unfortunately, the system will just hang if that subscription doesn't get processed. So, I have left the subscription system alone - any callback function that modifies the registry in a fashion that will fire a subscription will indeed fire that subscription. We'll have to see if this causes problems - it shouldn't, but a careless user could lock things up if the callback generates a callback to itself.
Also fixed the code that placed a process' RML contact info on the registry to eliminate the leading '/' from the string.

- Added user help messages.
- Abstracted the internal commands, and the mechanism for
parsing and executing them.
- Cleaned up the command line parsing
- Some other misc. cleanup items.
Still much more work to do here, but should provide a more
intuitive interface for extending functionality in the
system.

more user friendly error messages.
Removed the "--version" command line option, since they should
get this from ompi_info [later to be orte_info].
If we find an invalid command line option print out the help
screen before exiting.

* add btl back into ompi_info. Since it now directly calls the
open/close, the missing symbol problems Ralph was seeing when ob1 is
ignored will not occur.

* 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

load a set of arguments to build OMPI. So you can do something like:
./configure --with-platform=redstorm
and automagically have all 10,000 arguments to configure required

* change all instances of sinclude to m4_include so that autogen
will properly fail if an .m4 file isn't included properly
