If a message cannot be routed because the addressee isn't yet known, then the message is held on a queue in the RML for a period of time (currently set to 500 millisec). At the end of that time, we pop the message from the list and attempt to send it again. This action requires that we convert the header back to
network-byte-order before calling the OOB.
If the message still cannot be routed, we put the message back on the list and reset the timer. However, since we are going to convert the header when it com
es off of the list, we have to ntoh it before putting it back on the list so it all comes out right. This step was missing.
Thus, the problem only showed up relatively rarely because a message would have to be pushed onto the queue at least twice for the problem to surface.
This should fix a specific ticket (1389), but we will wait to see the results of MTT runs to verify. Note that we really don't know why a message is rattling around in the RML for so long, especially since this all seems to be happening during finalize, so this could cause mpirun to hang. Or it could simply trash the message and exit cleanly. Shall be interesting to see!

Provide support for four MPIR extensions that allow specification of debugger daemon executable, argv for the debugger daemon, whether or not to forward debugger daemon IO, and whether or not debugger daemon will piggy-back on ORTE OOB network. Last is not yet implemented.
No change in behavior or operation occurs unless (a) the debugger specifically utilizes the extensions and, for co-locate while running, the user specifically enables the capability via an MCA param. Two of the MPIR extensions supported here are used in a widely-used debugger for a large-scale installation. The other two extensions are new and being utilized in prototype work by several debuggers for possible future release.

* Make the creation of the build dir for the man pages a bit more
robust (thanks to suggestions from Ralf W.).
* Only distribute the .Xin files, not the .X man pages themselves.
* Make the .X files depend on opal_config.h so that if you re-run
configure and change opal_config.h (e.g., a new version), the man
pages should get rebuilt.
* Man pages are now cleaned with "distclean", not "maintainer-clean".
* Fix a typo in opal_crs.7in.
* Udpate make_dist_tarball to update "date" in the VERSION file.
* Make make_dist_tarball a bit friendlier to hg checkouts.

- Move up the __opal_attribute_noreturn__ information
- Actually make it known outside in ess.h
- Additionally allow printf-type checking

This system is "off" by default and only operates upon specific directive for selection of a notifier component. At the moment, the only available component will write an error message to the syslog.

This needs some soak time to ensure we haven't opened any race conditions. I tried to loop everything in the shutdown procedure through that trigger event call to ensure it all goes through the one-time locks as it did before so that someone hitting ctrl-c when we are already shutting down shouldn't cause problems. Just want to let people use it for awhile to verify.

Since OMPI allows mpirun to default to the local node, and since users want to retain the option to co-locate procs with mpirun, we needed another param to block this error case.

Standardize the handling of the orte launch agent option across PLMs. This has been a consistent complaint I have received - each PLM would register its own MCA param to get input on the launch agent for remote nodes (in fact, one or two didn't, but most did). This would then get handled in various and contradictory ways.
Some PLMs would accept only a one-word input. Others accepted multi-word args such as "valgrind orted", but then some would error by putting any prefix specified on the cmd line in front of the incorrect argument.
For example, while using the rsh launcher, if you specified "valgrind orted" as your launch agent and had "--prefix foo" on you cmd line, you would attempt to execute "ssh foo/valgrind orted" - which obviously wouldn't work.
This was all -very- confusing to users, who had to know which PLM was being used so they could even set the right mca param in the first place! And since we don't warn about non-recognized or non-used mca params, half of the time they would wind up not doing what they thought they were telling us to do.
To solve this problem, we did the following:
1. removed all mca params from the individual plms for the launch agent
2. added a new mca param "orte_launch_agent" for this purpose. To further simplify for users, this comes with a new cmd line option "--launch-agent" that can take a multi-word string argument. The value of the param defaults to "orted".
3. added a PLM base function that processes the orte_launch_agent value and adds the contents to a provided argv array. This can subsequently be harvested at-will to handle multi-word values
4. modified the PLMs to use this new function. All the PLMs except for the rsh PLM required very minor change - just called the function and moved on. The rsh PLM required much larger changes as - because of the rsh/ssh cmd line limitations - we had to correctly prepend any provided prefix to the correct argv entry.
5. added a new opal_argv_join_range function that allows the caller to "join" argv entries between two specified indices
Please let me know of any problems. I tried to make this as clean as possible, but cannot compile all PLMs to ensure all is correct.

Mpirun - and the orteds - were doing their best to whack all session dirs on their nodes just in case there was something lingering due to an abnormal termination. Unfortunately, they were -too- good at it. They were whacking all session directories under the user's name, even those from other mpiruns!
This adds another layer to the session dir tree so that we can denote which jobs come from our own job family, and restricts the cleanup operation to only session dirs from within our own job family. So we'll still cleanup anything due to our own mpirun, but won't whack any other mpirun from this user.
Call it being polite...

* we'll convert the rest over time (I'll file a ticket once all
this is committed)
* add 32 bytes of "reserved" space to the end of mca_base_component_t
and mca_base_component_data_2_0_0_t to make future upgrades
[slightly] easier
* new mca_base_component_t size: 196 bytes
* new mca_base_component_data_2_0_0_t size: 36 bytes

* all MCA frameworks versions bumped to v2.0
* be a little more explicit about version numbers in the MCA base
* add big comment in mca.h about versioning philosophy

Cleanup the logic in the odls for when processes terminate. It turns out that we were only going through the kill_proc logic once instead of looping over all local children when we ordered a daemon to kill its local procs. This went unnoticed for some time as for most systems the local procs were terminated anyway when the daemon terminated due to the parent/child relationship.
Solaris is apparently different - the children are not automatically terminated when the parent dies. As a result, it acts as a detector for this bug.
Mucho thanks to Rolf V. for his help in debugging - and to IM for letting me follow his gdb progress in quasi real-time!

Fix a few bugs in the mappers:
1. Ensure that bynode with no -np fills all available slots - it just does so with the ranks set bynode instead of byslot
2. fix --nolocal behavior so it works correctly in all cases. We still have to test the host's name using opal_ifislocal in the mapper because the name returned by gethostname to orte_process_info.hostname can be an FQDN, but a hostfile may contain a non-FQDN version.
3. Add missing --nolocal logic to the seq mapper
Oversubscribed mapping seemed to be working okay without repair, so I couldn't verify my own bug report in that regard.
Also included are some preliminary changes to support the modified hostfile behavior, which will be committed shortly:
1. removed the totally useless "allocate" field in the orte_node_t object since every node is automatically allocated for use - and everything ignored the field anyway
2. correctly initialize the slots_alloc field when the allocation is read
This commit was SVN r19030.
Modify the odls to remove a (size_t) typecast in front of the num_processors variable just in case it is returned negative. This usually is accompanied by an opal_error, so this shouldn't make any difference - but it is more technically correct.

Fixed allocation of all ranks when using RANKFILE, but not all ranks assigned
Aborting if using RANKFILE, but np wasn't specified a little earlier

1. add a new API delete_route(orte_process_name_t*) to delete the specified proc from the routing table

can have a pub_endpoint and a sub_endpoint that are not equal but go
to the same place (fd). I didn't think that that was possible. :-\
So just use a bool to track whether we have forwarded the fragment at
all; if we have, then don't forward to the sub_endpoint.
IOF is going to be re-written for v1.4.
