851279fc9f Consolidate the daemon wireup message into the launch message. The daemons don't need their contact info prior to the launch message anyway. This not only eliminates a job-wide communication from the startup procedure, but it also resolves a race condition reported when operating across highly distributed (i.e., cross-country) networks. In such scenarios, it proved possible for a daemon to receive its launch message -before- it had received the contact info message, even though the latter had been sent first! 
This eliminates that problem...

22343e6e0b Given total lack of interest/support from the folks behind these environments, and the fact that we can now scale so well with our own daemons, it seems unlikely that we will be able to pursue direct and/or standalone launch in these environments. If that situation ever changes, it is easy enough to revive the effort since little had really been done to-date. 
Meantime, no reason to continue dragging these around.

dc2f88b9f0 Now that we have the daemon collectives, the unity routed module no longer needs the "hack" we inserted a week ago to tell the daemons how to talk directly to all the application procs. The modex and barrier messages flow cleanly across the daemons and are "dropped" into the procs where required. 
Add some insurance to make certain that the daemons' number of procs only gets updated when it absolutely is intended.

6166278e18 Improve the scalability of the modex operation and fix a bug reported by Tim P 
The bug was a race condition in the barrier operation that caused the barrier in MPI_Finalize to fail on very short programs.

Scalaiblity was improved by using the daemons to aggregate modex and barrier messages before sending them to the rank=0 proc. Improvement is proportional to ppn, of course, but there really wasn't a scaling problem at low ppn anyway. This modification also paves the way for better allgather operations since now all the data for each node is sitting at the daemon level, and the daemons are now aware that a collective operation on the OOB is underway (so they -can- participate in a collective of their own to support it).

Also added better diagnostics to map out the timing associated with MPI_Init - turned on by -mca orte_timing 1.

60d931217f Modify the routed framework to allow greater control/flexibility over response to lost routes and initial wireup of jobs as required by several soon-to-come new modules. 
Specifically, add two new APIs:

1. lost_route: allows the OOB to report that a connection has failed, thereby giving the routed module an opportunity to respond appropriately to its topology. Creating the API also allows each routed component to hold its own definition of "lifeline" - in some cases, this may be a single connection, but in others it may be multiple connections. Some modules may choose to re-route messaging if the lifeline or any other connection is lost, while others may choose to abort the job.

Both the tree and unity modules retain the current behavior and abort the job if the lifeline connection is lost, while ignoring other lost connections.

2. get_wireup_info: returns (in a provided buffer) info required to wireup connections for the specified job. Some routed modules do not need to return any info as they can wireup via alternative means, while some need to xchg data with their peers. If info is inserted into the buffer, the plm_base_launch_apps function will xcast the contents to the specified job.

The commit also removes the "lifeline" entry from the orte_process_info struct (and the associated ORTE_PROC_MY_LIFELINE definition) as the lifeline info is now contained within the respective routed module.

90107f3c14 Fix an issue with comm_spawn over who sent/recv first in the modex. The modex assumes that the first name on the list is the "root" that will serve as the allgather collector/distributor. The dpm was putting that entity last, which forced us to pre-inform the parent procs of the child proc's contact info since the parent was trying to send to the child. 
Clarify the setting of send_first in the mpi bindings (trivial, i know, but helpful)

Remove the extra xcast of child contact info to the parent job.
