7b91f8baff Cleanup and fix bugs in the MPI dynamics section. Modify the dpm API so it properly takes ports instead of process names (as correctly identified by Aurelien). Fix race conditions in the use of ompi-server. Fix incompatibilities between the mpi bindings and the dpm implemenation that could cause segfaults due to uninitialized memory. 
Fix the ompi-server -h cmd line option so it actually tells you something!

Add two new testing codes to the orte/test/mpi area: accept and connect.

20473bfda2 on incoming connections, compare with every possible source address. 
Rational (taken from the code):

    /* This is PITA. We never know which source address an 
    * incoming/outgoing packet will have, so even with 
    * btl_tcp_if_include/exclude on the remote end, we 
    * might get a different source address. 
    * 
    * If this address isn't included in btl_proc->proc_addrs, 
    * we would erroneously drop the connection 
    */ 

merge -r18165:18167 to the trunk.

e981a259bb btl_tcp_disable_family=4 and btl_tcp_disable_family=6 are mutually

0ddfff4ffe Added new oob-tcp parameter oob_tcp_disable_family. 
Like btl_tcp_disable_family, this parameter more or less disables
a whole address family. Though the sockets are still created, the
corresponding information isn't added to the connection strings.

Likewise, we don't try to connect to addresses matching the disabled
address family.

This is particularly important for multidomain clusters, where IPv4 is
oftenly filtered (firewalled), sometimes by simply dropping the packets
instead of rejecting them (thus causing a connection timeout instead of
a quick "no route to host").

7c7304466c Add a binomial tree-based launch to ssh, turned "on" only when the plm_rsh_tree_spawned mca param is set to a non-zero value. This probably isn't a very optimized capability, but it does execute a tree-based launch that may scale better than linear at high node counts. 
Add the daemon map capability to the ODLS to create and save a map of daemon vpid vs nodename from the launch message.

Cleanup a few places in the base plm launch support where we didn't adequately protect rml recv's from potentially executing sends.

08ead87604 Potential double free of locks 
mca_btl_openib_endpoint_post_rr_nolock is freeing the endpoint lock on
the error case, but most/all of the functions calling this free the lock
regardless of its error case.  Thus resulting is a double free of the
lock.

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...

4964434205 reverting commit 18122, since the commit was executed accidentally in the 
wring directory. The UH copyrights do belong into this file (i.e. because of
the fix which is in the 1.2 branch, the UH copyright notes are in the header
there alreary), but I want to have the proper log for that.

5989fa570c Sorry, previous commit was in the wrong directory. This is the real fix (have 
to undo 1822).

The verification of recvcount==0 and rank = root was braking
inter-communicator scatter, since the root (root==MPI_ROOT) might very well
have recvcount=0. The same fix has been applied to gather.c just the other way
round. 
 
Fixes the bug reported on the mainling list by Martin Audet. If there is a
1.2.7 this fix might be worthwhile porting it over.

Please note, that while the test works now for basic and for inter, we get a
0byte malloc warning from the inter module, which we still have to fix in a
separate patch.

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.
