The rdmacm event handler has no way of reporting fatal errors to the upper
layers. By calling mca_btl_openib_endpoint_invoke_error in the rdmacm event
handler for the errors encountered, these errors can now be handled
appropriately.

Short version: remove opal_paffinity_alone and restore
mpi_paffinity_alone. ORTE makes various information available for the
MPI layer to decide what it wants to do in terms of processor
affinity.
Details:
* remove opal_paffinity_alone MCA param; restore mpi_paffinity_alone
MCA param
* move opal_paffinity_slot_list param registration to paffinity base
* ompi_mpi_init() calls opal_paffinity_base_slot_list_set(); if that
succeeds use that. If no slot list was set, see if
mpi_paffinity_alone was set. If so, bind this process to its Node
Local Rank (NLR). The NLR is the ORTE-maintained slot ID; if you
COMM_SPAWN to a host in this ORTE universe that already has procs
on it, the NLR for the new job will start at N (not 0). So this is
slightly better than mpi_paffinity_alone in the v1.2 series.
* If a slot list is specified *and* mpi_paffinity_alone is set, we
display an error and abort.
* Remove calls from rmaps/rank_file component to register and lookup
opal_paffinity mca params.
* Remove code in orte/odls that set affinities - instead, have them
just pass a slot_list if it exists.
* Cleanup the orte/odls code that determined
oversubscribed/want_processor as these were just opposites of each
other.

If IBCM was explicitly specified with exclude/include parameter,
OpenIB BTL will enable verbose report for "/dev/infiniband/ucm" error,
other way the error will not be reported.
This commit was SVN r18868.
Lenny and I went back and forth on whether we should simply register
another "mpi_paffinity_alone" MCA param and then try to figure out
which one was set in ompi_mpi_init, but there was difficulty in
figuring out what to do. So it seemed like the Right Thing to do was
to implement what was committed in r18770; then we could tell where
MCA parameters were set from and you could do Better Things (this is
also useful in the openib BTL, where parameters can be set either via
MCA parameter or via an INI file).
But after that was done, it seemed only a few steps further to
actually implement two new features in the MCA params area:
* Synonyms (where one MCA param name is a synonym for another)
* Allow MCA params and/or their synonyms to be marked as "deprecated"
(printing out warnings if they are used)
These features have actually long been discussed/desired, and I had
some time in airports and airplanes recently where I could work in
this stuff on a standalone laptop. So I did it. :-)
This commit introduces these two new features, and then uses them to
register mpi_paffinity_alone as a non-deprecated synonym for
opal_paffinity_alone. A few other random points in this commit:
* Add a few error checks for conditions that were not checked before
* Correct some comments in mca_base_params.h
* Add a few comments in strategic places
* ompi_info now prints additional information:
* for any MCA parameter that has synonyms, it lists all the
synonyms
* synonyms are also output as 1st-class MCA params, but with an
additional attribute indicating that they have a "parent"
* all MCA param name (both "real" or "synonym") will output an
attribute indicating whether it is deprecated or not. A synonym
is deprecated if it iself is marked as deprecated (via the
mca_base_param_regist_syn() or mca_base_param_register_syn_name()
functions) or if its "parent" MCA parameter is deprecated

first to the trunk. So, here is the trunk checkin:
The call to orte_show_help() to notify truncation of the max_inline value
was missing the want_error_header boolean, which eventually results in
a SEGV. This change corrects the call with the bool set to true.

These are mostly long additions to comments to document what is going on and why, and how/where it may be revised in the future. Just a couple of small, but important, changes to the code itself.

see how the next gen panasas stuff does in terms of warnings; we can
always re-merge this later if we want to. It's just easier if we have
as little OMPI-specific code as possible (particularly when we know
that the panasas code has some big changes coming).

hierarch disables itself now if the pml module used is *not* ob1. The reason
is, that the multi-level hierarchy detection algorithm checks the names of the
btl modules used. In case there are no btl's, we would segfault.
Furthermore, three minor changes:
- the 2-level hierarchy detection is now the default (sm vs. everything else
in the world).
- add udapl to the list of protocols checked for by the multi-level hierarch detection
- some of the verbose statements of hierarch were inaccurate. Fixed those comments/messages.

With help from Brian, modify the ompi/proc/proc.c code to be more thread-safe. Remove the list operations from the ompi_proc_t constructor and destructor. Insert list appends to ompi_proc_init and ompi_proc_find_and_add as required, and protect those with thread locks. Let only the ompi_proc_finalize function actually remove objects from the ompi_proc_list.
Cleanup a few places where functions might return without unlocking a thread. Ensure the ompi_proc_world also does an OBJ_RETAIN so that the reference count on any subsequently released object is correct.

1. repair of the linear and direct routed modules
2. repair of the ompi/pubsub/orte module to correctly init routes to the ompi-server, and correctly handle failure to correctly parse the provided ompi-server URI
3. modification of orterun to accept both "file" and "FILE" for designating where the ompi-server URI is to be found - purely a convenience feature
4. resolution of a message ordering problem during the connect/accept handshake that allowed the "send-first" proc to attempt to send to the "recv-first" proc before the HNP had actually updated its routes.
Let this be a further reminder to all - message ordering is NOT guaranteed in the OOB
5. Repair the ompi/dpm/orte module to correctly init routes during connect/accept.
Reminder to all: messages sent to procs in another job family (i.e., started by a different mpirun) are ALWAYS routed through the respective HNPs. As per the comments in orte/routed, this is REQUIRED to maintain connect/accept (where only the root proc on each side is capable of init'ing the routes), allow communication between mpirun's using different routing modules, and to minimize connections on tools such as ompi-server. It is all taken care of "under the covers" by the OOB to ensure that a route back to the sender is maintained, even when the different mpirun's are using different routed modules.
6. corrections in the orte/odls to ensure proper identification of daemons participating in a dynamic launch
7. corrections in build/nidmap to support update of an existing nidmap during dynamic launch
8. corrected implementation of the update_arch function in the ESS, along with consolidation of a number of ESS operations into base functions for easier maintenance. The ability to support info from multiple jobs was added, although we don't currently do so - this will come later to support further fault recovery strategies
9. minor updates to several functions to remove unnecessary and/or no longer used variables and envar's, add some debugging output, etc.
10. addition of a new macro ORTE_PROC_IS_DAEMON that resolves to true if the provided proc is a daemon
There is still more cleanup to be done for efficiency, but this at least works.
Tested on single-node Mac, multi-node SLURM via odin. Tests included connect/accept, publish/lookup/unpublish, comm_spawn, comm_spawn_multiple, and singleton comm_spawn.
Fixes ticket #1256

* Move the passive side QP move to RTS to before we send the reply
(vs. sending it after we get the RTU). A lengthy comment explains
the need for this.
* Add some timers to the code for analyzing where time is spent.
* Clarify a few error messages.
* Currently have a loop around ib_cm_listen() because sometimes it
fails for seeminly no reason. Have pending e-mails in to Sean
Hefty to see if we can figure out why this is happening. Note that
the more MPI processes you add, the more likely this error is to
occur (e.g., ran 720 processes and it happens at least 50% of the
time). This makes IBCM somewhat unattractive for general use;
hopefully we can get a fix...
