42bf7466fc This isn't as big a change as it appears - a change in one place caused a whole bunch of files to require updated #include's due to some arcane linkage. Rework the orte_wait code to reflect the introduction of the state machine. If we are in cleanup mode and just want to kill all our local children, then there is no reason to be polite about it as that introduces *very* long delays at scale. Just kill the procs and move on.

3f04d50cb0 Per the ticket, resolve our handling of overload conditions to provide a more consistent response. If we are overloaded (i.e., attempting to bind more processes to a location than the number of cpus under that location), then we consider the following conditions: 
(a) default binding policy is in effect. In this case, we will emit a
warning and default to not binding unless the user provided the
"oversubscribe" or "overload" modifier to the "bind-to" option.

(b) user-specified binding policy is in effect. In this case, we will
error out unless the user provided the "oversubscribe" or "overload"
modifier to the "bind-to" option as we cannot meet the directive.

Either "bind-to" modifier (oversubscribe or overload) will be accepted for
now - in 1.9, we will deprecate the "overload" term in favor of
"oversubscribe".

Also added the ability to accept a --bind-to modifier without specifying the binding policy itself so a user can specify overload-allowed with the default policy.

Closes trac:4345

06dbfa3098 Make the cpus-per-proc equivalent a little more intuitive: 
* allow users to specify just a modifier for map-by instead of requiring that they also specify a policy. Thus, we now accept --map-by :pe=3 as indicating that we should use the default mapping policy, but bind 3 cpus/proc.

* if users specify a pe's/proc but no policy, default to --map-by NUMA to ensure we have access to multiple cpus for the request. This won't guarantee we have access to enough to meet the request, but gives us a chance. In addition, we know that binding a proc to multiple cpus will work best if those cpus are all in the same NUMA, so this provides some degree of optimized behavior.

Per a request from Jeff, define "oversubscribe" for binding as a synonym for the "overload" modifier.

638c24f655 Correct the bind-in-place algorithm to better handle comm_spawn. If the location identified by the mapper is already occupied by procs from another job, then we need to shift either right or left until we find an unoccupied location where we can be bound. If nothing is available, then check for the overload flag (and bind us in the original location if provided), or see if this was the default binding policy instead of one specified by the user - if so, then just don't bind this process.

e21bfeadcd Now that the BTLs are moving down to OPAL and becoming available to ORTE, there no longer is a need/desire to push performance in the OOB/TCP component. So we don't need multiple modules driving NICs in parallel, and can drop all the complicated distribution logic. Fall back to the simplified single module model, but retain the ability to run that module in its own progress thread if so directed. 
This should eliminate the connectivity issues that have been reported, and will make maintenance of this component much easier.

041b72b0cc plm/alps: better workaround for the noisy cray pmi implementation 
This commit is a slightly better workaround to prevent mesages of
the form:
[unset]:_pmi_alps_get_apid:alps_app_lli_put_request failed
[unset]:_pmi_alps_get_appLayout:pmi_alps_get_apid returned with error: Bad file descriptor

It works by completely disabling PMI in the application process when using
mpirun. This should not be an issue for any apps.

This commit fixes several leaks:

 - Both the oob/base and oob/tcp were leaking objects on their peer
   hash tables. Iterate on the hash tables and free any objects.

 - Leaked sent messages because of missing OBJ_RELEASE. I placed the
   release in ORTE_RML_SEND_COMPLETE to catch all the possible
   paths.

a8e2d6c3a6 The bulk of the remaining renaming changes, in one final glorious "blob". Thanks to Jeff for some help chasing down a few spots. Per chat with Jeff, we decided to cleanup a few things that were historical in nature: 
top_ompi_srcdir  ->  OMPI_TOP_SRCDIR
top_ompi_builddir -> OMPI_TOP_BUILDDIR

We also split the srcdir/builddir flags according to their local tree (e.g., OPAL_TOP_SRCDIR), and tied them all together in configure.ac. Renamed ompi_ignore and ompi_unignore to be opal_<foo> as these are agnostic markers.

Only thing left is ompilibdir being treated similar to what we dif for srcdir/builddir. Coming soon.
