Ralph Castain 657e701c65 Add debug verbosity to the orte data server and pmix pub/lookup functions
Start updating the various mappers to the new procedure. Remove the stale lama component as it is now very out-of-date. Bring round_robin and PPR online, and modify the mindist component (but cannot test/debug it).

Remove unneeded test

Fix memory corruption by re-initializing variable to NULL in loop

Resolve the race condition identified by @ggouaillardet by resetting the
mapped flag within the same event where it was set. There is no need to
retain the flag beyond that point as it isn't used again.

Add a new job attribute ORTE_JOB_FULLY_DESCRIBED to indicate that all the job information (including locations and binding) is included in the launch message. Thus, the backend daemons do not need to do any map computation for the job. Use this for the seq, rankfile, and mindist mappers until someone decides to update them.

Note that this will maintain functionality, but means that users of those three mappers will see large launch messages and less performant scaling than those using the other mappers.

Have the mindist module add procs to the job's proc array as it is a fully described module

Protect the hnp-not-in-allocation case

Per path suggested by Gilles - protect the HNP node when it gets added in the absence of any other allocation or hostfile

/** @file:
*
* The Open RTE Resource MAPping Subsystem (RMAPS)
*
* The resource mapping subsystem is responsible for mapping processes
* to specific nodes/cpus within a given job. In many systems, this
* functionality will not be supported - the system will map processes
* wherever it chooses and does not allow the user to specify the
* mapping. RMAPS components, therefore, provide services for those
* systems that do permit such mappings.
*
* RMAPS checks the MCA parameters to see if a mapping algorithm has
* been specified. If the user selected a mapping algorithm, the
* indicated RMAPS component will take information from the registry
* to determine the number of applications/processes to be run, and
* the identified resources that have been allocated to this job. The
* selected RMAP component will then assign processes to resources
* according to its algorithm, with the results stored on the
* appropriate job segment - the assigned nodename for each process is
* stored in that respective process' container on the segment.
