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

This commit adds new timing feature that uses environment variables to
expose timing information. This allows easy access to this data (if
timing is enabled) from any other part of the application for the subsequent
postprocessing.
In particular this will be integrated with OMPI-level timing framework that
whill use MPI_Reduce functionality to provide more compact and easy-to use
information.
This commit also adds the example of usage of this framework by annotating
rte_init function. The result is not used anywhere for now. It will be
postprocessed in subsequent commits.
NOTE: that functionality is currently disabled untill it will be verified at runtime

onto the backend daemons. By default, let mpirun only pack the app_context
info and send that to the backend daemons where the mapping will
be done. This significantly reduces the computational time on mpirun as it isn't
running up/down the topology tree computing thousands of binding
locations, and it reduces the launch message to a very small number of
bytes.
When running -novm, fall back to the old way of doing things
where mpirun computes the entire map and binding, and then sends
the full info to the backend daemon.
Add a new cmd line option/mca param --fwd-mpirun-port that allows
mpirun to dynamically select a port, but then passes that back to
all the other daemons so they will use that port as a static port
for their own wireup. In this mode, we no longer "phone home" directly
to mpirun, but instead use the static port to wireup at daemon
start. We then use the routing tree to rollup the initial
launch report, and limit the number of open sockets on mpirun's node.

Per a prior commit, the presence of "hwloc.h" can cause ambiguity when
using --with-hwloc=external (i.e., whether to include
opal/mca/hwloc/hwloc.h or whether to include the system-installed
hwloc.h).
This commit:
1. Renames opal/mca/hwloc/hwloc.h to hwloc-internal.h.
2. Adds opal/mca/hwloc/autogen.options to tell autogen.pl to expect to
find hwloc-internal.h (instead of hwloc.h) in opal/mca/hwloc.
3. s@opal/mca/hwloc/hwloc.h@opal/mca/hwloc/hwloc-internal.h@g in the

Allow someone to specify the "pe=N" modifier to a mapping policy when N=1. This equates to just "bind-to core", but helps people who use a script to set the PE policy. Fix a bug where setting the binding policy left a lingering "if-supported" flag that shouldn't be there.

Revamp the event notification integration to rely on the PMIx event chaining and remove the duplicate chaining in OPAL. This ensures we get system-level events that target non-default handlers.
Restore the hostname entries for MPI-level error messages, but provide an MCA param (orte_hostname_cutoff) to remove them for large clusters where the memory footprint is problematic. Set the default at 1000 nodes in the job (not the allocation).

Still not completely done as we need a better way of tracking the routed module being used down in the OOB - e.g., when a peer drops connection, we want to remove that route from all conduits that (a) use the OOB and (b) are routed, but we don't want to remove it from an OFI conduit.

Ensure the returned exit status is non-zero if we fail to map
If no -np is given, but either -host and/or -hostfile was given, then error out with a message telling the user that this combination is not supported.
If -np is given, and -host is given with only one instance of each host, then default the #slots to the detected #pe's and enforce oversubscription rules.
If -np is given, and -host is given with more than one instance of a given host, then set the #slots for that host to the number of times it was given and enforce oversubscription rules. Alternatively, the #slots can be specified via "-host foo:N". I therefore believe that row #7 on Jeff's spreadsheet is incorrect.
With that one correction, this now passes all the given use-cases on that spreadsheet.
Make things behave under unmanaged allocations more like their managed cousins - if the #slots is given, then no-np shall fill things up.
