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
rest of the code base.

Need to check the entire value instead of just the last N digits. Otherwise, "-host 15" will match nid0015, nid0115, and any other launch id ending in 15
It appears strtol can return either a NULL or a zero-length string, so check for both cases

Fix static port wireup by recording the TCP port mpirun is using and correctly passing the regex of hosts to the daemons. Do a better job of closing sockets on failed connection attempts. Correctly identify the remote host in the associated error message.
Fix partial allocation operations by not attempting to set #slots on nodes that were not used, and thus don't have a daemon or topology assigned to them

Add more specific error messages so the cause of a messaging problem is a little clearer. Remove some stale code. Ensure we stop trying to send a message after a few times.

Given that we only set OOB contact info from inside of events, or before we begin threaded operations (e.g., in the ess), allow set_contact_info to directly update the oob/base framework globals.
Correct the nidmap regex decompression routine.
Ensure that rank=1 daemon always sends back its topology as this is the most common use-case.

Samples are taken after MPI_Init, and then again after MPI_Barrier. This allows the user to see memory consumption caused by add_procs, as well as any modex contribution from forming connections if pmix_base_async_modex is given.
Using the probe simply involves executing it via mpirun, with however many copies you want per node. Example:
$ mpirun -npernode 2 ./mpi_memprobe
Sampling memory usage after MPI_Init

Note that the client value on node rhc001 is larger - this is where rank=0 is housed, and apparently it gets a larger footprint for some reason.

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.
add the option to pass an alternate port to plm
for example
node0 port=2222
directs the plm (via the ORTE_NODE_PORT) attribute to use
the non default port 2222 (e.g. ssh -p 2222 node0 ...)
Multiple conduits can exist at the same time, and can even point to the same base transport. Each conduit can have its own characteristics (e.g., flow control) based on the info keys provided to the "open_conduit" call. For ease during the transition period, the "legacy" RML interfaces remain as wrappers over the new conduit-based APIs using a default conduit opened during orte_init - this default conduit is tied to the OOB framework so that current behaviors are preserved. Once the transition has been completed, a one-time cleanup will be done to update all RML calls to the new APIs and the "legacy" interfaces will be deleted.
While we are at it: Remove oob/usock component to eliminate the TMPDIR length problem - get all working, including oob_stress
