Cleanup the way we look for matching OFI addresses by using the opal_net_samenetwork helper function. This now works for multi-network environments, but only using the socket provider

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 Remove the stale lama component as it is now very out-of-date.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

Fix the --nolocal option by ensuring we always check/remove the HNP from the list of available nodes if the flag is set
Ensure that the HNP node is included as available when nothing else is given

On unmanaged allocations, we need to update the total_slots_allocated once the daemons have been launched and "discovered" their topology

Do not pass param file MCA params if the user has requested that no param files be read - required when trying to avoid launch time penalties from large numbers of processes reading default param files. The daemon picks them up and passes them along anyway, so it isn't clear what value we gain from having them all read the defaults

This PR renames the common library for OFI libfabric from
libfabric to ofi. There are a number of reasons this
is good to do:
1) its shorter and replaces 9 characters with three for
function names for what may eventually be a fairly extensive interface
2) OFI is the term used for MTL and RML components that use
the OFI libfabric interface
3) A planned OSC component will also use the OFI term.
4) Other HPC libraries that can use OFI libfabric tend to use
the term "ofi" internally and also in their configure options
relevant to OFI libfabric (i.e. MPICH/CH4, Intel MPI, Sandia SHMEM)
There seem to be comments in places in the Open MPI source
code that indicate that this common library will be going away.
Far from it as we will want to be able to share things like
AV objects between OMPI and possibly OSHMEM components that
use the OFI libfabric interface.
This PR also adds a synonym to the --with-libfabric(-libdir)
configury options: --with-ofi and with-ofi-libdir.

This commit recategorizes several mpirun arguments,
and moves the information for mpirun --help arguments
to the bottom of the general help message. I also
added the OPAL_CMD_LINE_OTYPE field to two commands
that were missed initially because they were not
in the same area as the others.
