Move the fake usnic IBV provider out of common/verbs and into a new
common/verbs_usnic component that is always statically linked into
libopen-pal. The fake provider is registered with libibverbs at run
time, but there is no *un*register IBV API. Hence, we can't let the
code containing this provider be dlclosed -- which means it needs to
be statically linked into libopen-pal.
Fixesopen-mpi/ompi#1060.
Bring Slurm PMI-1 component online
Bring the s2 component online
Little cleanup - let the various PMIx modules set the process name during init, and then just raise it up to the ORTE level. Required as the different PMI environments all pass the jobid in different ways.
Bring the OMPI pubsub/pmi component online
Get comm_spawn working again
Ensure we always provide a cpuset, even if it is NULL
pmix/cray: adjust cray pmix component for pmix
Make changes so cray pmix can work within the integrated
ompi/pmix framework.
Bring singletons back online. Implement the comm_spawn operation using pmix - not tested yet
Cleanup comm_spawn - procs now starting, error in connect_accept
Complete integration
This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).

CID 1269865 Resource leak (RESOURCE_LEAK)
Slightly refactored the code to remove extra goto statements and
ensure the if_include_list and if_exclude_list are actually released
on success.

Only install the fake usnic libibverbs driver when there are actually
usnic kernel devices present. This prevents some run-time weirdness
on the Cray verbs emulation environment, where apparently
ibv_register_driver() either is not implemented or does not work
properly.
This is likely short-lived: now that libfabric has a 1.0.0 release
available, the embedded libfabric may disappear from the OMPI tree
sometime soon. However, we still need it for the time being...
The ompi libfabric/Makefile.am to build the libmca_component_libfabric
lib was missing a recently added psmx_eq.c in the list of source
files for the psm provider.
Fixes#569

libibverbs will complain to stderr if it sees device entries in
/sys/class/infiniband for which it has no userspace plugins.
The Cisco usNIC device no longer exports a verbs interface, thereby
causing libibverbs to emit this annoying stderr warning.
To avoid this, use the public ibv API to register a "fake" libibverbs
driver at run-time (right after we call ibv_fork_init(), but --
critically -- *before* we call ibv_get_device_list()). The purpose of
this driver is solely to convince libibverbs that there *is* a driver
for /sys/class/infininband/usnic_verbs devices. ...although this
driver will never return a valid ibv context (and therefore will never
be used).
