There was a duplicated subnet check in the sender hash lookup routine.
This caused receivers to always fail the sender hash lookup if the
sender was in a different subnet, so the receiver would discard the
packet as though it were coming from a different job.

This functionality is required for routable UDP/IP usnic traffic.
Previously we would only setup endpoints for remote interfaces on the
same subnet as the current module's local interface. This behavior
still holds if two processes share any common subnets. However, if the
two processes only have no subnets in common then we assume that all
interfaces are reachable from all other interfaces and wire them up in a
1-1, randomly-matched order somewhat similarly to the "tcp" BTL's
behavior.
Only match in different subnets if we detect UDP support in the lower
layer.

This commit decouples OMPI deployment from the version(s) of the lower
layers of the stack by probing for UDP support.
Verbs applications assume a 40-byte header (there is no current
mechanism for querying payload offset). So to support a 42-byte UDP
header without causing existing applications like ibv_ud_pingpong or
older versions of OMPI to crash, we must inform libusnic_verbs that we
are aware of the nonstandard payload offset. We do this by overriding
the `transport_type` field of the device to be 42 before calling
`ibv_open_device`. If the library resets it to something else, then we
know the lower layers are UDP capable. Otherwise we use the older
custom-L2 format.
This necessitated some minor ugliness in common_verbs, but it's as tidy
as Jeff and I know how to make it right now.
This commit only adds support for UDP headers and connectivity over the
same L2 network, it does not touch routing or interface pairing.

so let's support them properly in Open MPI.
Added bonus: consolidating these checks up in
ompi_check_openfabrics.m4 allowed removing some custom checks and
AC_DEFINE's from the usnic configure.m4 script.
Also change the usnic/configure.m4 check for IBV_EVENT_GID_CHANGE to

r of slots remaing to be assigned being only one/node. Regardless, it didn't work for the case where nodes were defined in ascending order of slots.
Tetsuya's proposed patch didn't solve the problem for me, but it did correct the case where cpus/proc > 1. The final patch requires that we loop over the assignment
algo until all procs are assigned or all nodes are filled - any remaining procs are then handled in the cleanup loop.

- Move the ptrdiff_t tests up higher in configure.ac to be with the
rest of the type tests.
- Create new OMPI_FIND_MPI_AINT_COUNT_OFFSET for finding the
corresponding types of MPI_Aint, MPI_Count, and MPI_Offset.
Consolidate all the old C and Fortran tests into this new macro (and
.m4 file).
- Fix Fortran MPI_*_KIND tests that incorrectly keyed off assumed
types (e.g., int64_t) rather than whatever the corresponding C
MPI_Aint, MPI_Count, MPI_Offset types turned out to be.
- Add new logic to ensure that sizeof(MPI_Count) <= sizeof(size_t),
because our entire PML, BTL, and convertor infrastructure requires
this. As a side effect, just like MPI_Offset the same type of
MPI_Count (because MPI_Count has to be able to hold an MPI_Offset,
so we can't let MPI_Offset be larger than a MPI_Count).
