Previously, the connectivity agent was pretty dumb: it took whatever
pings it got and ACKed them. Then we added an agent check to ensured
that the ping actually came from the source interface that it said it
came from. Now we add another check such that when a ping is received
on interface X that corresponds to usnic module Y, we ensure that the
source interface of the ping is on the all_endpoints list for module Y
(i.e., module Y expects to be able to talk to that peer interface).
This detects cases where peers have come to different conclusions
about which interfaces should be used to communicate (which is bad!).
This usually reflects a network misconfiguration.

r32354 breaks gfortran if you --enable-mpi-fortran, because it assumes
the value "all", when then errors out of configure because gfortran
can't currently build the mpi_f08 bindings.
Need to think about what the Right solution is here...

Ensure that incoming "ping" messages came from the IP address that
they think they came from. If they don't, drop them (because it is
probably routing error), which will likely eventually cause the
connectivity checker to timeout, and therefore cause the job to abort.

Update compat.h to only handle compatability between v1.7/v1.8 and
v1.9/2.0 (i.e., the current trunk). Remove what seems to be the last
vestiages of OMPI/ORTE pollution in the now-OPAL-ized usnic BTL.
Currently use a hard-coded constant for the MCW size (i.e.,
MPI_COMM_WORLD size) for some initialization values in the v1.9/2.0
series; still need to figure out something better there.

Adapt to moving down to OPAL: find a PML-registered error callback,
and use that when we don't have a module context and we need to abort.
Failing that, just call exit().

communication library should use to initialize itself.
Ralph will champion this change back with an RFC if there is a realistic
need/use case from the community.

If --with-usnic is specified and we can't build the usnic BTL, abort.
If --without-usnic is specified, gracefully skip building the usnic
BTL. If neither is specified, do the OMPI-default behavior: try to
configure/build the usnic BTL, and if we can't, skip it.

The only user of this code was coll/sm. I implemented a basic replacement
for the removed code. This gets the trunk compiling again with
--disable-dlopen.

common/ofacm is only used by the iboffload code in ompi. This code does
not currently work so it is safe to ignore these components until it is
fixed.
