This commit adds a check to see if the target is in an access epoch. If
not we return OMPI_ERR_RMA_SYNC. This fixes test_start3 in the onesided
test suite. The cost of this extra check is 1 byte/peer for the boolean
flag indicating that the peer is in an access epoch.
I also fixed a problem where mupliple unexpected post messages are not
correctly handled.

If the btl_usnic_connectivity_map MCA param is set to a non-NULL
value, then each MPI process will output a file named
<prefix>-<hostname>.pid<pid>.job<jobid>.mcwrank<MCW rank>.txt. Its
contents will detail which usNIC device(s) (and therefore which
link(s)) are being used to communicate with each peer MPI process.
Here is a sample output file (named
mpi005.pid26071.job1640759297.mcwrank0.txt):

This corner case is now handled in the pml so the same code
is invoked for both MPI_Start and MPI_Startall.
This also correctly report an error if MPI_Startall is invoked twice
on a MPI_PROC_NULL persistent request.

ibv_create_ah() can also return EHOSTUNREACH, which means that there

RHEL 7 has shipped with kernel support for the RDMA_TRANSPORT_USNIC
enum, but ''not'' the RDMA_TRANSPORT_USNIC_UDP enum. This means that
when you install usNIC drivers from cisco.com, the kernel will report
IBV_TRANSPORT_USNIC, even though the transport is actually using UDP.
Therefore, we have to modify the logic in common/verbs to do the
additional magic probe if the device reports either an
IBV_TRANSPORT_IWARP or IBV_TRANSPORT_USNIC (because both of those might
be lies -- do the probe to figure out the real transport).
The code changed by this patch is fairly trivial; it simply moves the
logic of the magic probe to its own short function, and then calls that
short function in both the IBV_TRANSPORT_(IWARP|USNIC) cases. It looks
longer because several lengthy comments were also updated.

Based on extensive discussions before/at the June 2014 developer's
meeting, put a lengthy comment explaining a second reason why we
''must'' use an RTE barrier during MPI_FINALIZE and
MPI_COMM_DISCONNECT (i.e., unreliable transports). Slightly explain
more the original reason why we do this, too (BTLs can lie/buffer a
message without actually injecting it on the network).

rtnetlink doesn't check the source address when determining whether to
return route info for a query. So we need to check that the OIF matches
the OIF of the source interface name. Without this check, OMPI might
pair a local interface which does not have a route to a particular
remote interface.

At the developer meeting today, the question was raised as to whether
the SCTP BTL was maintained any more. I emailed Alan Wagner to see if
he had any interest/resources to continue to maintain the SCTP BTL.
He indicated that he unfortunately had any resources to maintain it;
it would be fine to remove the SCTP BTL from the trunk.
So long, SCTP BTL... fare thee well...

1: find/create procs, and create associated endpoint for each

The 2nd part is done as a separate loop so that the address lookups
can be parallelized.
The overall result is to split usnic_add_procs() into two smaller,
simpler parts.

When ibv_create_ah() fails due to an address resolution failure, it
really only means that we can't reach that one peer -- so we should
just ignore that one peer. If ibv_create_ah() fails for some other
reason, then give up on the entire usnic_X device.
Change the show_help() message that is displayed when ibv_create_ah()
fails due to address resolution failure; indicate that it's likely a
routing problem. Also opal_output_verbose() the same info, since
show_help() is de-duplicated (and this particular show_help() message
can be squelched).
