In preparation for moving the BTLs down to OPAL, discontinue the use
of the RML for connectivity client/agent communication. Instead, use
local unix domain sockets in the job session directory (all
communication is between processes on the same server, so unix domain
sockets are fine).

Update the Open MPI description and fix lots of grammatical errors in
the OpenSHMEM description.

Add the component use_udp value into the modex. If my component's
use_udp value doesn't agree with the use_udp value from a peer's modex
data, print a helpful message and disqualify the usnic BTL (the usnic
BTL will not be used). This prevents accidental customer
misconfigurations.

Trivial struct re-ordering to eliminate holes in the middle of the
struct (although there's still a hole at the end) and reduce the
overall size of the struct from 64 to 56 bytes. Also change mtu from
int to uint16_t; there was no need for it to be that large.

So track that the rte has reached that point, and only emit the new message if it is accurate.
Note that we still generate a TON of output for a minor error:

--------------------------------------------------------------------------
At least one pair of MPI processes are unable to reach each other for
MPI communications. This means that no Open MPI device has indicated
that it can be used to communicate between these processes. This is
an error; Open MPI requires that all MPI processes be able to reach
each other. This error can sometimes be the result of forgetting to
specify the "self" BTL.
Process 1 ([[50239,1],2]) is on host: Ralphs-iMac

MPI_INIT has failed because at least one MPI process is unreachable
from another. This *usually* means that an underlying communication
plugin -- such as a BTL or an MTL -- has either not loaded or not
allowed itself to be used. Your MPI job will now abort.
You may wish to try to narrow down the problem;
* Check the output of ompi_info to see which BTL/MTL plugins are
available.
* Run your application with MPI_THREAD_SINGLE.
* Set the MCA parameter btl_base_verbose to 100 (or mtl_base_verbose,
if using MTL-based communications) to see exactly which
communication plugins were considered and/or discarded.

top_ompi_srcdir -> OMPI_TOP_SRCDIR
top_ompi_builddir -> OMPI_TOP_BUILDDIR
We also split the srcdir/builddir flags according to their local tree (e.g., OPAL_TOP_SRCDIR), and tied them all together in configure.ac. Renamed ompi_ignore and ompi_unignore to be opal_<foo> as these are agnostic markers.
Only thing left is ompilibdir being treated similar to what we dif for srcdir/builddir. Coming soon.

We didn't AC_LANG_PUSH(C++) before checking to see if the compiler
supports -finline-functions, meaning that configure used the C
compiler for these checkes, not the C++ compiler.
Due to #2999, we have to fix both opal_setup_cxx.m4 and
ompi_setup_cxx.m4.
