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).
This commit was SVN r31710.
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.

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.

In abusive MPI communication patterns, sending a UDP ping only once a
second may not be sufficient -- all the UDP pings may be dropped. So
increase the frequency of the pings to every quarter second, and allow
more total pings to be sent.
Total timeout time is still the same (10 seconds) -- we'll just now
try 40 times (i.e., once every quarter second) as opposed to 10 times
(i.e., once a second). Testing has shown that this frequency allows
the connectivity checker to always succeed even in the many-to-one
abusive communication patterns.

We're passing a char foo[x] into PACK_BYTES, so we don't need to take
its address in the macro. This is parallel to the UNPACK_BYTES macro
(where we pass a char bar[x] into it, and don't take its address in
the macro).
The value we're packing is only used to output in a show_help message,
which is why this wasn't noticed before (i.e., it's not used in
network or addressing that would have caused a failure).

There's a requirement in several places (e.g., opal dstore) that
sizeof(ompi_process_name_t) -- which comes from the compile-time
selected ompi/mca/rte component -- is equal to sizeof(uint64_t). If
it's not, Bad Things will happen.
So put an assert here to catch that case.

The old default context id maximum was committed to the trunk in

This commit should fix a hang seen when running some of the one-sided
tests. The downside of this fix is it reduces the maximum size of the
messages that use the fast boxes. I will fix this in a later commit.
To improve performance under a heavy load I introduced sequencing to
ensure messages are given to the pml in order. I have seen little-no
impact on the message rate or latency with this change and there is a
clear improvement to the heavy message rate case.
Lets let this sit in the trunk for a couple of days to ensure that
everything is working correctly.

The was one issue in cleanup for reduce since the component_functions

with how this code works but releasing the allocated

the primary issue (SIGSEGV).
