if some other code need them, then it should include this file
instead of having it's own redefinition of these externals.

Back out r14073 - it speeds up TCP latency / bandwidth but at the same time
it kills ROMIO and one-sided performance when using only TCP. The problem
is that it only allows those two to be progressed every couple of seconds,
leading to what looks like hangs in the one-sided tests (and the ROMIO stuff,
although people seem to not notice that at this point).

OPAL_FREE_LIST_WAIT/RETURN will not use locks in a non-threaded build
conditionaly use locks if non-threaded around the OPAL_FREE_LIST_WAIT/RETURN
seems to fix the issue
Tested at 4K processes and seems to work..

any listen mode, which is what we were doing before :/

it limits the number of circular buffers allocated between each pair of peers.
This allows for more tight memory usage control.

development trees since last year (had to wait for some intel tests to
run yesterday, so I finally took the time to finish this work):
* Improve MPI API argument checking by also checking for NULL values
(especially helps when invalid Fortran MPI handles are passed,
because the various MPI_*f2c functions are supposed to return an
"invalid" MPI handle [meaning NULL] when this happens). So now
OMPI will generate an MPI exception rather than a segv.
* Removed a few redundant DATATYPE_NULL checks.
* Also check for some other forms of "invalid" handles (e.g., already
been freed, etc.) in some cases. We could probably be a bit more
stringent in this regard if we really wanted to.
* Change MPI_Get_processor_name to zero out the string up to
MPI_MAX_PROCESSOR_NAME characters, because the MPI spec says that
the string must be at least that long. We were already passing
that length to gethostname(), anyway.

latency is high and the network relatively fast. This will allow for more kernel
level buffering, which allow overlap between system calls and communications.
Somehow, even on fast clusters there is an improvement (non significant).
This patch create multiple modules for the same device, which in turn will
create multiple sockets between the peers. By default the number of BTL by
device is set to 1, so there is no fundamental difference with the current
version. Change the value of btl_tcp_links to enable multiple links between
peers.

when we precalculate most of the addresses there is no point to have separate
BTL for this. The sm_progress() code become much more simple as a result.

- Add signal handler BLCR register (helps with debugging)
- ifdef out the cr_request_file section for checkpointing self.
There is a bug with the 0.4.2 version of BLCR such that this
does not handle moving checkpoint files around.
I'm following up with the BLCR folks on this one (and checking
the newest release).
