This commit fixes a bug that can cause request and communicator leaks
when cleaning up an OSC window. The should prevent a hang seen with
IMB-EXT.

Due to a leak in the osc/rdma component we were running out of cids on
a one-sided tests. This resulted in a hang instead of an error. This
commit causes the nextcid algorithm to return an error if we run out
of cids.

feature
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.

Paul Hargrove pointed out that Stevens tells us that we should
FD_GETFL before FD_SETFL. And so we shall.
Make a new convenience function to do this (opal_fd_set_cloexec()),
just so that we don't have to litter this 2-step process throughout
the code.

Make sure that an internal, long-lived hwloc fd is marked as
close-on-exec so that children don't inherit it. This patch is
committed upstream in the hwloc master and v1.9 branches as 7489287
and b654e19, respectively. The patch applied here is the exact same
logic, but the surrounding code changed slightly since the hwloc v1.7
series, so the patch doesn't apply cleanly.

Make sure the debugger attach fifo is marked as close-on-exec so that
children procs don't inherit it. For example, if you salloc a SLURM
allocation and run "mpirun ..." in there (i.e., mpirun is running on
the head node, and launching on to back-end nodes), the forked srun's
will inherit this fd if it is still open.

Prior to r29058, this same logic was in place (i.e., ensure that the
extra fd to /dev/null is closed). It looks like it was accidentally
removed in the ORTE conversion to the state machine in r29058.
This ''might'' have something to do with many hangs that we're seeing
in Cisco MTT with jobs that exhibit failure (e.g., call MPI_ABORT)...?
