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.

One more commit for this ticket... as pointed out by Giles, we have
ompi_op_is_commute(). We should use that instead of replicating the
logic for the test.

Add some verbiage about how mpirun now defaults to disallowing running
as root, but you can use the --allow-run-as-root option to override
this default behavior.

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)...?

Clang 3.4 static analysis is now smart enough that it refuses to
compile our POSIX threading tests because we simply passed 0 for
several arguments (the test is checking for the linker presence of
symbols, so the NULL arguments didn't matter). Specifically, Clang's
anti-NULL compile-time checks now refuse to compile this bogus code.
Hence, these 2 configure test codes now have real variables and
pointers so that clang will compile it properly.
Without this fix, configure determines that there is no POSIX
threading support, and the osc/sm component fails to compile (which is
a different defect I'll be filing shortly). As such, we need this fix
in 1.8.1.
Also, change from the deprecated AC_TRY_LINK to AC_LINK_IFELSE.

The C99 usage to initialize via struct member names was already there,
but commented out. This commit doesn't fix any known problem; it
simply uncomments the C99 code, because it's safer/better.
This commit was SVN r31425.
Changed:
- Use ompi_mpi_group_null instead of MPI_GROUP_NULL.
- Asserts don't always quiet the clang static analyser. Change them to
ifs to really quite the warnings.

The algorithm was failing ibm/collective/allgather and iallgather. I
cleaned up the code to eliminate duplicate code paths and tracked the
issue down to an error in the way extra nodes in the knomial exchange
are handled. The new code is more compact and has been tested with up
to 64 ranks with the ibm test suite.

The file coll_ml_ibarrier.c wasn't included in coll/ml's Makefile.am
and the setup code from coll_ml_hier_algorithms_ibarrier.c was not
being called. It looks like this code is stale and has long since been
replaced by the code in coll_ml_barrier.c
Once all these little CMRs are approved I may make it into one roll-up
CMR to make it easier on the RM.

a segmentation fault in the reduce cleanup
Some of the changes address false warnings produced by scan-build. I
added asserts and changed some malloc calls to calloc to silence these
warnings.
The was one issue in cleanup for reduce since the component_functions
member is changed by the allreduce call. There may be other issues
with how this code works but releasing the allocated
component_functions after setting up the static functions addresses
the primary issue (SIGSEGV).

Many of the warnings were false warnings. These were silenced by
adding the appropriate asserts. Other warnings identified some
potential issues in error paths that should now be resolved.
