Set the orte_bound_at_launch MCA variable. This resolves a launch
performance bug when using aprun to launch Open MPI processes. If
this variable is not set it can take minutes longer to launch with
high ppn.

Do not use opal_output_verbose inside O(n) loops. This was causing us
to make O(n) calls to snprintf which was greatly slowing launch at
scale.

This commit adds a new base enumerator type for variables that take of
the values -1, 0, and 1. These values are mapped to the strings auto,
false, true. This commit updates the mpi_leave_pinned MCA variable to
use the new enumerator.

* Since we are adding a new function to `mca_coll_base_module_2_1_0_t`
we need to increase the version of the module structure to `2_2_0`.
* Add a comment just above the PREDEFINED_COMMUNICATOR_PAD describing
it's purpose and when it should change. To help future developers
trying to answer the question noted in the comment.

* Similar to the other launchers (i.e., slurm, alps) we need to put the
children in a separate process group to prevent SIGINT (from a CTRL-C)
from being delivered to the whole process group and prematurely
killing the rsh/ssh connections to the remote daemons.

Fix the check for rsh/ssh so we allow the check for SGE and LoadLeveler to occur if user doesn't specify their own launch agent. Fix a Coverity warning

Check the exit status of major commands, as well as (optionally)
output the pwd and command being executed (when debugging). Also,
read the $debug variable from the environment; if it's set, go into
debugging mode (vs. requiring a modification to the script to enable
debugging mode).
Signed-off-by: Jeff Squyres <jsquyres@cisco.com>
If $debug is set in the environment, use that. This allows enabling
debug mode without requiring an edit to the script.

The filenames contain date/timestamps; if you compare those, the
tarball generated every night will *always* be new. Instead, separate
out the git hash from the old and new tarballs, and compare those.

- Add checks to the mpi/c interface `MPI_PARAM_CHECK`

It's possible that we can have zlib.h but still not have zlib support.
Use the correct macro to protect the usage of calling zlib functions.
This fixes 32-bit MTT builds at Cisco (e.g.,

Register namespace even if there is no node-local processes that
belongs to it. We need this for the MPI_Spawn case.

This commit fixes an error in teardown where the event bases are town
down before the peer structures are released. This causes us to call
event_del on an invalid event base. At best this makes valgrind
complain and at worst this causes aborts or segvs.
