This commit implements onesided operations for noncontiguous
datatypes using two different algorithms.
* If the result and/or origin datatype is noncontiguous and the
target datatype is contiguous, then an iovec MD is created for
the result and origin. The operation is performed using a
single Portals4 call (unless it exceeds the max message size).
* If the target datatype is noncontigous, then an algorithm
similar to the one in osc-rdma is used to loop over the
contiguous blocks of each datatype. The operation is
performed using multiple Portals4 calls.
This commit ensures that individual operations do not exceed the
max atomic size or the max message size supported by the device.

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).

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.

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.,
