This update should fix the mpirun man page so all
mpirun command line options are included, and
mpirun commands that have been removed are no
longer in the man page. I also fixed some of
the file formatting, and bolding of command
parameters.

Allow someone to specify the "pe=N" modifier to a mapping policy when N=1. This equates to just "bind-to core", but helps people who use a script to set the PE policy. Fix a bug where setting the binding policy left a lingering "if-supported" flag that shouldn't be there.

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.

add padding so the memory allocated by MPI_Win_allocate_shared()
is 64 bytes aligned.

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.

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).
