Fix a problem in packing/unpacking job updates. There remains a race condition that causes messages to attempt to be sent to the second new daemon before it is completely ready. Not entirely sure where it is coming from.

Rebase to master. Reset orte_nidmap_communicated if hosts are added. Check for duplicate hostnames in an add_host command. Turn off tree_spawn for dynamic launch of additional daemons.

Search for the digits to be compressed from the end of the node names.
For example, if the nodelist is c712f6n01,c712f6n02,c712f6n03
the regx/fwd component generates c[3:712]f6n01,c[3:712]f6n02,c[3:712]f6n03@(3)
when the regx/reverse component generates c712f6n[2:1-3]@0(3) which is
a better fit here.

among other things, that will make testing way easier.

Resolve a race condition between registering for a file to be removed upon termination and actual creation of that file by providing attributes that identify whether the path is a file or directory. This removes the need for PMIx to detect the difference.

Handle the need for different regex generator/parsers by moving the
orte/util/nidmap and orte/util/regex code into a new "regx" framework.
Use the original code to complete a "fwd" component, and create a
scaffold for IBM's "reverse" component.

Per MPI 3.1 chapter 13.3 :
"Derived etypes can be constructed by using any of the MPI
datatype constructor routines, provided all resulting typemap
displacements are non-negative and monotonically nondecreasing."
Same restriction applies to ftypes.
add the OMPI_DATATYPE_CHECK_FOR_VIEW() macro that is
check the underlying opal_datatype_t is monotonic, on top
of all checks performed in OMPI_DATATYPE_CHECK_FOR_RECV().
Since checking monotoniciy is expensive, check is only performed
when needed, but the result is cached by ompi_datatype_is_monotonic().
Thanks Wei-keng Liao for the valuable feedback.
Thanks George for the guidance.

Now that the daemon calls remote_spawn itself, there is no longer
a need for the "tree_spawn" command nor the associated command
processing code since the HNP is no longer sending a tree-spawn
message to the orted.

This parameter can be used to set the node regex max length that can
be passed to the orted command line.
For testing purpose, it can be set to zero in order to force the node regex
being retrieved by orted from its parent.
