- Support MPI-2.2 and MPI-3.0 COLL features.
* `MPI_REDUCE_SCATTER_BLOCK`
* neighborhood collective communication
* nonblocking collective communication
- Add `*_BASE_ARGS` and `*_BASE_ARG_NAMES` for convenience.
- Use parameter names used in the MPI Standard.

This is mostly for error cases, where we need to release the
newly created proc. Currently the code deadlocks because the endpoint
lock is help at the release and the lock is not recursive.
Aslo added some code to print the IP addresses that don't match during
the TCP connection step.

Per a prior commit, the presence of "hwloc.h" can cause ambiguity when
using --with-hwloc=external (i.e., whether to include
opal/mca/hwloc/hwloc.h or whether to include the system-installed
hwloc.h).
This commit:
1. Renames opal/mca/hwloc/hwloc.h to hwloc-internal.h.
2. Adds opal/mca/hwloc/autogen.options to tell autogen.pl to expect to
find hwloc-internal.h (instead of hwloc.h) in opal/mca/hwloc.
3. s@opal/mca/hwloc/hwloc.h@opal/mca/hwloc/hwloc-internal.h@g in the
rest of the code base.

Frameworks are usually required to have a framework/framework.h file.
However, this is sometimes problematic (see the hwloc use case/problem
description, below).
This commit allows frameworks to have an "autogen.options" file (i.e.,
project/mca/framework/autogen.options) that specifies things that
autogen needs to know about the framework. Currently, the only option
recognized in autogen.options is "framework_header", which allows a
framework to specify that its header file is named something other
than "framework.h" (the framework header file must still be in the
project/mca/framework directory; it simply may be named something
other than framework.h). More options may be introduced over time.
The use case that motivated this is the hwloc framework
(https://github.com/open-mpi/ompi/issues/2616).
Per MCA framework rules, the hwloc framework is required to have an
opal/mca/hwloc/hwloc.h file. However, the hwloc library itself *also*
has an hwloc.h file. This causes a problem when configuring Open MPI
with --with-hwloc=external (meaning: do not use the hwloc embedded
within the Open MPI source code tree -- instead, use an hwloc
installation from outside the Open MPI source code tree).
Specifically, when in the opal/mca/hwloc directory, the presence of
"-I." in DEFAULT_INCLUDES (put there by Automake) causes a confusion
between the hwloc.h in opal/mca/hwloc/hwloc.h and the system-installed
hwloc.h. Chaos ensues (see the GitHub issue for more detail).
The solution is to rename the opal/mca/hwloc/hwloc.h to something else
(e.g., hwloc-internal.h), and extend autogen.pl to allow frameworks to
have an alternate name for their framework header file.
This commit introduces the autogen.pl mechanism to allow the alternate
header file name. A follow-on commit will effect this change in the
hwloc framework (and update all the places in the code base to use the
new filename).

This fixes a mismatch between PS listing that returned
USERNAME but code was pruning based on UID.
This changes the OPAL_PS_FLAVOR_CHECK format to return
'uid' instead of 'user'. (Note: Avoiding call to
getlogin_r() but assuming UID is uniform on system,
same assumption exists for session dir anyway.)
Note, still maintains behavior from man page for root
running orte-clean on node (kills all orteds).
Adds 'orte-dvm' to list of procnames that will be checked/killed.

As we changed the ABI (forcing a major release), we can limit
the size of the predefined communicators by moving the collective
structure outside the communicator. This might have a minimal,
but unnoticeable, impact on performance. This approach has been
discussed during the January 2017 devel meeting.

* Include a 'demo' component that shows some of the features.
* Currently has hooks for:
- MPI_Initialized
- top, bottom
- MPI_Init_thread
- top, bottom
- MPI_Finalized
- top, bottom
- MPI_Init
- top (pre-opal_init), top (post-opal_init), error, bottom
- MPI_Finalize
- top, bottom
* Other places in ompi can 'register' to hook into any one of these places
by passing back a component structure filled with function pointers.
* Add a `MCA_BASE_COMPONENT_FLAG_REQUIRED` flag to the MCA structure that
is checked by the `hook` framework. If a required, static component has
been excluded then the `hook` framework will fail to initialize.
- See note in `opal/mca/mca.h` as to why this is checked in the `hook`
framework and not in `opal/mca/base/mca_base_component_find.c`

Add ability to pass DVM URI purely via environment

export URI, mpirun w/o needing to add `--hnp` arg).
If user passes both envvar *and* cmdline, the cmdline wins.
