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
to simplify invocation from command-line (e.g., start dvm,
export URI, mpirun w/o needing to add `--hnp` arg).
If user passes both envvar *and* cmdline, the cmdline wins.
