This PR renames the common library for OFI libfabric from
libfabric to ofi. There are a number of reasons this
is good to do:
1) its shorter and replaces 9 characters with three for
function names for what may eventually be a fairly extensive interface
2) OFI is the term used for MTL and RML components that use
the OFI libfabric interface
3) A planned OSC component will also use the OFI term.
4) Other HPC libraries that can use OFI libfabric tend to use
the term "ofi" internally and also in their configure options
relevant to OFI libfabric (i.e. MPICH/CH4, Intel MPI, Sandia SHMEM)
There seem to be comments in places in the Open MPI source
code that indicate that this common library will be going away.
Far from it as we will want to be able to share things like
AV objects between OMPI and possibly OSHMEM components that
use the OFI libfabric interface.
This PR also adds a synonym to the --with-libfabric(-libdir)
configury options: --with-ofi and with-ofi-libdir.

since Open MPI now requires a C99, and ptrdiff_t type is part of C99,
there is no more need for the abstract OPAL_PTRDIFF_TYPE type.

The ompi tree should be runtime independent, but over time a few
ORTE depedent definitions and functions have escaped into the ompi
tree. I'm working on my own runtime so I've used this as an opportunity
to get rid of ORTE dependencies in the ompi/ tree. I still need to go
back and change orte to conform to the new world and these changes are
untested, but I can now compile (but not link) without orte so I'm
commiting this changeset.

This commit fixes a bug that disabled both the RDMA pipeline and RDMA
protocols in ob1. ob1 was internally caching the values of
opal_leave_pinned and opal_leave_pinned_pipeline at init time. This is
no longer valid as opal_leave_pinned may be set by any call to a btl's
add_procs.

One should use the correct module object when calling
c_coll.coll_allgather. Otherwise there will be a segfault in the
case, for example, when hcoll is used. In that case
c_coll.coll_allgather = mca_coll_hcoll_allgather while
c_coll.coll_gather_module = tuned.

this fixes the issue reported by Nicolas Joly on the mailing: the sharedfp/lockedfile component does not support right now a scenario where multiple jobs read from the same input file, due to a collision of the filenames utilized for the sharedfp handle. Although not part of the oroginal report, the same occurs for the sharedfp/sm component. Add therefore the jobid to be part of the lockedfilename/sm file name.
use the OMPI_CAST_RTE_NAME macro to determine jobid

this commit brings over the behavior from the 2.x series to master, mostly with the fork for the 3.x series in mind.
Also, use strncasecmp instead of two strncmps

- 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.

Memory hooks are now set-up on demand. pml/yalla, mtl/mxm and
coll/hcoll need the memory hooks, so make sure those are installed.

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.

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`
