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.

* Complete rewrite of opal_pointer_array
Instead of a cache oblivious linear search use a bits array
to speed up the management of the free space. As a result we
slightly increase the memory used by the structure, but we get a
significant boost in performance.

* Do not register datatypes in the f2c translation table.
The registration is now done up into the Fortran layer, by
forcing a call to MPI_Type_c2f.

With this, libs (e.g., "-ldl") are not added to the wrapper LIBS
flags. This may work on some platforms, but on at least RHEL 7.3, it
does not (i.e., compiling MPI applications fails because it can't find
dlopen).

* `ompi_info --show-failed` will include the failed components along
with information about why they failed.

* Add a path for failed component load information to be reported up.
* This allows ompi_info to display this information inline to make it
easier for folks to see if the component is present but failed for
some reason. Most likely a missing library, but could be a libnl
conflict.
* Add MCA parameter to enable this feature:
- `mca_base_component_track_load_errors` takes a boolean
- Default: `false`

So that we can stop asking common questions like "What version of Open
MPI are you using?", etc.

The fact that application proc called Abort (read failed) doesn't
mean that ORTE subsystem has failed - vice versa it does it's work
to gracefuly exit the whole application.
orted exiting with non-zero status creates a problem for at least
plm/slurm environments where orteds are launched via `srun` with
"--kill-on-bad-exit" flag. If one of orteds has exited with non-
zero status slurm will immediately kill all other orteds. As the
result we see a lot of leftover in the `/tmp` directory.

Array sizes of `array_of_gsizes`, `array_of_distribs`, `array_of_dargs`,
and `array_of_psizes` parameters of the `ompi_datatype_create_darray`
function (and `MPI_TYPE_CREATE_DARRAY`) are all `ndims`.
`ndims` are `i[2]`, not `i[0]`. See MPI-3.1 p.122.
Because this function `__ompi_datatype_create_from_args` is used by
pt2pt OSC, using a datatype created by `MPI_TYPE_CREATE_DARRAY` for
`MPI_(R)(GET_)ACCUMULATE` caused a segmentation fault or something
on a target process.
