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.
Thanks George, Nathan and Paul for the help.

* 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).

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.

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.
