The usNIC BTL does not use more than 1 iov, so be sure to set it to 1
so that we don't allocate cq/rq/sq entries based on a default (i.e.,
>1) number of iovs per entry.

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.

This commit recategorizes several mpirun arguments,
and moves the information for mpirun --help arguments
to the bottom of the general help message. I also
added the OPAL_CMD_LINE_OTYPE field to two commands
that were missed initially because they were not
in the same area as the others.

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

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).

Adds:
- enabling/disabling of timings throught environment variable `OMPI_TIMING_ENABLE`
- output format: [file name]:[function name]:[description]: avg/min/max
- dynamically extending array of results for case then inited size was exhausted
- catch and collect errors
- cleanup
Note:
For use feature need to configure with `--enable-timings`
and set env `OMPI_TIMING_ENABLE = 1`

This commit adds new timing feature that uses environment variables to
expose timing information. This allows easy access to this data (if
timing is enabled) from any other part of the application for the subsequent
postprocessing.
In particular this will be integrated with OMPI-level timing framework that
whill use MPI_Reduce functionality to provide more compact and easy-to use
information.
This commit also adds the example of usage of this framework by annotating
rte_init function. The result is not used anywhere for now. It will be
postprocessed in subsequent commits.
NOTE: that functionality is currently disabled untill it will be verified at runtime

This commit adds a "parsable" option to the help
arguments, which prints out a machine readable
list of all the mpirun options.
Fixes#3279
Signed-off-by: Nathaniel Graham <ngraham@lanl.gov>
This commit modifies the output from the mpirun --help
command. The options have been split into groups, to
make the output smaller and more readable. The groups
are: general, debug, output, input, mapping, ranking,
binding, devel, compatibility, launch, dvm, and
unsupported. There is also a special "full" command
that can be used to get the old behaviour of printing
out all of the options. Unsupported options may only
be seen with this full output.
This commit also adds a special case for the help
argument. It makes it possible for the user to
enter 0 or 1 arguments instead of having to always
enter an argument. This defaults to printing out
the "general" help options so the user can then
see what help arguments there are.

Several component-specific functions were named with a prefix of
"opal_timer_base", which was quite confusing. Rename them to have a
prefix "opal_timer_linux" to make it clear that they are here in this
component (and different than *actual* opal_timer_base symbols).
