Regarding BFO it should be mentionned that this component is currently
unmaintained, and that despite my efforts I could not make it compile
(it would not compile before this patch either).
This fixes a hang caused by the request refactor work. The cm pml was
not updated and was hanging is most cases.

The request.h header is unfortunately included files in the C++
bindings. C++ does not allow assigning from void * to another
pointer without a cast. This commit adds the cast. We can clean this
up when the C++ bindings are deleted.

It is verbotten to use opal_output() after the fork() but before the
exec()! It results in all manner of undefined behavior. For example,
on some OS X systems, if you run a trivial "hello world" MPI program
with a high level of ODLS verbosity:
```sh
$ mpirun -np 3 --mca odls_base_verbose 100 ./hello_c
```
You will see a bunch of output from the mpirun ODLS base, but then it
*may* hang in odls_default_module.c:do_child() -- after the fork() but
before the exec() -- while trying to opal_output() some debugging
statements.
The solution is to remove these extraneous opal_output() statements.
Indeed, the ODLS base is already outputting the same information that
these opal_output() statements are trying to emit, anyway.

* Remodel the request.
Added the wait sync primitive and integrate it into the PML and MTL
infrastructure. The multi-threaded requests are now significantly
less heavy and less noisy (only the threads associated with completed
requests are signaled).
* Fix the condition to release the request.
This commit adds support for the MPI-3.1 accumulate_ordering info
key. The default value is rar,war,raw,waw and is supported using an
MCA variable flag enumerator.

Add checks to bail out if our precomputed value is less
than needed (we are already at fault).

This commit changes the behavior of bml/r2 from conditionally
registering btl progress functions to always registering progress
functions. Any progress function beloning to a btl that is not yet in
use is registered as low-priority. As soon as a proc is added that
will make use of the btl is is re-registered normally.
This works around an issue with some btls. In order to progress a
first message from an unknown peer both ugni and openib need to have
their progress functions called. If either btl is not in use after the
first call to add_procs the callback was never happening. This commit
ensures the btl progress function is called at some point but the
number of progress callbacks is reduced from normal to ensure lower
overhead when a btl is not used. The current ratio is 1 low priority
progress callback for every 8 calls to opal_progress().

Take another shot at untangling the spaghetti
orterun: fix for command line parsing
orte-submit calls opal_init_util () before parsing out MCA command line
options (-mca, -am, etc). This prevents mpirun from setting opal MCA
variables for some frameworks as well as the MCA base. This is because
when a framework is opened all of its variables are set to read-only.
Eventually we want to lift this restriction on some MCA variables but
since -mca is affected we must parse out the MCA command line options
before opal_init_util(). This commit fixes the bug by adding a new
option to opal_cmd_line_parse (ignore unknown option) so orte-submit
can pre-parse the command line for MCA options.

Minor cleanups to avoid releasing/recreating the cmd line
As more providers get added to libfabric, the default exclude list would need
to be updated.
Instead, we choose to include only the providers known to work by default.
New default:
- include: psm,psm2,gni
- exclude: none
