Clang 5.1 on my mac was a sad panda compiling a couple
of files, complaining about uninitialized stack variables.
This commit makes clang a happier panda (or at least not so sad).

Based on current implementation it is faster to use a blocking
send than the non-blocking version. Switch the exchange function
used in the barrier to use the blocking version combined with
the non-blocking version of the receive.
This is similar to open-mpi/ompi@223d75595d
* Print a verbose message if the component was disqualified because of
a negative priority.
* If a disqualified component provided a module, release it.
* Display list of selected components in priority order
- During the process of volunteering collective functions for a
communicator, print the component name and priority. This will
cause the verbose messages to be displayed in reverse priority
order (lowest priority first, up to highest). This is helpful
when determining which collective components are active in which
order for a given communicator.
To see the messages you need the following MCA parameter set to 9
or higher: `-mca coll_base_verbose 9`
* Adjust verbose for commonly needed verbose output from 10 to 9 to
make it easier to access this information.

Or at least that was the origin of the issue. It turns out
we were freeing the wrong buffer (but as it only happen in the
case of an error we never noticed).
This patch addresses most (if not all) @derbeyn concerns
expressed on #1015. I added checks for the requests allocation
in all functions, ompi_coll_base_free_reqs is called with the
right number of requests, I removed the unnecessary basic_module_comm_t
and use the base_module_comm_t instead, I remove all uses of the
COLL_BASE_BCAST_USE_BLOCKING define, and other minor fixes.
Fix CID 1325868 (#1 of 1): Dereference after null check (FORWARD_NULL):
Fix CID 1325869 (#1-2 of 2): Dereference after null check (FORWARD_NULL):
Here reqs can indeed be NULL. Added a check to
ompi_coll_base_free_reqs to prevent dereferencing NULL pointer.

some of the collective modules. Added a new function
opan_datatype_span, to compute the memory span of
count number of datatype, excluding the gaps in the
beginning and at the end. If a memory allocation is
made using the returned value, the gap (also returned)
should be removed from the allocated pointer.
in the base).
Correctly deal with persistent requests (they must be always freed when
they are stored in the request array associated with the communicator).
Always use MPI_STATUS_IGNORE for single request waiting functions.
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.
All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.

This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
