b68d66bb9b MCA: Add the project/project version to the MCA base component
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.

b57b8c5b3f Clean up request handling in the I/O framework to be more consistent with
other request-using frameworks.

 - Rather than having mpi/c/* functions allocate requests explicitly,
   pass the MPI_Request* down to the I/O component and have it 
   perform the allocation.
 - While the I/O base provides a base request which can be used,
   it is not required and all request management occurs within
   the component.
 - Push progress management into the component, rather than having it
   happen in the base.  Progress functions are now easily registered,
   and not all (ie, the one existing) components use progress functions
   in any rational way.

ROMIO switched to generalized requests instead of MPIO_Requests many
moons ago, and Open MPI now uses ROMIO's generalized requests, so there
is no reason to wrap those requests (which are OMPI requests) in another
level of request.

Now the file function passes the MPI_Request* to the ROMIO component,
which passes it to the underlying ROMIO function, which calls 
MPI_Grequest_start to create an OMPI request, which is what gets set
as the request to the user.  Much cleaner.

This patch has two motivations.  One, a whole heck of a lot of code
just got removed, and request handling is now much cleaner for I/O
components.  Two, by adding support for Argonne's proposed generalized
request extensions, we can allow ROMIO to provide async I/O through
generalized requests, which we couldn't rationally do in the old
setup due to the crazy request completion rules.

0af7ac53f2 Fixes trac:1392, #1400
* add "register" function to mca_base_component_t
   * converted coll:basic and paffinity:linux and paffinity:solaris to
     use this function
   * we'll convert the rest over time (I'll file a ticket once all
     this is committed)
 * add 32 bytes of "reserved" space to the end of mca_base_component_t
   and mca_base_component_data_2_0_0_t to make future upgrades
   [slightly] easier
   * new mca_base_component_t size: 196 bytes
   * new mca_base_component_data_2_0_0_t size: 36 bytes
 * MCA base version bumped to v2.0
   * '''We now refuse to load components that are not MCA v2.0.x'''
 * all MCA frameworks versions bumped to v2.0
 * be a little more explicit about version numbers in the MCA base
   * add big comment in mca.h about versioning philosophy

612570134f The request management framework has been redesigned. The main idea is
to let the PML (or io, more generally the low level request manager)
to have it's own release function (what was before the req_fini). This
function will only be called from the low level while the req_free will
be called from the upper level (MPI layer) in order to mark the request
as not used by the user anymore.

From the request point of view the requests will be marked as inactive
everytime we read their status (true for persistent as well). As 
MPI_REQUEST_NULL is already marked as inactive, the test and wait functions
are simpler. The drawback is that now we have to change in the
ompi_request_{test|wait} the req_status of the request once we get it's
status.

a46d0d3801 Add support to Open MPI for MPI_Register_datarep, as ROMIO now has support for the
functionality.  This is a global registration, so all components have to be made
aware of the registration -- therefore, do things at the component level, not the
module level.
