WHAT: Remove all non-hwloc paffinity components.

WHY: The hwloc component supports all those systems.

WHERE: opal/mca/paffinity/[^hwloc|base] directories

WHEN: for 1.5.1

TIMEOUT: Tuesday call, May 25 (yes, about 2 weeks from now -- let hwloc soak 
for a while...)

-----------------------------------------------------------------------------

MORE DETAILS:

As you probably noticed, I have (finally) committed the "hwloc" paffinity 
component to the trunk and removed the "linux" (i.e., PLPA) paffinity component:

    https://svn.open-mpi.org/trac/ompi/changeset/23125
    https://svn.open-mpi.org/trac/ompi/changeset/23126

hwloc supports all systems that OMPI supports (and several that OMPI doesn't!) 
-- more specifically, it supports all the other systems that we have paffinity 
components for (darwin, linux, posix, solaris, windows).  It can therefore 
fully replace all the other paffinity components.

Indeed, the new hwloc's default priority is higher than all of the other 
current paffinity components, so over the next week or two, it'll be a good 
soak test to see if it is working properly.  Once we get any kinks worked out, 
I propose removing all the other paffinity components and leaving only hwloc.

That being said, we might as well leave the paffinity framework around, even if 
it only has one component left, simply on the argument that someday Open MPI 
may support a platform that hwloc does not.
