Ralph Castain 4ef9d15d97 Revamp the opal mca paffinity interface. We ran into a problem when we encountered machines that had "holes" in their physical processor layout - e.g., machines that supported "hotplugging", or that had unpopulated sockets. To solve that problem, we had to clarify at the API level where we were describing physical vs logical processor info, and then translate accordingly in the underlying implementation.

See opal/mca/paffinity/paffinity.h for explanation as to the physical vs logical nature of the params used in the API.

Fixes trac:1435

Modify the configure system in the paffinity framework so that only one component is built. Cleanout variable name conflicts that on some systems prevented building

Makefile.am

Rename the osx paffinity component the "posix" component since it really has nothing osx specific in it - it is just a generic posix call to determine #processors. Set the priority low so that both linux and solaris components override it if they build. It shouldn't build in Windows at all.
