Jeff Squyres fec7918eea Some paffinity functions had their return status overloaded:
* If < 0, it's an OPAL_ERR_* value
 * If >= 0, it's the actual output value of the function

This is problematic for the OPAL_SOS stuff.  This commit changes those
functions to always return OPAL_* statuses and send the output value
back through output parameters (like 95% of the rest of the code
base).  This avoids the confusion with OPAL_SOS stuff and makes
paffinity work again (e.g., mpirun --bind-to-core ...).

I updated all paffinitiy modules for the new function signatures, and
bumped the paffinity API version up to 2.0.1.  I don't think the
version change will matter, though, because we'll be introducing
support for hardware threads soon, which will either bump the
paffinity version again or we'll replace paffinity with 
a new framework.

This commit was SVN r23197.
