* 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.
