process id in DA

[Shao-Ching Huang]

On the first and last processes along each partitioned direction, I
have some extra operations to do. Currently I test the global indices
(using DAGetCorners) to achieve a similar effect, but was wondering if
there is already some one-shot function call available.

Thanks,

Shao-Ching
