PVFS v2 patches for ROMIO

MPICH2 releases since the MPICH2-0.971 (released on 9 September 2004) have contained a PVFS v2 driver for ROMIO. Backporting the latest changes to older MPICH2 releases is fairly challenging. Users of PVFS v2 and ROMIO are encouraged to upgrade to the latest versions of MPICH2.
