We extend gpfs filesystem to PE.  Right now, the main accomodation is
for ROMIO aggregation selection using MP_IOTASKLIST to mimic current PE
functionality

reconfiguration changes from bg to gpfs with platformspec; removal of
lockless

The only reason these locks exist is becuse way back in BGL days someone
at IBM thought it might be a good idea to have one driver that could
access both NFS and GPFS.  There was also some concern about a large
write call getting split up by the i/o forwarder.  fortunately, MPI-IO
semantics mean applications that would be harmed by such a split already
face "undefined" behavior.
