[svn-r5799] Purpose:
New feature. Description: Added MPI-posix VFL driver. This driver uses MPI to coordinate actions, but performs I/O directly with posix sec(2) I/O functions. This driver should _NOT_ be used if the file accessed is not on a parallel filesystem. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
