[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
