Quincey Koziol 34b2fedf24 [svn-r8125] Purpose: ...

Bug fix/optimization

Description:
    Address slowdown in MPI-I/O file metadata operations that was introduced
mid-stream.  We now _require_ a POSIX compliant parallel file system for the
MPI-I/O file driver (as well as for the MPI-POSIX file driver).
    Also optimized file open operation when the file is being created by
reducing the number of collective & syncronizing calls.

Platforms tested:
    FreeBSD 4.9 (sleipnir) w/parallel
    h5committest
