[svn-r6148] ./hdf5-devel/src/H5FDmpiposix.c

Purpose:
    Feature; Optimization

Description:
    Clients pass `-1' or make their own #define for HDF5 functions
    that take an optional object ID.

    Blue's GPFS is slow for typical SAF restart dumps.

Solution:
    Added a #define for H5I_INVALID_HID

    Added GPFS-specific code to H5FDmpiposix.c that tells mmfsd to
    forego byte range token prefetching. This code can be compiled
    into the library by defining USE_GPFS_HINTS. The plan is to either
    generalize this so it's detected during configure and turned
    on/off at runtime, or to move it up into DSL/SAF with the new HDF5
    functions to that return the low-level file handle.

Platforms tested:
    SuSE Linux (arborea), gcc and mpich-1.2.4
    SunOS (baldric), gcc
