Log Message:
Updated hdf5 to 1.4.0. 	For further details of changes see
${PREFIX}/share/doc/hdf5/RELEASE.txt.

New Features
============
   * The Virtual File Layer, VFL, was added to replace the old file
     drivers. It also provides an API for user defined file drivers.
   * New features added to snapshots. Use 'snapshot help' to see a
     complete list of features.
   * Improved configure to detect if MPIO routines are available when
     parallel mode is requested.
   * Added Thread-Safe support. Phase I implemented. See:

        http://hdf.ncsa.uiuc.edu/HDF5/papers/mthdf/MTHDFpaper.htm

     for more details.
   * Added data sieve buffering to raw data I/O path. This is enabled
     for all VFL drivers except the mpio & core drivers. Setting the
     sieve buffer size is controlled with the new API function,
     H5Pset_sieve_buf_size(), and retrieved with H5Pget_sieve_buf_size().
   * Added new Virtual File Driver, Stream VFD, to send/receive entire
     HDF5 files via socket connections.
   * As parts of VFL, HDF-GASS and HDF-SRB are also added to this
     release. To find out details, please read INSTALL_VFL file.
   * Increased maximum number of dimensions for a dataset (H5S_MAX_RANK)
     from 31 to 32 to align with HDF4 & netCDF.
   * Added 'query' function to VFL drivers.  Also added 'type' parameter to
     VFL 'read' & 'write' calls, so they are aware of the type of data
     being accessed in the file.  Updated the VFL document also.
   * A new h4toh5 utility, to convert HDF4 files to analogous HDF5 files.
   * Added a new array datatype to the datatypes which can be created.
     Removed "array fields" from compound datatypes (use an array datatype
     instead).
   * Parallel HDF5 works correctly with mpich-1.2.1 on Solaris, SGI, Linux.
   * You can now install the HDF5 documentation using the
     ``make install-doc'' command. The documentation is installed in the
     $(prefix)/doc directory where $(prefix) is the prefix specified by
     the (optional) ``--prefix'' flag during configuration.
   * HDF5 can operate correctly in the OpenMP environment in a limited way.
     Check doc/html/TechNotes/openmp-hdf5.html for details.
