Note update of hdf to version 4.1r5.

New Features and Changes:
========================

o The following Vdata routines were added:

     VSsetblocksize/vsfsetblsz -- sets the block size of the
                                  linked-block element.
     VSsetnumblocks/vsfsetnmbl -- sets the number of blocks for
                                  a linked-block element.
     VSgetblockinfo/vsfgetblinfo -- retrieves the block size and the number
                                    of blocks of a linked-block element.

o  Two routines were added to get compression information for the SD and
   GR interfaces, including chunked elements: SDgetcompress/sfgcompress
   and GRgetcompress/mggcompress.

   Note:

   - For a JPEG image, GRgetcompress only returns the compression type, not
     the compression information (i.e, quantity and force_baseline).  This
     information is not currently retrievable.

   - Getting compression type for JPEG chunked images is not working yet.

o  "hdp dumpgr" has a new option, -pd, to print palette data only.  Also,
   whenever option -p or -pd is given, only palettes are printed, and no
   images or file attributes.

o  A new FORTRAN function, heprntf (HEprint), was added.  It takes two
   arguments: file name and level.  If the file name string has 0 length,
   then error messages will be printed to standard output.

o  A memory leak in the netCDF portion of the HDF/mfhdf distribution
   was fixed.

o  The "#define NULL" was removed since ANSI C compilers are required to
   define NULL.

o  When using "hdp dumpgr", data was being printed in the range of 0-250
   when it should have been between 0-168.  This problem is now fixed.
