[svn-r353] Changes since 19980414

----------------------

./html/Compression.html          [NEW]
./html/Datasets.html
./html/H5.format.html
./html/H5.user.html
        Documented compression.  A couple of the H5P functions aren't
        quite implemented yet but they're coming soon...

./src/H5Dprivate.h
./src/H5E.c
./src/H5Epublic.h
./src/H5Farray.c
./src/H5Fistore.c
./src/H5Fprivate.h
./src/H5MF.c
./src/H5MFprivate.h
./src/H5O.c
./src/H5Ocomp.c         [NEW]
./src/H5Oprivate.h
./src/H5P.c
./src/H5Ppublic.h
./src/H5Sprivate.h
./src/H5Ssimp.c
./src/H5Z.c             [NEW]
./src/H5Zprivate.h      [NEW]
./src/H5Zpublic.h       [NEW]
./src/Makefile.in
./src/hdf5.h
./test/dsets.c
./test/istore.c
        Compression is now mostly working.  Don't try to open a
        compressed dataset though because the compression message
        won't be read.

./html/Datatypes.html
./html/H5.api.html
./src/H5.c
./src/H5private.h
./src/H5D.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
        Added timing support.  When compiled with H5T_DEBUG defined
        the library will print conversion bandwidths when the library
        closes.  The H5Tregister functions take a string as the first
        argument so the statistics output is meaningful.

./MANIFEST
        Added new files.

./configure.in
./src/H5config.h.in
        Check for getrusage().  Check for compress2() in libz.a and
        the zlib.h header file.  Added `z' to the debug list.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
./src/debug.c
        Cleaned up some indentation and added support to print istore
        B-trees.  From the debugger, give the B-tree address and the
        dimensionality from the layout message of the object header.

./src/h5ls.c
        The oid is printed as  w:x:y:z where w and x are the file ID
        and y and z are the OID within the file.  You can give z or
        y*2^32+z as an argument to the debugger to print the object
        header for the object.

./src/H5AC.c
        Cleaned up statistics and made them match those reported by
        H5T and H5Z.

./src/H5MM.c
./src/H5MMprivate.h
./src/H5Fistore.c
        Finally got rid of a couple of long-standing const cast
        warnings.

+ * A compression function takes some configuration data which comes from the
+ * compression message, namely FLAGS, CD_SIZE, and CLIENT_DATA.  It should
+ * read SRC_NBYTES from SRC and compress them into at most DST_NBYTES of DST.
+ * If the compressed data would be larger than DST_NBYTES the function should
+ * return a value greater than or equal to DST_NBYTES.  On failure the
+ * function may return zero.
+ *
+ * The uncompression function is the inverse of compression and takes the
+ * same arguments.  The SRC_NBYTES argument is the number of compressed bytes
+ * in SRC.  The function should uncompress SRC into DST. For redundancy,
+ * DST_NBYTES contains the size of the DST buffer although if the algorithm
+ * is operating properly and the file has not been corrupted the uncompressed
+ * data will never be larger than DST_NBYTES.  The function should return the
+ * number of bytes in the DST buffer or zero on failure.  Failure includes
+ * the overflow of the DST buffer.
