[svn-r129] Changes since 19970916

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

./config/depend.in
	Fixed backslashes in sed script because the H5Gnode.c
	dependency info was disappearing.  You'll have to rerun
	config.status to rebuild the Makefiles unless you use gnu
	make.

./config/conclude.in
	Also removes emacs backup files, TAGS, and svf backup files.

./config/linux
	Grouped gcc flags and added provisions for debugging vs. production.

./html/H5.format.html
	Updated messages 0x0008, 0x0009, and 0x000A.

./html/storage.html
	Documentation describing storage schemes.

./src/Makefile.in
./test/Makefile.in
	New source files.

./src/H5A.c
./src/H5Apublic.h
./src/H5C.c
	Changed VOIDP to void* in a couple places.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5B.c
./src/H5Bprivate.h
./src/H5G.c
./src/H5Gnode.c
./src/H5Gprivate.h
./src/H5H.c
./src/H5O.c
	Removed `const' from some variables because H5G_node_found() wanted
	to modify it's udata argument. Removing const there caused it
	to cascade to these other locations.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5B.c
./src/H5Gnode.c
./src/H5Gstab.c
./src/H5H.c
./src/H5O.c
	Added an extra argument to H5AC_find_f() and H5AC_protect(). This
	arg gets passed to the load() method.  Also added an extra
	argument to the H5AC_find() macro.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
	Extra argument passed to the sizeof_rkey() method.

./src/H5Fprivate.c
./src/H5Fistore.c (new)
	Added indexed I/O operations.

./src/H5G.c
./src/H5Gnode.c
./src/H5Gprivate.h
	Beginning to add H5G_open/close and related bug fixes.

./src/H5Oprivate.h
./src/H5Oistore.c (new)
	Added the H5O_ISTORE messsage (0x0008) for indexed storage of
	objects.

./src/H5private.h
	Added extra braces around both sides of the FUNC_ENTER() and
	FUNC_LEAVE() macros so FUNC_ENTER() can appear before
	declarations or after executable statements the second case is
	used by H5G_namei() to initialize output arguments to sane
	values before FUNC_ENTER() might return failure.

		int f ()
		{
		   int decl1;
		   printf ("This happens before FUNC_ENTER()\n");
		   FUNC_ENTER (...);
		   int another_declaration;

./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
	Extra arguments for key encoding and decoding.

./src/H5E.c
./src/H5Epublic.h
./src/H5Fistore.c
./src/H5Oistore.c
./src/H5Oprivate.h
	Indexed, chunked, sparse storage (not ready for general consumption
	yet).

./src/H5V.c		(new)
./src/H5Vprivate.h	(new)
./test/hyperslab.c	(new)
	Vector, array, and hyperslab functions.

./src/H5B.c
./src/H5Bprivate.h
./src/H5Fistore.c
./src/H5Gnode.c
./src/H5V.c
./src/H5Vprivate.h
./test/hyperslab.c
	Added functionality for indexed storage.

./src/H5F.c
	Fixed problems with seek optimizing.  Recommend we disable it
	until we can implement it in the file/address class since all
	of HDF5 must be aware of it.

./src/H5O.c
	Fixed comeent speling erorr :-)

./MANIFEST
	Added new files.

./config/conclude.in
	Added the word `Testing' to the test cases.  So if a test
	program is called hyperslab then the make output will contain
	the line `Testing hyperslab'.

./config/linux
	The default file I/O library is Posix section 2 on my linux
	machine so I can do some I/O performance testing.

./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
	Added ability to set size of indexed-storage B-tree.

./src/H5D.c
./src/H5E.c
./src/H5Epublic.h
./src/H5F.c
./src/H5Fprivate.h
./src/H5G.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gpublic.h
./src/H5Gshad.c
./src/H5Gstab.c
./test/stab.c
	Changed `directory' to `group' in numerous places.

./src/H5private.h
	The FILELIB constant can be set on the compile command-line.

./src/istore.c		     NEW
	Tests for indexed storage.
