[svn-r633] Changes since 19980828

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

./RELEASE
	Updated with important changes I made since the second beta.

./src/H5A.c
./src/H5D.c
./src/H5Dprivate.h
./src/H5G.c
./src/H5Gprivate.h
./src/H5R.c
./src/H5Rprivate.h
./src/H5T.c
./src/H5Tprivate.h
	Any API function that used to take an `hid_t loc_id' followed
	by a `const char *name' can now take any type of object for
	the loc_id as long as the object is somehow associated with a
	file. Internally, H5G_loc() was modified to return an
	H5G_entry_t* instead of an H5G_t* so it's more general.

	Among other things, this allows one to retrieve information
	about an object like a named type or dataset without knowing
	the name of the type or dataset:

	    int
	    get_nlinks (hid_t obj)
	    {
	        H5G_stat_t	sb;
		if (H5Gstat(obj, ".", TRUE, &sb)<0) return -1;
		return sb.nlink;
	    }

./test/gheap.c
./test/istore.c
	These files needed a couple of changes because they call some
	of the internal functions whose H5G_t arguments changed to
	H5G_entry_t.

./src/H5A.c
	Got rid of all the switch statements for getting symbol table
	entries for varous objects and replaced them with a call to
	H5G_loc() allowing attributes to automatically apply to any
	type of object that belongs to a file.

./test/Makefile.in
	Moved the ragged array tests from the normal list of tests to
	the `make timings' target.

./test/ragged.c
	Added rewrite tests -- rewrite the rows of a dataset changing
	the number of rows and the length of each row.

./test/mtime.c
	Added a test that checks that H5Gstat() can be called with a
	dataset as the first argument.

./src/H5S.c
	Added #ifdef HAVE_PARALLEL around code to check for the
	HDF5_MPI_OPT_TYPES environment variable because the global
	variable that gets set is #ifdef'd.

./bin/release
	bzip2 uses .bz2 as the file extension.
