[svn-r620] Changes since 19980825

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

./MANIFEST
./src/H5R.c		[NEW]
./src/H5Rprivate.h	[NEW]
./src/H5Rpublic.h	[NEW]
./src/Makefile.in
./src/hdf5.h
./test/ragged.c		[NEW]
	Preliminary support for 2d ragged arrays for Mark Miller and
	Jim Reus.  Not fully implemented yet. The test is not actually
	part of `make test' because we still have some memory problems.

./src/H5E.c
./src/H5Epublic.h
	Added H5E_RAGGED as a major error number.

./bin/release
	Checks the MANIFEST file against `svf ls' on systems that have
	it.

./bin/trace
	Fixed a bug that caused arguments of type `void *x[]' to not
	be handled.

./src/H5.c
	Removed unused variables and changed a couple types to
	fix compiler warnings.

	Added tracing support for ragged array object ID's and arrays
	of pointers.

./src/H5D.c
	H5Dcreate() will complain if either of the property lists are
	invalid (instead of using the default).

./src/H5D.c
./src/H5Dprivate.h
	Split H5Dget_space() into an API and internal function so it
	can be called from the new ragged array layer.

./src/H5Fistore.c
	Fixed warnings about unsigned vs. signed comparisons.

./src/H5Flow.c
	Fixed a warning about a variable being shadowed in the MPI-IO
	stuff.

./src/H5Iprivate.h
./src/H5Ipublic.h
	Added the H5_RAGGED atom group.

./src/H5Shyper.c
	Fixed some freeing-free-memory errors that resulted when
	certain arrays were freed but the pointers were left in the
	data structures.  I simply set the pointers to null after they
	were freed.

./src/H5Sprivate.h
./src/H5Sselect.c
	Split the H5Sselect_hyperslab() function into an API and a
	private function so it could be called from the ragged array
	layer.

	Added H5S_SEL_ERROR and H5S_SEL_N to the switch statements to
	get rid or compiler warnings.

./src/H5Tconv.c
	Removed a misleading comment.

./test/bittests.c
	Fixed a warning about a printf().

./test/cmpd_dset.c
	Fixed warnings about unused variables because of test #11
	being commented out.

./bin/trace
	Shortened the right margin for the output to allow room for
	the `);' at the end of the TRACE() macros.
