[svn-r735] Changes since 19981002
----------------------

./src/H5D.c
	Fill values are working for contiguous datasets now except
	there are two things that need more support from the data
	space layer, specifically the ability to form a selection from
	the difference of two selections.  They are (1) extending an
	external contiguous dataset, (2) optimization by delaying the
	fill until after the first H5Dwrite().

	Renamed H5D_allocate() to H5D_init_storage() since allocation
	is only part of the story. Added a data space argument so it
	doesn't have to query the space from the object header -- the
	space is always available in the caller anyway.

	Removed `#ifdef HAVE_PARALLEL' from a few places where it
	wasn't necessary.  We don't need it around code that doesn't
	compile anything from mpi.h or mpio.h.

./src/H5Fistore.c
	Uncommented H5F_istore_alloc() for non-parallel and moved the
	`#ifdef HAVE_PARALLEL' just around Kim's barrier.

./src/H5Fmpio.c
	Wrapped a couple long lines.

	Got rid of two signed vs. unsigned comparison warnings.

./MANIFEST
./test/Makefile.in
./test/fillval.c	[NEW]
	Added tests for fill values.  The contiguous dataset extend
	test is disabled until H5S_SELECT_DIFF is implemented.

./tools/Makefile.in
	Fixed a bug where `make test' didn't build the executables
	first. This should cause the snapshots to start up again.

./Makefile.in
	Changed to build in `test' directory before `tools'
	directory. We want the library tests to pass before we even
	start considering the tools.  You can still build and/or test
	the tools independent of the library tests passing.
