[svn-r329] Changes since 19980324

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

./src/H5D.c
	Zero element requests for H5Dread() and H5Dwrite() succeed.

./src/H5F.c
./src/H5Fprivate.h
	All files will have a root group. This greatly simplifies the
	library at the expense of ~1k extra bytes in files that have
	only one object.

./src/H5D.c
./src/H5Dprivate.h
./html/Groups.html
	Functions that used to take a file ID and an object name can
	now take a group ID instead of a file ID.  This doesn't change
	the API, only it's documentation.

./src/H5G.c
./src/H5Gprivate.h
./src/H5O.c
./src/H5Oprivate.h
	Removed extra file arguments from some internal functions
	since the file pointer can be found from the group pointer or
	a symbol table entry (ent->file or H5G_fileof(group)).
	Besides, when we eventually implement mounting one file on
	another, H5G_namei() might return a different file than what
	you gave it, and that file is part of the returned symbol
	table entry.

./src/H5G.c
	Fixed bug with `.' appearing in a name. It used to hang the
	library.

./src/Makefile.in
./src/h5ls.c		[NEW]
./MANIFEST
	Added `h5ls' a simple program that takes a file name and a
	directory and lists the contents of that directory using
	H5Giterate().

./test/istore.c
	Changed an argument to H5G_create().

./test/tstab.c
	Removed test_1 which was testing that files with a single
	object don't have a root group.  This no longer applies.
