Update the calling interface to "sparse()".

Start off with

	sparse_initialize(argc, argv);

which will return the number of filenames found.  You can then use that,
or just check if *argv is NULL in a loop like

	while (*argv)
		list = sparse(argv);

where you get the declaration list for each file in turn.
