gcov.c (struct function_info): Make src an index, not a pointer.

	* gcov.c (struct function_info): Make src an index, not a pointer.
	(struct source_info): Remove index and next source fields.
	(fn_end): New static var.
	(sources_index): Remove.
	(sources): Now a pointer to an array, not a list.
	(n_sources, a_sources): New.
	(process_file): Adjust for changes to read_graph_file. Insert
	functions into source lists and check line numbers here.
	(generate_results): Only allocate lines for sources with
	contents.  Adjust for source array.
	(release_structures): Likewise.
	(find_source): Return source index, adjust for source array.
	(read_graph_file): Return function list.  Don't insert into source
	lists here.
	(read_count_file): Take list of functions.
	(solve_flow_graph): Reverse the arc lists here.
	(add_line_counts): Adjust for source array.
