Add routines to file.c to indicate whether:

	a save can be done ("can" in the sense of "there's something to
	save" and in the sense of "we can write that something out");

	a "save as" can be done (in the sense of "we can write what we
	have out");

	there's unsaved data to save (which might be unsaved changes or
	might be a temporary file full of packets);

and use them as appropriate.  This means that the "unsaved data"
indicator in the UI will be turned on for temporary files full of
packets as well as for files with unsaved changes; that's what we want.
