Squelch various signed vs. unsigned warnings by:

	making pointers to byte data be "guint8 *" rather than "char *",
	and making buffers holding byte data arrays of "guint8" rather
	than arrays of "char";

	making pointers to text strings "char *" rather than "guchar *";

	appropriately casting pointers (cast to "guint8 *" when passing
	to routines expecting "guint8 *" or when assigning to "guint8
	*");

	making port-number preferences "guint";

	making enum preferences "gint";

	making hf_ variables "int".

Clean up white space.
