Luigi Rizzo e706181ba6 Major cleanup of the parser and printing routines in an attempt to
render the syntax less ambiguous.

Now rules can be in one of these two forms

	<action> <protocol> from <src> to <dst> [options]
	<action> MAC dst-mac src-mac mac-type [options]

however you can now specify MAC and IP header fields as options e.g.

	ipfw add allow all from any to any mac-type arp
	ipfw add allow all from any to any { dst-ip me or src-ip me }

which makes complex expressions a lot easier to write and parse.
The "all from any to any" part is there just for backward compatibility.

Manpage updated accordingly.
