"proto_tree_add_ipv4_format()" marks the field as being an IPv4 address,
so that, for example, the packet-filtering code knows that it should be
compared with an IP address, and you can say

	myproto.addr == www.sun.com

in a filter expression, rather than having to say

	myproto.addr == 192:18:97:241

(assuming we currently support comparisons on "sequence of bytes"
fields).
