Log message:
introduce route labels, allowing for up to 32 bytes of info to be attached
to a route.
the label is sent over the routing socket wrapped into a new
struct sockaddr_rtlabel, allowing for handling it like any other sockaddr.
struct rtentry only contains a (16 bit) label-ID, with the actual labels
kept outside the routing table.
ID allocator code inspired by my own code for altq and pf tags.
mostly hacked at the c2k4 hackathon, markus ok
