Working ping.
msafd: Added datagram flag to SOCK_RAW sockets
transport/* did some refactoring, added some printing.
Main thing: there is now a generic IP only header builder in rawip
that's
shared by udp and rawip.
afd: Make sure datagram sockets always select writable
Add some socket close infrastructure to kill associated active
polls
