rG3d2041c0353d: raw ip: merge rip_output() into rip_send()

Summary

While here, address the unlocked 'dst' read. Solve that by storing
a pointer either to the inpcb or to the sockaddr. If we end up
copying address out of the inpcb, that would be done under the read
lock section.

sys/netinet/raw_ip.c
434	Q: why do we store reference instead of just saving the value?

sys/netinet/raw_ip.c
434	At this point inp isn't locked. On the copyout it will be locked. Well, inp_faddr can not change, I believe. But reading value out in the locked section, kinda more cool.
