Remove the M_ANYCAST6 mbuf flag by doing the detection all in ip6_input().
M_ANYCAST6 was only used to signal tcp6_input() that it should drop the
packet and send back icmp error. This can be done in ip6_input() without
the need for a mbuf flag. Gives us back one slot in m_flags for possible
future need. Looked at and some input by naddy@ and henning@. OK dlg@
