cjs 8a449a258b Add net.inet.ip.allowsrcrt option which allows/drops all source 
routed packets. This currently defaults to `drop,' but once we
verify  that all applications that rely on determining remote IP
addresses for authentication are dropping the connection when they
see a source route option (not just disabling the source route
option), we can turn this back on and conform with the host
requirements.

thorpej 9df1988ac8 Implement the IP_RECVIF socket option: supply a datagram packet's incoming 
interface using a sockaddr_dl in a control mbuf.

Implement SO_TIMESTAMP for IP datagrams.

Move packet information option processing into a generic function
so that they work with multicast UDP and raw IP as well as unicast UDP.

details.  Also, fix a bug in TCP wrt SYN+URG packets.

thorpej 535abd80a2 Add a net.inet.ip.directed-broadcast sysctl as suggested by 
Darren Reed <darrenr@vitruvius.arbld.unimelb.edu.au> in PR #1227.
This change is slightly different than the one submitted by Darren in
that the DIRECTED_BROADCAST compile-time option will behave like it used
to so that existing configurations utilizing it won't have to change.

thorpej 4b359df8c4 Add net.inet.ip.forwsrcrt: if zero, the system will not forward 
source-routed packets.  Note this value is protected by kernel security
level; it can only be changed if securelevel < 1.
