Introduce ip_fastforward and remove ip_flow.

Short description of ip_fastforward:

 o adds full direct process-to-completion IPv4 forwarding code
 o handles ip fragmentation incl. hw support (ip_flow did not)
 o sends icmp needfrag to source if DF is set (ip_flow did not)
 o supports ipfw and ipfilter (ip_flow did not)
 o supports divert, ipfw fwd and ipfilter nat (ip_flow did not)
 o returns anything it can't handle back to normal ip_input

Enable with sysctl -w net.inet.ip.fastforwarding=1
