cleanup vmd(8) includes and header files Lots of organic growth other the years lead to unnecessary includes (proc.h everywhere) and odd dependencies between header files. This cleans things up a bit to help with upcoming cleanup around dhcp code. No functional change. "go for it" mlarkin@

Filter out packets that are not IPv4. This code came from dhcp programs where this filtering was done in bpf but here vmd needs to make sure to not look at non IPv4 packets. OK florian@ and dv@

vmd(8): skip inspecting non-udp packets on local interfaces reyk@ imported packet.c from (I think) dhclient(8). In dhclient, the packets are already filtered down to just udp. This change has vmd skip a non-udp ip packet sooner when it's trying to determine if it is a dhcp/bootp packet that needs processing. The counters (seen, bad checksums, etc) for ip and udp packets are also removed as they aren't used by vmd. This only affects "local" network interfaces for vmd. OK mlarkin@

Add support for dynamic "NAT" interfaces (-L/local interface). When a local interface is configured, vmd configures a /31 address on the tap(4) interface of the host and provides another IP in the same subnet via DHCP (BOOTP) to the VM. vmd runs an internal BOOTP server that replies with IP, gateway, and DNS addresses to the VM. The built-in server only ever responds to the VM on the inside and cannot leak its DHCP responses to the outside. Thanks to Uwe Werler, Josh Grosse, and some others for testing! OK deraadt@
