Implement UDP control block support.

So far the udp_tun_func_t had been (ab)using inp_ppcb for udp in kernel
tunneling callbacks.  Move that into the udpcb and add a field for flags
there to be used by upcoming changes instead of sticking udp only flags
into in_pcb flags2.

Bump __FreeBSD_version for ports to detect it and because of vnet* struct
size changes.
