udp: Create flows for datagrams from originating sockets
This implements the first steps of tracking UDP packets with the flow table rather than its own (buggy) set of port maps. Specifically we create flow table entries for datagrams received from a socket (PIF_HOST or PIF_SPLICE). When splitting datagrams from sockets into batches, we group by the flow as well as splicesrc. This may result in smaller batches, but makes things easier down the line. We can re-optimise this later if necessary. For now we don't do anything else with the flow, not even match reply packets to the same flow.
