udp: Handle errors on UDP sockets
Currently we ignore all events other than EPOLLIN on UDP sockets. This
means that if we ever receive an EPOLLERR event, we'll enter an infinite
loop on epoll, because we'll never do anything to clear the error.
Luckily that doesn't seem to have happened in practice, but it's certainly
fragile. Furthermore changes in how we handle UDP sockets with the flow
table mean we will start receiving error events.
Add handling of EPOLLERR events. For now we just read the error from the
error queue (thereby clearing the error state) and print a debug message.
We can add more substantial handling of specific events in future if we
want to.
