Extract network datagram endpoint common facilities
...from the UDP endpoint.
Datagram-based transport endpoints (e.g. UDP, RAW IP) can share a lot
of their write path due to the datagram-based nature of these endpoints.
Extract the common facilities from UDP so they can be shared with other
transport endpoints (in a later change).
Test: UDP syscall tests.
