Implement ALPC port abstraction and implement DNS resolver port (#558)

Browse Source 
This PR introduces an abstraction for ALPC ports to make them easier to
manage in the future, and implements the DNS resolver port, at least
enough to get host address queries working.
There's a lot of code in this PR that I'm not very confident about, so
don't hesitate on the feedback 😄
