QUIC: separate UDP framework for QUIC.

Previously, QUIC used the existing UDP framework, which was created for UDP in
Stream.  However the way QUIC connections are created and looked up is different
from the way UDP connections in Stream are created and looked up.  Now these
two implementations are decoupled.
