udp: Rename UDP listening sockets

EPOLL_TYPE_UDP is now only used for "listening" sockets; long lived
sockets which can initiate new flows.  Rename to EPOLL_TYPE_UDP_LISTEN
and associated functions to match.  Along with that, remove the .orig
field from union udp_listen_epoll_ref, since it is now always true.
