Add TRANS(Listen) function to re-enable specific listen sockets

This will allow a server to disable listeners by default and then
let later configuration re-enable them. In particular, this lets the X
server disable inet and unix listen sockets by default while still
providing a '-listen' command line option to re-enable them later on.
