    Log Message:
    ircd: stop retrying the send queue of a closed connection forever

    Queue_Send() re-arms itself on a 100 ms timer while a socket won't accept
    more data. User_Quit() closed a local user's socket without purging its
    send queue, and Socket.send() on a closed socket fails without throwing, so
    the drain kept re-arming: every user who disconnected with output still
    queued (typically a ping timeout on a client that had stopped reading) left
    a 10 Hz timer running for the life of the process.

    Those orphans accumulate. On cvs they reached about 70 timers (about 825
    events per second) within a day, and after 5.5 days the callback engine was pinned at 100% of a core, could no longer answer PINGs in time, and every linked server dropped it.

    Queue_Send() now purges and returns when the socket is no longer connected, which covers every path that closes a connection with output pending, and User_Quit() purges the local user's queues as the server quit path already
    did.

    exec/tests/ircd/sendq.js covers the 100 ms back-off on a stalled socket, the immediate continuation of a partial send, and dropping (not retrying)
    output left on or queued to a closed socket.

    Fixes #1289
