      XMPP queued output & initial retooling of DB queue manager to support non-Notice objects. · 26fdf0c9
      Brion Vibber authored
      Queue handlers for XMPP individual & firehose output now send their XML stanzas
      to another output queue instead of connecting directly to the chat server. This
      lets us have as many general processing threads as we need, while all actual
      XMPP input and output go through a single daemon with a single connection open.
      
      This avoids problems with multiple connected resources:
      * multiple windows shown in some chat clients (psi, gajim, kopete)
      * extra load on server
      * incoming message delivery forwarding issues
      
      Database changes:
      * queue_item drops 'notice_id' in favor of a 'frame' blob.
        This is based on Craig Andrews' work branch to generalize queues to take any
        object, but conservatively leaving out the serialization for now.
        Table updater (preserves any existing queued items) in db/rc3to09.sql
      
      Code changes to watch out for:
      * Queue handlers should now define a handle() method instead of handle_notice()
      * QueueDaemon and XmppDaemon now share common i/o (IoMaster) and respawning
        thread management (RespawningDaemon) infrastructure.
      * The polling XmppConfirmManager has been dropped, as the message is queued
        directly when saving IM settings.
      * Enable $config['queue']['debug_memory'] to output current memory usage at
        each run through the event loop to watch for memory leaks
      
      To do:
      * Adapt XMPP i/o to component connection mode for multi-site support.
      * XMPP input can also be broken out to a queue, which would allow the actual
        notice save etc to be handled by general queue threads.
      * Make sure there are no problems with simply pushing serialized Notice objects
        to queues.
      * Find a way to improve interactive performance of the database-backed queue
        handler; polling is pretty painful to XMPP.
      * Possibly redo the way QueueHandlers are injected into a QueueManager. The
        grouping used to split out the XMPP output queue is a bit awkward.

      Quick hack to avoid breaking with geonames off when there's some old cookie state. This code's a little rough and tumble; any breakage halts JS execution and leaves the spinner going and no message submitted.
