Steve Howell 3f06f28ad7 sending messages: Extract sent_messages.js.
This commit extract send_messages.js to clean up code related
to the following things:

    * sending data to /json/report_send_time
    * restarting the event loop if events don't arrive on time

The code related to /json/report changes the following ways:

    * We track the state almost completely in the new
      send_messages.js module, with other modules just
      making one-line calls.

    * We no longer send "displayed" times to the servers, since
      we were kind of lying about them anyway.

    * We now explicitly track the state of each single sent
      message in its own object.

    * We now look up data related to the messages by local_id,
      instead of message_id.  The problem with message_id was
      that is was mutable.  Now we use local_id, and we extend
      the local_id concept to messages that don't get rendered
      client side.  We no longer need to react to the
      'message_id_changed' event to change our hash key.

    * The code used to live in many places:
        * various big chunks were scattered among compose.js,
          and those were all moved or reduced to one-line
          calls into the new module
        * echo.js continues to make basically one-line calls,
          but it no longer calls compose.report_as_received(),
          nor does it set the "start" time.
        * message_util.js used to report received events, but
          only when they finally got drawn in the home view;
          this code is gone now

The code related to restarting the event loop if events don't arrive
changes as follows:

    * The timer now gets set up from within
      send_messages.message_state.report_server_ack,
      where we can easily inspect the current state of the
      possibly-still-in-flight message.

    * The code to confirm that an event was received happens now
      in server_events.js, rather than later, so that we don't
      falsely blame the event loop  for a downstream bug.  (Plus
      it's easier to just do it one place.)

This change removes a fair amount of code from our node tests.  Some
of the removal is good stuff related to us completing killing off
unnecessary code.  Other removals are more expediency-driven, and
we should make another sweep at ramping up our coverage on compose.js,
with possibly a little more mocking of the new `send_messages` code
layer, since it's now abstracted better.

There is also some minor cleanup to echo.resend_message() in this
commit.
