For greater clarity and in preparation for making message events be
processed more like how we process other events, we are changing:
data => event_template (for the input event we're processing)
event => user_event (for the event sent to a user's clients)
event => notice (for the missedmessage notifications)
(imported from commit 30c76c3588ebe2ac44e27e17a39df4a1403979cb)
This is a lot simpler and eliminates a possible failure mode in the
data transfer path.
(imported from commit 19308d2715bbd12dc9385234f1d9156f91bdfae0)
This returns us to the original situation where we're not in the
practice of doing database fetches for UserProfile objects in the
Tornado workflow, which should make our performance no longer
alarmingly degrade when memcached gets flushed.
(imported from commit 3580737604c13c9989f120a2242ad4c3eab6e1d1)
This does result in a few more rabbitmq events to be processed (though
a negligible number compared to what we already do), but it saves a
database query from inside Tornado whenever we occasionally have a
cache miss looking up the UserProfile, which is far more important.

When we edit a message, send out UserMessage flags to the recipients.
This sets the stage for making sure that changes related to
user-specific alert words or mentions get sent out to users.

Unbundle the push notifications from the missed message queue processors
and handlers. This makes notifications more immediate, and sets things up
for better badge count handling, and possibly per-stream filtering.
(imported from commit 11840301751b0bbcb3a99848ff9868d9023b665b)
It makes the event queue return all messages on public streams, rather
than only the user's subscriptions. It's meant for use with chat bots.
(imported from commit 12d7e9e9586369efa7e7ff9eb060f25360327f71)
The do_send_messages() populates the user_presences data structure
for process_new_message(), so that Tornado code never needs to hit
the database or memcached to get the user presence info.
(imported from commit 194aeaead8fa712297a2ee8aff5aa773b92f1207)
This reduces the number of memcached calls we make in our time-
slice-limited tornado event handler.
(imported from commit 8903ce4ac754ba82d57e04d1b0356be7533edee2)
This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
