The functional change here is that our code to stop
autoscrolling on certain events, particularly mousemove,
now only runs during system initiated autoscroll events.
If the user had been replying to a message, then the feature
to stop autoscroll was too aggressive.
This patch also starts to put more scrolling-related code
into viewport.js, which will hopefully prevent some code
duplication and give us a single place to control things like
stopping animated scrolls.

We also record the historical edits to the message in this JSON format:
[{"prev_content": "new test message 14", "timestamp": 1369157249},
{"prev_content": "new test message 13", "timestamp": 1369157118}]
but we don't actually do anything with the information as of yet.

This goes back to only scrolling by the size of the new
message, and it avoids scrolling in certain use cases.

This will make it automatically work if we add new tab
bar like things. The current version of ui.message_viewport_info()
is slightly broken; that's a separate fix.

The only known outstanding bug with this is that it doesn't properly
handle the updating of a message's highlighting/presence in a narrowed
view (e.g. in theory, a message should disappear if it is edited such
that its subject doesn't match your narrow or it no longer matches
your search). I think I'll just open a trac ticket about that once
this is merged, since it's a little hairy to deal with and kinda a
marginal use case.
Also it's not pretty, but that should be easy to tweak once we get the
framework merged.

Currently the interface for editing messages is limited to a
command-line API tool; it's great for testing with e.g.:
./api/examples/edit-message --message=348135 --content="test $(date +%s)" --site=http://localhost:9991 --subject="test"
The next commit will add a user interface for actually doing the editing.

The geometry used by within_viewport() is a little off to
begin with, but we don't want to check it at all in this
situation, because if the last messages falls out of the
viewport, we still want to scroll. The relevant thing
to check is that available_space_for_scroll exceeds zero.
(imported from commit a0a6f0d23db2eab8d9f22fc9ad523031cf7f7ec2)
The prior code was subtracting out the compose box from the
calculation of available_place_for_scroll, which didn't make
sense when the compose box is at the bottom of the screen
and you're scrolling the current message up. You could see
the symptom pretty clearly by seeing autoscroll stop exactly
the height of the compose box from the top.
(imported from commit cfceb85c8be80cca957ac4a3ad0bbf0de7425c48)
The .height() and .width() functions are actually pretty expensive
for the number of times we call them. The callers of within_viewport
already know the offset and height of the row, so we just pass them
in so the values don't have to be recalculated.
(imported from commit d1c077bd87463d695f0bbe337b6a8b04ac2d17ce)
Really, the "correct" way to do this is to undo "scrolltheworld", and
then just have a compose div that always lives underneath the message
list div. (This will also allow us to deal much more reasonably with
the whole "Is the composebox in focus" thing.)
In the interest of prototyping something more rapidly, though, we
adopt the somewhat more hackish approach, with the understanding that
much of it will probably be simplified later.

Messages are now explicitly condensed by our JS, which means that if
we run into some bug where our JS doesn't run, you still see the whole
message (rather than getting a clipped message).
(As of this commit, this can happen when you, e.g. are on the
Settings page and someone sends you a message.)
(imported from commit f3bec97800ea1852c80203e73552ee545fcc7e8a)
Previously, we were having this problem where:
* You narrow to something
* That causes message_list.js:process_collapsing to run on all of the
elements in the view, which changes some of their sizes
* That causes the pane to scroll and either push the content up or
down, depending (since stuff on top of where you were is now a
different size)
* That triggers keep_pointer_in_view, which moves your pointer
Moving process_collapsing into narrow.activate doesn't obviously
fix any of this, but it does seem to mitigate the issue a bit.
In particular, we (a) process it less frequently, and (b) process it
immediately after we show the narrowed view table, which seems to
reduce the raciness of the overall experience.
This does, however, introduce a regression:
* If you receive a long message when you're on
#settings, e.g., and then go back to Home,
the message does not properly get a [More] appended
to it.

This was apparently broken by the final revision of our fix to the
autoscrolling+narrow bugs, because it attempted to use jquery's
animation queues to restrict which animations were stopped, and this
doesn't seem to work.

Previously we were using message.display_recipient everywhere, which
is actually pretty confusing.

This is basically just the logical extension of the previous commit
for the case where the last thing we did was subscribe or unsubscribe.
This even magically updates when you subscribe or unsubscribe from
another window :).

This should fix the problems we've been having with out-of-order
message deliveries, and is also an important prerequisite for showing
historical messages.
(imported from commit 77a18a526bf8ec4f1f70b776ac8b7e189d00bcf4)
What was happening is that if you un-narrowed immediately after
receiving a message (e.g. because you just sent it), the autoscroll
animation from the zfilt table would still be running after you return
to the home view, resulting in the viewport being scrolled to an
apparently random point in the home view (even though the pointer was
still in the right place).
This cancels the autoscroll animations whenever you do one of:
(1) hashchange (e.g. to go to the settings page)
(2) select a message (covers narrowing/unnarrowing as well as keyboard hotkeys)
(3) mousewheel scroll
since those are basically the cases where we set the viewport
scrolltop directly.
Arguably this should instead be something where we somehow detect
which scroll events are triggered by what and cancel for any scroll
event not from the animation or rererendering, but that seems hard.

...rather than embedding them into index.html.
This is only acceptable for dev, but the next commit adds an alternative
mechanism for prod.
There isn't actually a manual deployment step here. However, this commit won't
work on staging / prod without the next one (since we don't serve
zephyr/static/templates in prod).

We also needed this when rerendering on append, so moving it into
_maybe_rerender allows the two places to share the code.
(imported from commit 027d99cae7864747cf1ec94c95e8ece495b5c907)
Previously, if the pointer was high on the page such that there was a
lot of empty space below and the render window was full (a situation
we could get into if we're following new messages arriving), a newly
recieved message would not be rendered even though it would have been
visible on the screen if we had done a rerender. Adding the
_maybe_rerender() call to the end of append() ensures that we don't
end up in this situation.
(imported from commit 925d3cc62e8221b42f1d5ff1788e99c7d07ccc24)
The message list data structure never had the rendered_idx values
initiatized except via _maybe_rerender (called when a message is
selected). For the narrowed message list for streams with no messages
yet, we didn't select a message (as there was none to select); the end
result is that msg_list.append() will never rerender because it tries
to subtract undefined from undefined and gets NaN in its test for
whether it needs to rerender.
So fix this by initializing _min_rendered_idx and _max_rendered_idx to
valid values for the empty message list (the closed interval from 0 to -1).
