rerender_messages() does extra work such as making rerendering in narrows
safe, as well as updating recipient bars. That should be the only valid entry
point for rerendering individual messages

Previously topics weren't being highlighted at all and messages had their
highlighting persist across different narrows (because we were only checking
whether the message object had a match_content property, not whether it should
currently be used).

Now that we no longer use tables for our message list, we can
more logically group messages together.

This experiment has been disabled for everyone for a while: if we
bring something like this back, it is not likely to be exactly the same,
and will be different enough to require a different implementation.
As it is, the summarization code was making a few code paths (rendering
especially) more complex, and is worth removing for simplicity's sake.

Change the offset to hold of the selected message as an offset from the
top of the screen. Then use the current offset and scrollTop to compute
the new scrollTop.

The message_rendered.zulip event fires after a new messages was rendered
but before it is added to the DOM. This allows javascript components to
change the display of a message before it is added to the DOM.

I'd check for bookends, but not daterows. Now, we just check if we can get
a message id out of it, rather than excluding specific types of rows.

Trying to condense messages when they are not yet visible just
leads to wasted effort and wrong results.
This commit makes it so that current_msg_list always points to a
visible list, so the code related to message rendering knows when
to call ui.condense_and_collapse(). For activating narrows, we
now let rendering handle the condense/collapse case.
The home view situation is a little trickier, because we render
new messages in the home view even when we're inside inside of a narrow,
presumably to make it fast to switch into the home view. When
we actually go back to the home view, we need to sweep for messages
that might need to be condensed, since they have been originally
rendered while the home view was not visible.

I renamed ui.process_condensing() to ui.condense_and_collapse(),
and, more importantly, it now takes a list of elements, not a single
element, which allows us to do some computations outside the loop.

When we add starring of historical messages, they'll get added to the
home view (since we don't filter them out), which isn't a big deal --
but we don't want to make an inaccurate claim that the user subscribed
to this stream and then unsubscribed.
This should most properly be handled by filtering server-side, but at
the moment our lack of an index on UserMessage.flags makes that
impractical from a performance perspective.

Use the new count_full_messages_between instead of subtraction in
message_list_view.append. By finding a count higher than it should be
when summarized messages are present, it didn't add new messages until
the pointer moved under certain conditions.

Summary blocks can contain hundreds of messages. When the rendering window
code didn't take this into account, it would lead to all kinds of
unpleasant behavior when you scroll.
Trac #1888
Unfortunately, this replaces a subtraction with a function that iterates
through all the messages.

The main user-facing feature here is that users can open narrows
in new tabs or windows. Internally, it makes the HTML more semantic.
One consequence of making these elements into actual anchor tags
is that clicking on them no longer triggers this logic to
close the compose box when you click outside of it:
// Unfocus our compose area if we click out of it. Don't let exits out
// of modals or selecting text (for copy+paste) trigger cancelling.
if (compose.composing() && !$(e.target).is("a") &&
($(e.target).closest(".modal").length === 0) &&
window.getSelection().toString() === "") {
compose.cancel();
}
Instead of patching the above code, I elected to just call
compose.cancel() explicitly in the click handlers for the links
themselves.
We are gonna try to clean up the compose-box behavior globally soon.

Instead of collapsing muted messages, just hide them altogether
in view where it makes sense to hide them.

If the date_row is between two messages, it tells you when the message
below was sent, but not when the message above was sent--for that you'd
either have to click on a message or keep scrolling up. This is especially
annoying when there are sometimes gap days on a particular stream (you shouldn't
assume that the message above is simply from the previous day).
This adds the date of the previous message (the time above) to the date_row.
