This was biting us before when the user would leave a narrow before a
get_old_messages call associated with it finished. Specifically,
search.maybe_highlight_message() would assume a message was in the
DOM when it wasn't any more.
We also have to hide the 'loading more messages' indicator when
reseting the 'load more' status because otherwise it wouldn't get
hidden like normal in the load_old_messages() continuation, causing a
load_more_messages() not to fire when re-entering a narrow.

If the user scrolls super fast, our scroll handler might not catch
the user passing by some messages.

We create a circular reference between handler functions and our
wrappers for them so that we can pass the wrapper to jQuery.off when
users pass the original handler to us. This reference-counting
system can't break all the circular references we create because
users can unbind event handlers without explicitly naming the
handlers they want to remove (they can remove all bindings on an
element, for example). For now, we hope that this memory leak isn't
too bad.
(imported from commit 9615b5761b4b09ca7ca52c0d847e9b83330373fa)
Previously, we couldn't actually unbind some event handlers. The
problem was that when a user called $.off(events, handler), the
passed handler wouldn't match any that were actually bound because
the handler that was actually bound was our wrapper.
This bug specifically caused the handlers for our idle timers to
never be unbound, effectively never cancelling them.

We will need this for removing event handlers. This will
unfortunately create a memory leak, but we'll partially deal with
that later.

It's closer to a presence query than an update, and more importantly
this moves this out of Tornado -- previously Tornado was spending at
least 3ms per recipient on messages sent to the MIT realm fetching all
this data to return back to users. This should save around 100ms per
message sent to a popular stream the MIT realm -- but more
importantly, each such event is 100ms during which Tornado is not
processing other messages.

It's pretty confusing if this doesn't change. In some other world we
could update the fade, but since we're currently only fading on reply,
I think it would be weird to update the fade when you're picking a new
recipient.

Previously, we compared the recipients of messages to the message that

This commit changes the code to instead track what you faded by,

We treat these exceptions the same way we treat fatal errors: report
the error message to our server and then allow the exception to reach
the top level.
We could also override document.onerror, but don't. There are a
couple of ramifications of this:
* Exceptions caused by event handlers directly attached to DOM
elements aren't handled
* Exceptions caused by code at the top level that triggers an error
(such as parse errors in our Javascript files) aren't handled
The reason we don't override document.onerror is because the
document.onerror handler has a limited interface and doesn't receive
the exception object. It only gets the message, file, and line
number of the error. Additionally, exceptions that we allow to
propogate out of blueslip trigger an onerror event when they're never
caught. In order to avoid handling the error twice (once by blueslip
and once by the onerror handler), we'd have to encode the fact that
the error has already been handled in the error message, which is
pretty ugly.

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.

Now that Zev's message list branch is merged, there's no longer a
performance penalty for loading these old messages, and it improves
our narrowing performance to have them loaded.
This code is slightly different from the original commit
93d47710891cfc4db9fa00beaa5ccd10113aa1c3 since the way to access the
first element in the message list and the API for get_old_messages
have changed since then.

This will hopefully make stream privacy more noticeable. We still don't

We were previously having an issue where the tutorial could
be pre-empted if you got a few messages while you were first
logging in.
I have some reservations about this being slightly fragile, and a
better approach might be to just have a bit that we use to determine
whether or not you've already seen a tutorial. (Or potentially that
checks whether or not you've ever sent a message.)

The issue, prior to this fix, is that the presence list actually
gets drawn *on top of* our "more messages" popup, which is ugly.
(Toggling the z-index on either or both of them did not seem
necessarily to matter, but that's probably because z-index
is subtler than I understand.)

This was most often noticed with the tutorial bot.

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).

This is in response to the following bug report by Evan Broder:
FYI, it looks like if I accidentally tab to the "Formatting" link and
hit enter, it erases the message (and replaces it with a reply to
whatever the selected message is, I think?)
This is subtle and here's why: Suppose you have the focus on a
stream name in your left sidebar. j and k will still move your
cursor up and down, but Enter won't reply -- it'll just trigger
the link on the sidebar! So you keep pressing enter over and
over again. Until you click somewhere or press r.
Net-net though, I think it's a change worth making, because
it's good for keyboard accessibility.

Previously we did the equivalent of a $('.message_comp').child('input'),
which does not search beyond the first level.
In addition, using a comma in a selector is essentially an AND, which
means the narrow search only applied to elements of the 'input' class.
So when debugging we saw a bunch of elements being selected and that hid
the bug for a bit.
Now we do a .find instead which will ensure we blur the correct
elements.

The most expensive part of adding the display time to messages is
calling time.toLocaleDateString() and time.toLocaleTimeString().

before the re-render.
