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.

Previously, we saved the current_msg_list selected id and then
restored it as the home_msg_list selected id, which could result in
the home view loading to the wrong place.
This takes some already bad code and makes it even more in need of
refactoring, but it does fix a pressing bug. We should definitely
refactor both:
* the top of narrow.js
* the save/restore code in reload.js
after this, though.

This does have a small functional change of using use_closest even for
the current_msg_list.last().id case, but that's harmless; and it does
reduce a lot of code duplication and confusing logic here.

This implementation is somewhat hackish in large part because I think
we're going to be wanting to redo the get_old_messages API somewhat
soon, and this may naturally become a lot cleaner as a result, but
this isn't a lot of code and fixes#2235 part (A) and substantially
mitigates #1510.

Even in the case where we are running embedded narrows,
we want narrow.operators() to return new-style operators
that you get with Filter objects, so that callees do
not need to support the legacy tuple format.

Change the offset to hold of the selected message as an offset from the

the new scrollTop.

Our logic for unnarrowing when messages were read during the narrow
did not properly use the then_scroll option and thus actually set the
scroll position when they selected a new message. This was
accidentally prevented from being a big problem by the incorrect
scrolling logic that was fixed by:
Only preserve_pre_narrowing_screen_position when preserving pointer.
which caused the browser to scroll _back_ to close to the correct
scroll position (but not the intended scroll position -- it would
usually be a little bit off).

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.
(imported from commit 4da2d278a4353e9e0c2b98cbf8c9dd03b06cd59b)
There are now 2 cases for narrowing:
1. We narrowed, but only backwards in time (ie no unread were
read). In this case, try to go back to exactly where we were before
narrowing. This behavior is unchanged.
2. We read some unread messages in a narrow. Instead of going back to
where we were before the narrow, go to our first unread message (or
the bottom of the feed, if there are no unread messages). This is new.
This means that after catching up through the sidebar, on returning
home you'll be at the bottom of your feed.
Searching for the first unread message in a message list with 40,000
messages only takes 17ms according to:
function timeit() {
var t0 = new Date().getTime();
_.find(current_msg_list.all(), unread.message_unread);
var t1 = new Date().getTime();
console.log('Find first unread: ' + (t1 - t0) + ' ms');
}

I'd also like to add a database table to actually store the values

inspection, but for now, grepping logs+statsd is good enough.

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.

If we load a browser window in a narrowed view and then un-narrow
before the home message list has loaded, we end up attempting to
select message ID -1 from home_msg_list even though it is empty,
triggering a traceback.

Narrow.activate was called without an options object in one
obscure location. I'm not sure how it's actually triggered,
since all searches seem to go through the typeahead path with
the "Search for x" option, but someone managed to do it.

I switched narrow.by_subject and narrow.by_recipient to use the all_msg_list
instead of current_msg_list, since we wanted to be able to narrow to messages
specifically not in the current_msg_list. However, in searches which revealed
old messages outside the range of all_msg_list (which only has a single contiguous range),
this broke narrowing.
Let's use msg_metadata_cache instead.

Displays a notification above the composebox in cases where the message
is not visible (further down), or where it's outside the current narrow or search.
It also offers a link to the appropriate narrow when it makes sense, and offers
timetravel when appropriate. There is currently a bug with timetravel (and you can
see this when using the popover menu) that makes "narrow to messages around this time"
not work for muted messages.
This resolves Trac #1518.

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.

I'm trying to move well-isolated methods out of narrow.js, so that
narrow.js is more strongly focused on UI/ajax interactions and
big, heavy lifting stuff. The logical home for parse/unparse
seemed to be Filter, and they brought along two private methods
with them. The big code moves involved trivial follow ups
like s/exports/Filter/.

To get to the bottom of the too-much-fading regression,
it was necessary to clean up the code, which was overly
complicated by multi-purposed functions.
The API for compose_fade now has these functions:
set_focused_recipient
start_compose
clear_compose
update_message_list
update_faded_messages
Internally there is now a notion of "normal display",
so e.g. when you want a normal display, we call
_diplay_messages_normally() internally, which removes the
faded/unfaded classes from all messages.
(imported from commit 7eb2b0a163f29d9ebae26661f432fecc7c331e4c)
The compose_fade has three public exports:
set_focused_recipient
unfade_messages
update_faded_messages
All code was pulled directly from compose.js, except for the
one-line setter of set_focused_recipient. The focused_recipients
variable that used to be in compose.js was moved to compose_fade.js,
hence the need for the setter.

In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.
Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.
Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).
One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
