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.

Have narrow.activate() user filter.operators() to produce
operators that have operand/operator fields, so that its callees
don't need to be backward compatible with the tuple format.

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.

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).

I think that this will fix the issues we've been having with
hashchange.save_narrow() screwing up the scroll position in the page.

Features:
* Only shows messages in the narrow
* New messages in the narrow will arrive as they are sent
* Works even for streams you're not subscribed to
* Automatically subscribes you to a stream on send
* Doesn't update your pointer
* All searches etc. automatically have the narrow added

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.

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
that we get out of this and our send message requests for future
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.
