It's possible for selected_message_id to not exist in zhome. For
instance, when you open the page to a narrowed URL, there is a race
between loading the narrowed messages and loading all your
messages. If the narrowed message request completes first, it will
update selected_message_id to your initial_pointer if the latter
happens to be among the narrowed messages. Even if it is not, you can
select a message by clicking on it before the zhome request finishes.
Then the old code would never add that selected_message_id to the
zhome table, so it wouldn't show up in the Home view or if you
re-narrowed.
I'm pretty sure there are still cases where the selected_message_id
might be outside the range of messages in zhome, in which case adding
to zhome might put old messages at the bottom. I observed this twice
on staging but was unable to reproduce it consistently.

We suspect that these seem to be causing a regression where scrolling
in narrowed views gets really sluggish, but we haven't totally been
able to figure out why since it's challenging to reproduce locally.
(It currently manifests itself on staging but not prod.)
So for now we'll back them out. Here's the full set of things:
Revert "Cause update_floating_recipient_bar to get called less frequently."
This reverts commit a6c1518c4001a2dde44d7b512236795da3ccd351.
Revert "Remove double-scroll in un-narrowing code."
This reverts commit 3dde6c27ffa1e8afa1a084b1b2baee3bc0512962.
Revert "Reset our scroll position if we change our hash to "#"."
This reverts commit 925b44d770c96dafaabebc9e0114f9a3b8f53c4d.
Revert "Properly update floating subject bar when you are at top of page."
This reverts commit 6633cc8a81aedcbb31b30d7c1f27816f8808c700.

Putting update_floating_recipient_bar in the old location caused it to
be called on every single keypress, which is unnecessarily
expensive. Instead, just call it once when we think we might actually
need it: after initiating a narrow.

select_message_by_id with then_scroll: true already recenter_views
on the selected message; no need to also call scroll_to_selected.

Changing the hash to "#" causes Chrome to jump to the top of the page
on Mac OS X. This commit doesn't actually fix any bug, but it
is necessary for my *next* commit, where otherwise you'd have to
ensure that the scroll code came *after* the hashchange code.
(imported from commit 925b44d770c96dafaabebc9e0114f9a3b8f53c4d)
There's this very edge-case issue which is: if you go to the top of
the page and narrow to something other than the top message, the
floating subject bar does not update.
Why? Well, the way that the narrowing code works is that it sets up
narrowing and then calls
select_message_by_id(target_id, {then_scroll: true});
so that our selected message is in the view.
This in turn calls select_message, which calls recenter_view as
appropriate. This usually causes a scroll action, which in turn causes
the floating recipient bar to be updated.
But when we're at the top of the page, recenter_view doesn't need
to scroll at all! So the bar remains un-updated. Here we explicitly
update it to guard against that case.
This fixes Trac #651.

I don't view this as a complete solution to
Trac #466 - Make the fact that you are narrowed more apparent,
but it's a start.
(I think a real solution would have to give you something that
helps you make the determination of "Is this view narrowed?"
when you come back to your computer, and this animation does not
help you do that.)

This commit just moves around some lines so that the code that
hides the main view and shows the filtered view, or vice versa,
are together so that it's easier to reason about the sequence
of things that's happening.

This used to be a button that let us un-narrow, I guess.
A git grep for it after this commit turns up no actual
references to it.

And change the color to a more thematically appropriate blue.
The shadow pointer is sort of confusing; we should really provide some
different sort of indication that your pointer is potentially moving
on narrow-and-unnarrow. (I think my fade-in-fade-out later in this
commit series is a not-bad first crack at this.)
Resolves Trac #472 - Dual pointers in narrowed view can be confusing
(imported from commit 2450517d99de85ade1c0e98c5510b59e70282451)
If you narrow to a view that only has one or two message, sometimes
the grey box gets cut off and doesn't go to the bottom of the
page. This fixes that.

The initial rationale for hiding the floating recipient bar
was that it duplicated information that was in the "narrowbar".
Now that this no longer exists, let's *always* show the
floating recipient bar.
(Yes, there is some duplication of this information in the
search area, but I think the situation is fundamentally
different now and would basically like to see it everywhere.)

Alternatively the server could return a successful result with an empty list of
messages. But I prefer the solution in this commit, because it would allow us
in the future to warn the user about the problem. It does allow users to
determine if a given stream exists, but we haven't tried to hide that
information so far.

It's cleaner if the filtering code recognizes only one value.
We can add this back in by converting in the parser.

Show the buttons iff
- the search input is focused,
- the search input has non-empty contents, or
- we are narrowed.

We don't require that the parsed form be lower case; that's handled by
narrow.activate. However we unparse as lower case, in order to give the user a
hint that matching is not case sensitive.

Also removed .show()s for the alert on does-not-exist and not-subscribed, where
a blank error would display. This should fix the underlying issue with #166:
that hiding the composebox before send_message() was called would hide server
errors.

If you have a lot of subscriptions that you're trying to modify,
jumping back up to the top of the page is very disruptive. We still
show the success message, which has the effect of scrolling the page
and is thus surprising, but that's better than the user completely
losing their place.
We do need a story for informing users about failures to subscribe or
unsubscribe, though. We currently jump back to the top so they can
see the error, but that's not optimal.
