The core simplification here is that zephyr.js no longer has:
* the global home_unread_messages
* the function unread_in_current_view() [which used the global]
The logic that used to be in zephyr is now in its proper home
of unread.js, which has these changes:
* the structure returned from unread.get_counts() includes
a new member called unread_in_current_view
* there's a helper function unread.num_unread_current_messages()
Deprecating zephyr.unread_in_current_view() affected two callers:
* notifications.update_title_count()
* notifications_bar.update()
The above functions used to call back to zephyr to get counts, but
there was no nice way to enforce that they were getting counts
at the right time in the code flow, because they depended on
functions like process_visible_unread_messages() to orchestrate
updating internal unread counts before pushing out counts to the DOM.
Now both of those function take a parameter with the unread count,
and we then had to change all of their callers appropriately. This
went hand in hand with another goal, which is that we want all the
unread-counts logic to funnel though basically one place, which
is zephyr.update_unread_counts(). So now that function always
calls notifications_bar.update() [NEW] as well as calling into
the modules unread.js, stream_list.js, and notifications.js [OLD].
Adding the call to notifications_bar.update() in update_unread_counts()
made it so that some other places in the code no longer needed to call
notifications_bar.update(), so you'll see some lines of code
removed. There are also cases where notifications.update_title_count()
was called redundantly, since the callers were already reaching
update_unread_counts() via other calls.
Finally, in ui.resizehandler, you'll see a simple case where the call
to notifications_bar.update() is preceded by an explicit call
to unread.get_counts().

When determining if desktop notifications are enabled, we can check whether
there is a "window.bridge" element.
Now when it comes time to actually send out notifications, we can just test
again for the existence of "window.bridge" and if so, shunt the data over
it.

Most of the model logic pertaining to unread counts had been in
zephyr.js, along with a couple global variables. Now the code
is encapsulated in unread.js. It was a pretty straightforward
extraction with some minor method name changes. Also, a small
bit of the logic had also been in stream_list.js.

This fixes a pretty subtle bug where the window-focus handler
wasn't updating the unread counts in the title, but it was
hard to notice, because as soon as you moved the mouse, the
problem fixed itself.
Apart from fixing the bug, this patch eliminates the expensive
mouseover handler, which is a big win.
The fix to the window-focus involved some unrelated cleanup. I
decoupled update_title_count() from received_messages(), as the
former method will probably live somewhere else soon.
Also, in order to get window-focus to update the title count,
I went pretty deep in the stack and added a call to
update_title_count() inside of update_unread_counts(). This
fixes window-focus as well as restoring that behavior to
code paths that were calling received_messages().
You'll see that call to update_title_count() is now adjacent
to the call to update_dom_with_unread_counts(), which is
fairly sensible, but then are calls to similar methods like
notifications.received_messages() that happen higher up in
the call chain, which seems kind of inconsistent to me. I
also don't like the fact that you have to go through a
mostly model-based function to get to view-based stuff, so
there are some refactorings coming.

Previously we never sent desktop notifications when the browser was
focused, even if the message appeared offscreen. After this commit
there are only a few cases when PM or other notifiable message doesn't
trigger a desktop notification:
(1) You sent it yourself
(2) It was onscreen when it arrived while your Humbug window had focus
(imported from commit e381c02c0e6794594d6934f57249a11ba2a88210)
This is trying to make the logic flow clear -- e.g. we check once, at
the beginning, for whether the message is notifiable, and the checks
for whether the various notification settings are enabled are more
parallel.

This decouples from Chrome notifications, which gives us cross-platform
support in at least modern browsers.
We log this action so its replayable in our message logs.
This implements the model change indicated by the previous schema commit.

We test if the user supports sound in their browser, then determine which
sort of sound their browser supports.
When, whenever we show a desktop notification we also play a sound.

We've been noticing a long delay between switching to a window with unread
messages and the time that those messages actually appear. This got much worse
around the time we added Notificon.
Our hypothesis (supported by some testing) is that the work done by Notificon
in creating a <canvas>, drawing into it, serializing it to PNG, etc. is using
up some quota of background operations that would be better spent rendering
messages.
Switching to precomputed images should mitigate this problem.
Resolves#896.
May resolve#882 to our satisfaction.
