The message_viewport_info() function encapsulates our logic
around the compose box and other elements blocking the viewport,
so viewport.js seems like a more logical home for it. It also
makes ui.js, one of our largest modules, a little bit smaller.

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().

We are moving back to a barnowl-ish scrolling algorithm for
the arrow keys, where when you have a message selected toward
the bottom of the screen, hitting down arrow and up arrow
effectively puts the originally selected message at the center
of the screen. In order to avoid unnecessary scrolls, we
are making it so that you can move the pointer closer to the
edges.

`current_msg_list.get(id)` and `rows.get(id,
current_msg_list.table_name)` are not interchangable in terms of
checking for whether we have a message. The former checks whether
the message is in the current message list while the latter checks
whether the message is in the current message list and currently
rendered. `message_edit.end` only operates on rendered messages.

Previously, if you didn't have a message that someone else had edited
in your message list, you would get an exception because we weren't
checking whether we actually had the message or not.

Before this fix, the code would restrict the pointer to be above
either the 1/2 mark or 2/3 mark of the page, depending on your
scrolling direction. This fix makes it so that the system leaves
your scroll and pointer alone when between the 1/5 mark and 4/5
mark. This means the user can read more messages on the screen
at a time before getting paginated.

Re-focuses on the compose box after a send, under these conditions:
1) narrowed to stream+subject -or- responding to PM/huddle
2) compose was initiated by clicking on a message or hitting "r"/"enter"
3) cursor has not moved since you've started the composition
Additionally, if you are thus narrowed, we will move your cursor when you've sent
a message to that message, assuming that such a message initially appears visible.

This change fixes the barnowl scrolling so that the ratios of
1/5, 1/2, and 2/3 are all relative to the visible viewport.
The core part of the fix is that we need to call
ui.message_viewport_info() to get the correct offsets for
the top/height of the actually visible viewport Because
this function is fairly expensive, I didn't want the
helper functions needlessly re-calling it. I could
have passed the helper functions the structure, but at
that point it was simpler to inline their functionality.

The reply-to autoscroll was using a flag that was redundant
to suppress_scroll_pointer_update and then updating it prematurely,
which caused the pointer to move when you clicked on a message to
reply to it. Now the pointer goes to the message you replied to.

The main point of this fix is to move some more scroll-related code
into viewport.js, but it also fixes a bug where the size of #main_div
was not accurately representing the full height of the message list.
Making the calculation more accurate narrows the window where we
do pointer adjustements on mousewheel moves.

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.

Currently the interface for editing messages is limited to a
command-line API tool; it's great for testing with e.g.:
./api/examples/edit-message --message=348135 --content="test $(date +%s)" --site=http://localhost:9991 --subject="test"
The next commit will add a user interface for actually doing the editing.

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.

The problem is that if you load a browser window in a stream narrow,
add_message_metadata will be called for the messages in the narrowed
view before it is called for the messages going into the main view
(thus inserting them into all_msg_list), resulting in duplicate
copies of messages.
This would be mostly OK except that we call
process_message_for_recent_subjects inside add_message_metadata, and
that function assumes it is only called once on each message
(otherwise it'll double-count the message).

This refactoring basically splits off two functions from update_unread_counts(),
which then becomes a simple three-liner.
The function get_unread_counts() is extracted, and it's purely functional
computation. It paves the way for a more pull-based approach to getting "unread"
counts, where other parts of the program can just call it to get values as
needed without worrying about side effects. It is staying in zephyr.js for
now.
The other function is stream_list.update_dom_with_unread_counts(), which
has a new home in stream_list.js. It handles all the DOM manipulation
aspect of unread counts in the left pane, mostly by delegating to smaller
functions within stream_list. Some of those smaller functions can now
be turned into private methods FWIW, but I'm not sure it's worth the
trouble.

This is a prefactoring to eventually eliminate the home_unread_messages
global variable. More commits to follow.
In order to set up process_loaded_for_unread() not to modify
global variable to get its job done, we want to pull it out of
add_messages(), so that add_messages() doesn't have to pass back
state to the 9 different places in the codebase where it's called.
There are only 2 places where process_loaded_for_unread() get
called after this commit.
In order to facilitate pulling up process_loaded_for_unread(), I
made it so that the contract for add_messages() was to accept
already-hydrated messages. This way I could hydrate the messages
before calling process_loaded_for_unread() without have to
worry about double-caching them in add_messages. This will
slightly improve performance, but it was mostly done for code
clarity.

don't change often, though, so we can just cache them and recalculate
