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().

Because of spacing issues in the right sidebar, the unread counts
appear to the left of the person's name, not the right.
It's kinda awesome that this is only 20 lines of code.

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.

I removed references to the following:
on_custom
custom_message
current_message
show_custom_message()
clear_customer_message()

receive a msg parameter any more.

We could get into this situation when someone is doing a search and
someone else edits a message while the results are still loading.

`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.

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.

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.
(imported from commit 98f6319bf63181dd331e037ac20a0c15518725ea)
When you make a call to set_message_position(), you already
know that the pointer is gonna be onscreen, so set the flag
to suppress scroll pointer updates. This should be faster and
also avoid future confusing bugs where recenter_view() and
keep_pointer_in_view() run for the same event.
(Both callers to recenter_view pass in the selected message,
and then the calls to set_message_position() set the scrollTop
so that the selected message shows onscreen.)

This also changes the color for the blink effect when you
get private messages. For simplicity sake, we use the
same color for private messages and mentions.

Previously it could return an array or boolean, and this inconsistent
interface had several latent bugs where consumers of the API only
considered it returning one or the other type.
This also fixes a specific bug a user triggered by being narrowed to
nothing (/#narrow) and clicking in the compose box.

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.

Currently, this is accessed by clicking anywhere in the sidebar region
other than the text of the person's name itself, which does the
existing narrow behaviour. Later we can make it do something clever
with hovering pulling out the popover or something, but that's
potentially a significant design project I think this is good enough
to be useful.

We had a couple places where autoscroll would
mysteriously midway through scrolling, and it
was because scrolling generates mousemove
events.

Treat "mentioned" messages like "starred" messages for narrowing.
Lots of ugly copy/paste here. There might be opportunity for
some cleanup in places.

The bug we experienced here was that if you loaded the page in a
narrowed view, and then un-narrowed before the first block of messages
for the home view arrived via load_old_messages, then
narrow.deactivate() would re-select ID -1 in home_msg_list. This ends
up calling recenter_view() on the message, which in turn tries to
access the message with message id -1, which fails.
We do sometimes re-select a message ID in order to recenter the view
properly when we prepend messages to a message list, so we can't make
this always a nop; instead we add a check for id -1 in the
message_selected.zephyr event handler.

There was an off-by-one error in how we determine when
the message list was scrolled all the way to the bottom,
and this undermined our handlers for page down and scrolling

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.
