Summary blocks can contain hundreds of messages. When the rendering window
code didn't take this into account, it would lead to all kinds of
unpleasant behavior when you scroll.
Trac #1888
Unfortunately, this replaces a subtraction with a function that iterates
through all the messages.

When we call rerender() on MessageList, it is usually because
something big has happened, so it's reasonable that the pointer
may now be invalid. As an example, the old pointed-to message
may been removed from the home view. We have always just
moved the pointer under the hood, but now we do it in a way
that doesn't generate spurious blueslip errors.
(imported from commit d399a101f36b744a423ea7da80dda8352440c6c9)
This fixes a blueslip error where we were trying to add the same
message into a MessageList twice. Muting complicates our duplicate
detection, because empty() can return true even when we already
are storing messages that just aren't shown (because of muting).
The name empty() should probably be fixed in light of muting,
but filtering with self.get() is not really a problem here.
(imported from commit 83b0890471c9a0aa21996f3d0d3be4a238f23e65)
With the muting/hiding features, it has become the case that
this._hash can have entries that don't map to actually visible
rows, so this.get() can return true on an id that shouldn't
actually be selected, causing downstream code to explode. Now
we call this.closest_id() regardless of whether the hash is
populated, to be safe, but then we still call blueslip.error
if the pointer moved.

Instead of collapsing muted messages, just hide them altogether
in view where it makes sense to hide them.

I moved code into MessageList to further encapsulate details
of filtering. The MessageList instances should be their own
gatekeepers for what messages they care about.

(The approach has been simplified to look for summary_row in
the DOM, which makes muted and summary features work off the
same code.)

This change would allow anyone in the realm to set a topic for a "no topic"
message. As soon as the message topic is set, only the sender can change it again.

Once you enter a view, the last n messages will be exempt from
summarization, to give the users a little more context. Any
subsequently arriving messages will also be exempt.
We will try n=5 at first.

This fixes#1682, a recent regression that came out of
a5a47e13fc9d, which introduced the update_rendered_messages()
function in compose_fade.js. The original implementation
was finding the table row for a message, but not the table
row for its recipient bar. Now we style both elements.
(imported from commit a9628df0b03f79a24dfa68f4f2061eda2ca8ecea)
The call to compose_fade.update_faded_messages() in message_list
caused us to traverse every message in the current table, which
was extremely inefficient. Now we call the newly created
compose_fade.update_rendered_messages(), which only fades/unfades the
messages passed in as the first parameter.
(imported from commit a5a47e13fc9daeedd0899b2cfb02beb3f6b8cd0a)
We instead implemented the ~desired functionality here using the
API and a bot to make a totally read-only, static, slowly-updating
view into the Zuliverse.
This is the moral equivalent of reverting deb035b4c702fcdb0e660ed549fe74c682abb6d9

1) The class Filter now lives in its own module.
2) The function canonicalized_operators() is now a class method on Filter.
3) The function message_in_home moved to filter.js and became private.
4) Various calling code had to change, of course.
5) Splitting out Filter helped simplify a few tests.

The compose_fade has three public exports:
set_focused_recipient
unfade_messages
update_faded_messages
All code was pulled directly from compose.js, except for the
one-line setter of set_focused_recipient. The focused_recipients
variable that used to be in compose.js was moved to compose_fade.js,
hence the need for the setter.

"Kiosk mode" is a "read-only" Zulip suitable for embedding into
an iframe on another site. I say "read-only" in quotation marks,
because the account is still a fully-fledged active account on
the server, and we just tear out a bunch of stuff in Javascript
(that a malicious user could easily re-enable).
So in that sense, it's not actually safe in security-sensitive
environments -- malicious users logged in via kiosk mode
can do anything the kiosk-mode user can do.
(We need this functionality for the customer3 realm specifically;
we'll possibly just tear this code back out once that experiment
has run its course.)

This is a pure refactoring that mostly just moves code from
subs.js to the new stream_color.js and updates module references
accordingly. In order to prevent introducing some exports,
update_stream_color was given an additional "sub" parameter
and update_stream_sidebar_swatch_color was given an "id"
parameter.
Killed off unused initial_color_fetch var.

Summarized messages are not shown and cannot be selected. If
`opts.use_closest === false` and you try to select a summarized
message, we still have to use the closest instead of failing.
Eventually, we'll make summary rows selectable, but that would be
rather involved since selections are managed by ID, summaries exist only
in the DOM, and many parts of the code get the selection and expect
it to be a message.

When you read messages in a narrow and then un-narrow, collapse
adjacent messages read in the narrow into a summary row that can
be clicked to expand those messages.
Scoped to staging with feature flags.
The implementation of this within our current MessageList is rather ugly.

In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.
Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.
Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).
One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
