This change introduces an unread_topic_counter object
that manages unread counts for streams and topics. Consolidating
all the logic into a single class will set us up to add
logic for dealing with topic counts that includes provisional
counts of unread messages from the server. It also makes
the current code a little easier to reason about.
Most of this change was simply extracting functions, but
I also removed a few unnecessary and inconsistent calls to
`stream_data.canonicalized_name` that preceded our use of
Dict with a fold_case argument.
We now use comma-delimited lists of user_ids for the following
data structures in unread.js:
- unread_privates[<user_ids_string>]
- get_counts.pm_count[<user_ids_string>]
It's been very buggy for a while, has limited usefulness compared with
unread counts, and profiling over the weekend indicates that it's very
slow.

I could not find where we were setting the read flag on messages in
response to a update_message_flags event. This fixes a bug where a
user's read position will not be correctly synced in muted streams. For
muted streams the cursor updates seem to force the client to mark the
messages as read.

This experiment has been disabled for everyone for a while: if we
bring something like this back, it is not likely to be exactly the same,
and will be different enough to require a different implementation.
As it is, the summarization code was making a few code paths (rendering
especially) more complex, and is worth removing for simplicity's sake.

There is a scenario where we call process_read_message()
for a message that we haven't recorded as unread before.
I'm not sure how it happens, but I put back code to
guard against crashing. The regression happened in
5752458c821.

Update get_counts() so that it ignores counts for muted topics
when calculating stream/home unread counts.

The indirection was more confusing than helpful, especially
since the function had side effects, despite its getter-like
name.

After killing off unread_counts.stream, the only field of
unread_counts was "private", so I just made unread_privates.

The prior commit makes it so that we no longer use unread_counts.stream
in get_counts(). This commit removes the code that updates the
data structure.

These two data structures are kind of redundant:
unread_counts['stream']
unread_subjects
We are deprecating the former. The latter is more flexible for
features like muting.
Now, in get_counts(), we compute home counts and stream counts
in the same loop that computes subject counts.

The setdefault() and num_items() methods are handy, and it was a
little tough to keep track of which objects were Dicts vs. {}.

Have ui.set_presence_list() only touch the presence list.
Before this change, it was calling update_unread_counts(), which
has a bunch of side effects unrelated to the presence list.

We had a duplicate and incorrect check on if a stream was in your home
view, which caused us to not display Home unread counts in the sidebar
/ notification bar / Dock on page load.

There are also one or two places we don't need to use it for security
purposes, but we do so for consistencey.

This covers most of the module's functionality, with special
emphasis on lines that use underscore.js (_.each and _.filter).
