Steve Howell 0aa9decd86 blueslip: Add feature to time common operations.
This is relatively unobtrusive, and we don't send
anything to the server.

But any user can now enter blueslip.timings in the
console to see a map of how long things take in
milliseconds.  We only record one timing per
event label (i.e. the most recent).

It's pretty easy to test this by just clicking
around.  For 300 users/streams most things are
fast except for:

    - initialize_everything
    - manage streams (render_subscriptions)

Both do lots of nontrivial work, although
"manage streams" is a bit surprising, since
we're only measuring how long to build the
HTML from the templates (whereas the real
time is probably browser rendering costs).

Steve Howell 631811e686 streams: Add BinaryDict for stream_data.
This should make any operation on subscribed
streams faster (we won't need to filter out
unsubscribed streams every time).

I started writing this before I realized we
had a bug where we call `subscribed_streams`
in a nested loop.

After fixing the bugs, this is not as much of
a bottleneck, but it's still a speedup in many
important places:

    * build left sidebar
    * every keystroke in search bar
    * first keystroke in making #stream_links
    * every keystroke in compose stream box

The streams settings code is kinda complicated.
It does a non-deterministic sort of the "others"
bucket when you add elements to the left panel.
They get hidden, anyway.  Our values() call now
puts subscribed streams first.  It never guaranteed
order, but putting subscribed streams first is
probably a good behavior for most situations.

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Anders Kaseorg 141088586b Completely replace perfect-scrollbar with SimpleBar.
perfect-scrollbar replaces both the appearance and the behavior of the
scrollbar, and its emulated behavior will never feel native on most
platforms.  SimpleBar customizes the appearance while preserving the
native behavior.

Steve Howell 82e453d9fe ui: Fix scrollbar regressions.
In between releases, the following commit introduced
a bug where we agressively scroll to the top every
place we call `ui.update_scrollbar`:

    092b73d0b7

The main symptoms were that the left and right sidebars
would go to the top for things like selecting a topic,
getting activity updates from the server, and resizing
the window.  It was very jarring.

The recent commit looked innocuous--the root of the problem
was the original API expressed an intent to scroll to the
top, but didn't actually do it, so it was a bug in hiding.

There are **some** occasions where it's actually appropriate
to scroll to the top, mostly around search filtering, and
in those places we now call the new `ui.reset_scrollbar`
function.

This is a bit of an emergency fix, so particularly with
the settings stuff, we may get more reports of glitches here.

The important thing here is that you almost never want to
reset the scrollTop for sidebars.

Steve Howell a7d7f6cada settings: Make unsubscribed streams less sticky.
When you unsubscribe a stream by clicking on the
checkmark, we don't want it to disappear right
away, but we also don't need it to stay around
once you start searching for new streams.

Note from Tim: This commit removes some complex code that was just a
workaround for the fact that this widget used to automatically
re-filter immediately after clicking to unsubscribe a user.

Since we've since fixed that original issue, we don't need this.

Steve Howell f63dde8777 node tests: Add coverage to subs.js.

its values to simulate data for filter_table().

Steve Howell 95d136ca5e Extract search_util.js module.
We probably should have done this a while ago, even
though these functions are pretty tiny.  The goal here
is to make it easier to have more consistent search
semantics.

Our first use case is subs.js.  In this case we
are able to decouple a bit of generic string
matching from the subs-specific code.

Steve Howell 064d0f3c89 Extract stream_data.sort_for_stream_settings().
We move some data code from subs.js to stream_data.js.

It's not clear we have been using the optimal sort for
dealing with locales, but this change preserves the
current behavior.  The only subtle change here is that
we look up subs using a Dict now instead of a plain
JS object.

Steve Howell 5641c77c94 refactor: Introduce other_stream_ids in filter_table().

Tim Abbott c8db7b7dd7 node: Provide a default window object for the node tests.
This is preparation for our migration of our JS pipeline to webpack,
which includes as part of the process a hack of exporting globals via
the window object.

Steve Howell 42435db492 Add run_test helper for individual tests.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests.  (The latter goal has some
complications, since we often intentionally leak
setup in tests.)

vaibhav 35c1272525 Include stream description matches in filter results.
User search for streams will now return results where the stream
description (but not the stream name) include the string in the
user query.

The filtering process first obtains the streams whose names match the
user search query, then sorts and displays them. From the remaining
streams, it obtains streams whose description matches the query and
displays them in sorted order after the name match results. Other
streams are not displayed.

Fixes: #2674.

khantaalaman c3fd0d4e0c subs: Fix incorrect use of RegExp in stream filtering.
When filtering streams, we were incorrectly treating the regexp input
provided by the user as a regular expression, meaning that terms like
`c++` would trigger errors because they are invalid regular expression
syntax.  We fix this by replacing RegExp with a simple IndexOf check.

Node test added by tabbott.

Fixes #3559.
