Anders Kaseorg 6ec808b8df js: Add "use strict" directive to CommonJS files.
ES and TypeScript modules are strict by default and don’t need this
directive.  ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Anders Kaseorg f3726db89a js: Normalize strings to double quotes.
Prettier would do this anyway, but it’s separated out for a more
reviewable diff.  Generated by ESLint.

Steve Howell d4fc28cf42 list_cursor: Avoid tracebacks.
In rare situations we would get tracebacks from
list_cursor on the line that I changed here.  We
went the entire month of May without a traceback
here, and I can't reproduce the problem.

This is a pretty clear fix, though, and it will
hopefully lead to a more enlightening symptom.

The likely scenario here is that you use `q` to
navigate the stream list and then unsubscribe.
I tested that and couldn't get a traceback,
but I do think the traceback indicates some
possible issues.

The behavior I saw when I did this
appeared to be mostly harmless.
When I deleted a row (by unsubscribing), the code
seemed to effectively disable the cursor.  It's
possible we should go to the next row or fully disable
the search.

I opened #15439 to follow up on this and other
cursor-related issues.

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 d17b577d0c js: Purge useless IIFEs.
With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

Steve Howell eb7f7fae55 list_cursor: Promote error handling code.
If a caller passes undefined to go_to, it is
almost certainly a programming error, so we
shouldn't silently ignore it just because
the current key is undefined.

We also avoid setting curr_key until we
validate the incoming key.

Steve Howell 1a84af1e79 buddy list: Add v1 progresive scrolling.
This version of progressive scrolling lazily
renders buddy list items, but it doesn't
provide the browser with any notion of upcoming
list items, so as you scroll down and the size
of the rendered list grows, the scrollbar shows
you being too close to the bottom.

This maintains 100% coverage on buddy_list.js.

Steve Howell 407b13af25 list_cursor: Replace container with scroll_container_sel.
Our lists tend to have both containers and scroll_containers,
and we care more about the latter to the extent they're
different.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
This commit prepares the frontend code to be consumed by webpack.

It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.

However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.

So we expose the modules by setting window.varName = varName; as
needed in the js files.

Steve Howell 97b9367d20 refactor: Extract scroll_util.js.
We now use scroll_element_into_container() in two different
places, so it's worth extracting.

Steve Howell fb712027bf buddy list: Fix and simplify up/down navigation.
This introduces a generic class called list_cursor to handle the
main details of navigating the buddy list and wires it into
activity.js.  It replaces some fairly complicated code that
was coupled to stream_list and used lots of jQuery.

The new code interacts with the buddy_list API instead of jQuery
directly.  It also persists the key across redraws, so we don't
lose our place when a focus ping happens or we type more characters.

Note that we no longer cycle to the top when we hit the bottom, or
vice versa.  Cycling can be kind of an anti-feature when you want to
just lay on the arrow keys until they hit the end.

The changes to stream_list.js here do not affect the left sidebar;
they only remove code that was used for the right sidebar.
