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.

// Important note on these tests:
//
// The way the Zulip hotkey tests work is as follows. First, we set
// up various contexts by monkey-patching the various hotkeys exports
// functions (like overlays.settings_open). Within that context, to
// test whether a given key (e.g. `x`) results in a specific function
// (e.g. `ui.foo()`), we fail to import any modules other than
// hotkey.js so that accessing them will result in a ReferenceError.
//
// Then we create a stub `ui.foo`, and call the hotkey function. If
// it calls any external module other than `ui.foo`, it'll crash.
// Future work includes making sure it actually does call `ui.foo()`.
