Steve Howell 110c15737f Rename filter.callback to filter.predicate. 
The filter "callback" was only a "callback" in the
most general sense of the word.

It's just a filter predicate that returns a bool.

This is to prepare for another filtering option,
where the caller can filter the whole list
themselves.  I haven't figured out what I will name
the new option yet, but I know I want to make the
two options have specific names.

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.

Rohitt Vashishtha c41c82aae0 settings_emoji: Use display_name in handlebars. 
This commit fixes two issues with the previous implementation:

1. JavaScript's replace replaces only the first instance,
   thus we need to use a regex.
2. Handlebars was setting the id of the HTML elements with
   spaces in between which broke the delete button; now a
   new variable display_name is passed to the template.

This also makes changes to the casper tests to have an emoji
name with multiple spaces in it to ensure this bug doesn't
appear again.

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.

Shubham Dhama eb0da20b78 settings: Clean up repeating code in error callbacks. 
This cleans repeating code in error callback in settings.
We made a generic function in `ui_report.js` which require two
arguments `xhr` and `btn`; we preferred `btn` over `row` as argument
because a row may have more than one buttons.

Fixes: #8788.

Steve Howell aac76c14bd settings: Avoid duplicate form handlers. 
For forms that are built early in setting up the settings panel,
we don't want to attach multiple submit handlers every time we
go into the gear menu, so we use "off" to clear any old handlers.

We also attach handlers directly to the form, instead of
using delegation up to the container div.
