On Firefox 56 and Waterfox Classic, our `runLockdown.js` script throws
an error. This is fine on the HTML pages, as the next script tags still
get run without issue (though they don't benefit from the SES lockdown
sadly). But in the `contentscript`, an exception thrown here appears to
halt the execution of subsequent scripts.
To prevent the `contentscript` from crashing completely, lockdown
errors are now caught and logged. They are also logged to Sentry on the
pages where Sentry is setup.
The metrics e2e test would fail if the segment events still weren't
dispatched when the page loaded. The Segment events are sent on a set
interval, so it isn't abnormal for them to lag behind the page load
itself. The `waitUntilCalled` utility has been used to wait until all
required events have been dispatched.
The `wait-until-called` module was converted to an ES5 module, so that
it could be used from an e2e test. The optional `callCount` parameter
has also been added, to allow waiting for more than one call.
The `segmentSpy` had to be converted to a `segmentStub`, to allow the
`waitUntilCalled` utility to be used.

The change to the way that `punycode` is imported is to address the fact that
third-party module is hidden by the built-in. This is a silly hack but it works.
`@metamask/eslint-config` has been updated to v4.1.0. This update
requires that we update `eslint` to v7 as well, which in turn requires
updating most `eslint`-related packages.
Most notably, `babel-eslint` was replaced with `@babel/eslint-parser`,
and `babel-eslint-plugin` was replaced by `@babel/eslint-plugin`. This
required renaming all the `babel/*` rules to `@babel/*`.
Most new or updated rules that resulted in lint errors have been
temporarily disabled. They will be fixed and re-enabled in subsequent
PRs.
Instead of using `eslint-plugin-json` for linting JSON files,
`prettier` is now used. `prettier` is capable of detecting and
correcting more problems than `eslint-plugin-json` can, such as
indentation.
All JSON files have been run through `prettier`. The changes are all
superficial.
This change updates the shared ESLint config to the latest published version,
v3.1.0.
From the config [`CHANGELOG.md`][1]: v3.0.1 has disabled `prefer-object-spread`
by default, so it has been enabled for this project.

Note that the migrations still use CommonJS require, so the default export as
an object is quite ergonomic (& I don't want to touch the migrations).
Previously all browser globals were allowed to be used anywhere by
ESLint because we had set the `env` property to `browser` in the ESLint
config. This has made it easy to accidentally use browser globals
(e.g. #8338), so it has been removed. Instead we now have a short list
of allowed globals.
All browser globals are now accessed as properties on `window`.
Unfortunately this change resulted in a few different confusing unit
test errors, as some of our unit tests setup assumed that a particular
global would be used via `window` or `global`. In particular,
`window.fetch` didn't work correctly because it wasn't patched by the
AbortController polyfill (only `global.fetch` was being patched).
The `jsdom-global` package we were using complicated matters by setting
all of the JSDOM `window` properties directly on `global`, overwriting
the `AbortController` for example.
The `helpers.js` test setup module has been simplified somewhat by
removing `jsdom-global` and constructing the JSDOM instance manually.
The JSDOM window is set on `window`, and a few properties are set on
`global` as well as needed by various dependencies. `node-fetch` and
the AbortController polyfill/patch now work as expected as well,
though `fetch` is only available on `window` now.
* Use @metamask/eslint-config@1.1.0
