also be used in later commits.

- Make the experiments API a static API
- Make all functions except essential ones internal
- Refactor accordingly

This is not a breaking change: this function originally landed in the
development of 0.48.0 and this new commit should be released in the same
version.

* Closes #2291
* Closes #1830

Without this it's harder to know who to contact for questions.

Issue #1499: Gradle wrapper: Use Gradle distribution with sources (to get API documentation in IDE).

This lets TalkBack users know how many results there are for a certain
string as they type without having to move a11y focus to the results
label.

This is important for TalkBack. When the caret in Gecko moves from a
focusable element (like a link) to a non-focusable element (like a text
node in a P), the link is blurred and the document gets focus.

TalkBack then moves the accessibility focus to the input focus, and this
throws the user off of the search result.

With release of appservices' 0.20.2, repository mirroring is no longer used.
This means we need to declare dependency on the custom repository where it's
currently published. We do this via a shared plugin, so that this dependency
management is easier down the road.
