Addressable::URI interprets the `#` in a URI as a URI fragment
and does not escape it, but Rails has special helpers that treats
these as bona-fide characters that need to be escaped.

`Rugged::Reference.valid_name?` used in
`Gitlab::GitRefValidator.validate` fails on strings containing null
bytes because it uses `StringValueCStr()`. Per
https://silverhammermba.github.io/emberb/c/:

Ruby’s String kinda corresponds to C’s char*. The simplest macro is
StringValueCStr() which returns a null-terminated char* for a
String. The problem here is that a Ruby String might contain nulls - in
which case StringValueCStr() will raise an ArgumentError!

Override CI_COMMIT_REF_SLUG for QA branches

See merge request gitlab-org/gitlab-ce!23346

Use shelling out to git to write refs instead of rugged, hoping to
avoid creating invalid refs.

To update HEAD we switched to using `git symbolic-ref`.

It's more semantically accurate for what we're verifying.

Previously, we wasted time creating a maintainer and signing them in,
then loaded the entire commit list just to verify the GPG status of a
single commit.

Now, we rely on the project being public so no user needs to be
authenticated, and load just the page for the commit we care about.

We're trying to give the arbitrary SHAs required by each spec a
meaningful name.

This also adds an explicit `ref` definition to each spec so we're not
dealing with a mystery guest.

Previously, this group of specs would create a new user, add them as a
maintainer, sign them in, load the project's commit list, click a
specific GPG key badge, and then verify the content in the popover.

Now, we make the project public in order to skip the user setup and
login, and load a specific commit page because it loads faster than the
commit list while still showing the GPG badge.

CE port of "Move merge request approval settings"

See merge request gitlab-org/gitlab-ce!23157

The `gitlab:assets:compile` job isn't run for the QA branches, thus
there's no Docker image correspinding these branches in the registry.

By overriding `CI_COMMIT_REF_SLUG` to `master` for QA branches, the
`fetch-assets` job in the `omnibus-gitlab` pipeline will pull the
`master` assets Docker image.

Some older browsers do not ship with isIntersecting, while they already
have IntersectionObserver support. We make use of `intersectionRatio`
now to fix the Lazy Loader for those browsers.
