All this does is convert the version sections into headers. The list
items shouldn't really be indented by two spaces, but it makes no
difference to the rendering and this way we retain authorship history
for the actual changes.

Closes #23239

Using `extend self` prevents GitLab Performance Monitoring from being
able to track class methods.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/23347

As discussed in https://gitlab.com/gitlab-org/gitlab_git/issues/28 we'll
need to clearly document the need for .gitattributes files being encoded
using UTF-8.

available under a new /templates namespace. Old endpoints will be
deprecated when GitLab 9.0.0 is released.

We need to do two things to support this:

1. Simplify the regex capture in the routing for the CommitsController
   to not exclude the '.atom' suffix. That's a perfectly valid git
   branch name, so we shouldn't blow up if we get it.
2. Because Rails now can't automatically detect the request format, add
   some code to do so in `ExtractPath` when there is no path. This means
   that, given branches 'foo' and 'foo.atom', the Atom feed for the
   former is unroutable. To fix this: don't do that! Give the branches
   different names!
