Use gitlab-git-http-server 0.3.0 for GitLab 8.1

See merge request !1605

This adds indexes for the following columns:

* notes.line_code
* ci_projects.gitlab_id
* ci_projects.shared_runners_enabled
* ci_builds.type
* ci_builds.status

Track compatible gitlab-git-http-server version

The 'git archive' changes in GitLab 8.1 require a version of
gitlab-git-http-server that is incompatible with GitLab 8.0, so we
need to keep track of this now.

Add a system note and update relevant merge requests when a branch is deleted or re-added

If a branch is deleted with an open merge request, amended offline, and then pushed again,
GitLab doesn't bother to update the merge request even though the last commit ID and/or
code may have changed. This MR ensures that each push will update any relevant merge
requests and adds a system note if this happens as well.

The new messages look like:
