When project is updated and it is a fork, then visibility_level
should not be less restrictive than in its parent project.

Extend yml syntax for only and except to support specifying repository path

This allows to limit execution of jobs to specific repository.

For example:
```yaml
job:
  only:
    - branches@gitlab-org/gitlab-ce
  except:
    - master@gitlab-org/gitlab-ce
```

The above will run `job` for all branches on `gitlab-org/gitlab-ce`, except master.

@dzaporozhets @JobV @vsizov Please review.

Update links in CI docs after GitLab 8.1

Fix that some links to CI status in docs were broken even after following redirects.

As CI build overview is now missing (cf. #3008), this MR uses `?scope=all` parameter.

Reduce disk IO and space usage during backups

This is based on improvements made to the GitLab CI 8.0 backup script.

- Avoid creating many small intermediate files while backing up builds and uploads by using tar and light gzip compression
- Use same backup/restore code for uploads and builds
- Only store a compressed intermediate DB dump

See merge request !1520

Add custom protocol whitelisting to SanitizationFilter

Addresses internal https://dev.gitlab.org/gitlab/gitlabhq/issues/2613

We allow any protocol for autolinks: irc://irc.freenode.net/git

But manual Markdown links with the same protocol get sanitized: `[This will not be clickable](irc://irc.freenode.net/git)`: [This will not be clickable](irc://irc.freenode.net/git)

To get around this we have to first allow *all* protocols, and then manually clean dangerous (i.e., `javascript:`) protocols.

Persist blob editor's value on submit, not on click

Prior, the value of the Ace editor was only being persisted if the user
physically clicked the submit button, which the "quick submit" behavior
doesn't do.

Now the value will be properly transferred before any form is submitted.
