Gracefully handle errors in syntax highlighting by leaving the block unformatted

A bug in Rouge caused an Exception:

```undefined method `sub' for :Literal:Symbol```

That caused https://gitlab.com/embeddable-common-lisp/ecl/issues/156 to hit Error 500 and fail to display. If a failure occurs, just render the text as preformatted.

Closes #2433

Fix highlighting of deleted lines in diffs.

Resolves internal https://dev.gitlab.org/gitlab/gitlabhq/issues/2498

Only needed until https://github.com/jneen/rouge/pull/297 is merged into
Rouge and the gem is updated in GitLab.

Forking `rouge`, releasing `gitlab-rouge` and using that gem wasn't an
option, since `gollum-lib` has `rouge` as a dependency, so it would get
included anyway, and which code we'd get would depend on the load order.

Fix emoji URLs in Markdown when relative_url_root is used

Path/URL helpers (e.g. `asset_url_helper`) already include the relative_url_root, so there is no need to attach it twice.

Also adds the ability to run rspecs with relative_url_defined on the enviornment. For example:

RELATIVE_URL_ROOT=/gitlab rspec

Do not let NGINX buffer Git HTTP requests

Before this change NGINX would convert a chunked HTTP POST (e.g.
git push) into a HTTP 1.0 single large POST. This creates an
unnecessary delay, and it creates unnecessary memory pressure on
gitlab-git-http-server.

For the response ('proxy_buffering') I am less sure that NGINX 's
buffering behavior is harmful, but it still makes more sense to me
not to interfere with gitlab-git-http-server (and the Golang net/http
server).

Add meta tag for referrer

https://gitlab.zendesk.com/agent/tickets/7054

Added a meta referrer tag, so that only the origin is sent to third party sites, instead of the entire URL, thus avoiding the leak of sensitive information like password reset tokens.
