Original issue's description:
> CSP: Convert CSPSource constructor bools into a enum.
> 
> Rather than passing the wildcard disposition of CSPSource's hosts and ports
> as booleans, we should have an enum that allows us to figure out hat we
> mean at the callsite. This patch adds CSPSource::WildcardDisposition in
> order to make this clear.
