mod_http_oauth2: Make allowed locales configurable Explicit > Implicit Instead of allowing anything after #, allow only the explicitly configured locales to be used. Default to empty list because using these is not supported yet. This potentially limits the size of the client_id, which is already quite large. Nothing prevents clients from registering a whole client_id per locale, which would not require translation support on this side.
