SWW_WAF_ADD_LOOKUP_HEADERS now defaults to true, so the app gets
X-Client-ASN and X-Client-Country with no setting. While
SWW_WAF_LOOKUP_SOURCE is off it defaults to false, so turning lookups
off alone still starts; true set with the lookup off still stops the
start. With GeoJS, a new client's first request now waits for its
answer, up to SWW_WAF_ASN_AND_COUNTRY_LOOKUP_TIMEOUT_MS.
