request_to_sip: break out part of this function to new function determine_sip_location. determine_sip_location: sipurl:parse_url_with_default_protocol returns 'error', not 'none' - found using Dialyzer. determine_sip_location: change result code when no ENUM and no sipproxy from 503 to 480 - it is a better choice with no known side effects. Make result code configurable using 'pstnproxy_no_sip_destination_code'.
