* models/record.go: SRV targets are case insensitive. Downcase them. * models/t_srv.go: Rename setTargetIntAndStrings() to setTargetSRVIntAndStrings() (makes it easier to search for /setTargetSRV/). * pkg/js/parse_tests/021-srv.js*: SRV: Add parse_tests * pkg/normalize/validate.go: SRV targets are hostnames, turn into FQDNs. * Add #rtype_variations warnings for future developers
