* update loki-mq submodule for tuple support * srv record reply implementation still need to encode srv records into intro sets / router contacts as well as decode from them and match against queried service.proto * inverted condition fix in config code * SRV record struct (de-)serialization for intro sets * parsing and using srv records from config (for/in introsets) * adopt str utils from core and use for srv parsing * changes to repeat requests no longer drop repeat requests on the floor, but do not make an *actual* request for them if one is in progress. do not call reply hook for each reply for a request, as each userland request is actually made into several lokinet requests and this would result in duplicate replies. * fetch SRVs from introsets for .loki * make format * dns and srv fixes, srv appears to be working
