Yuri Kunde Schlesner e321decf98 Remove SyncRequest from K::Object and create a new K::Session type
This is a first step at fixing the conceptual insanity that is our
handling of service and IPC calls. For now, interfaces still directly
derived from Session because we don't have the infrastructure to do it
properly. (That is, Processes and scheduling them.)
