Repurpose checklocksalias as a type-level annotation so alias relationships are declared once per type instead of per call. Update tcp/ipv4 annotations accordingly and drop per-call workarounds. Enhance checklocksfail to allow substring matching so that robust tests for checklocksalias are possible.
