major clean-up pass over unwinding/module-info abstraction, + usage in the debug engine. simplified / cleaned up DWARF helpers for unwind info & expressions. decoupling unwinding / DWARF evaluation from memory read callbacks. light module info now prepared by demon layer - debug engine no longer duplicates per-backend parsing. unwind abstraction layer now does thin abstraction over unwinding backends, debug engine only calls abstraction. clean up demon to have fewer ad-hoc 'queries' on handles, and prefer sending info over debug events when possible / when it fits the usage pattern. move DWARF enum specifications to metacode, generate enums/xlists/tables/etc. decouple raddbg/radbin completely from old parsing helpers. replace portion of DWARF dumping; pull out some new parsing helpers from converter / dumper.
