Profile trace enhancements: - add optional argument "-builtins" to nsf::__profile_trace to trace a selected list of builtins. Every element of the list passed to "-builtins" might contain a cmd name and optionally a maximum number of arguments to be shown (typically 0 or 1) - generalized NsfReplaceCommand* logic to become more general usable (e.g. for the builtins mechanism of nsf::__profile_trace)
- Use standard logging for nsf::__profile_trace ... -verbose true ... By using the standard logging mechanism, we can redefining ::nsf::log to output e.g. trace in a GUI. - Add argument "-dontsave" to nsf::__profile_trace to avoid saving trace in memory - Refactor trace and debug output to deliver lists. This makes it easier to postprocess the results from Tcl.
