cmd resolver work - fix test, when OS specific cmd resolver is used from a NSF_CSC_CALL_IS_COMPILE frame - improved output from __db_show_obj: put results into one line instead of multiple lines - new debug function __db_get_obj: return into about a tcl_obj in form of a dict (in general, one should not rely on Tcl_Obj internals, especially when upgrading over major Tcl versions, but for testing/understanding behavior etc., such a command is helpful). - extend regression test
