Add class id to debugger stack trace

Add class id to debugger stack trace

Add the class id of the origin class of each activation frame’s function.
Top-level functions have no class id. The wire protocol for an activation
frame now looks like this:

CallFrame =	“{“ functionName “:” String “,”
                    [ location “:” Location “,” ]
                    [ classId “:” Integer “,” ]
                    locals “:” NamedObjList “}“
