* generic/tclCmdMZ.c (Tcl_TraceObjCmd, TraceVarProc)
(TraceCommandProc, TclTraceCommandObjCmd): corrected
potential double-free of traces on variables by flagging in
Trace*Proc that it will free the var in case the eval wants to
delete the var trace as well. [Bug #536937]
Also converted Tcl_UntraceVar -> Tcl_UntraceVar2 and Tcl_Eval to
Tcl_EvalEx in Trace*Proc for slight efficiency improvement.
