Removed functions marked deprecated or obsolete for a long time: Tcl_Backslash, Tcl_EvalFile, Tcl_GlobalEvalObj, Tcl_GlobalEval, Tcl_EvalTokens.
Remove Tcl_FindExecutable from stub table: It is needed by embedders, not extenders.
Remove TclpGetDate, TclpGmtime, TclpLocaltime: it isn't use anywhere since the new clock implementation.
Remove TclWinConvertWSAError, it's the same as TclWinConvertError.
