* generic/tclInt.decls: Revised the interfaces of the routines

        * generic/tclExecute.c: TclStackAlloc and TclStackFree to make them
        easier for callers to use (or more precisely, harder to misuse).
        TclStackFree now takes a (void *) argument which is the pointer
        intended to be freed.  TclStackFree will panic if that's not actually
        the memory the call will free.  TSA/TSF also now tolerate receiving
        (interp == NULL), in which case they simply fall back to be calls to
        Tcl_Alloc/Tcl_Free.

        * generic/tclIntDecls.h:        make genstubs

        * generic/tclBasic.c:   Updated callers
        * generic/tclCmdAH.c:
        * generic/tclCmdIL.c:
        * generic/tclCompCmds.c:
