* generic/tclUtil.c: Updated Tcl_GetNameOfExecutable() to

        * generic/tclEncoding.c:        make use of a ProcessGlobalValue for
        * generic/tclEvent.c:           storing the executable name.
        Added internal routines Tcl(Get|Set)ObjNameOfExecutable() to access
        that storage in Tcl_Obj, rather than string format.

        * unix/tclUnixFile.c:   Rewrote TclpFindExecutable() to use
        * win/tclWinFile.c:     TclSetObjNameOfExecutable to store the
        executable name it computes.

        * generic/tclInt.h:     Added internal stub entries for
        * generic/tclInt.decls: TclpFindExecutable and
        Tcl(Get|Set)ObjNameOfExecutable.

        * generic/tclIntDecls.h:        make genstubs
        * generic/tclStubInit.c:

        * generic/tclCmdIL.c:   Retrieve executable name in Tcl_Obj form
        * win/tclWinPipe.c:     instead of string form.

        * unix/tclUnixTest.c:   Update [testfindexecutable] command to use
        new internal interfaces.
