* generic/tclStubInit.c: Regenerated the stubs support code from

	* generic/tclDecls.h:    the modified tcl.decls (TIP #233, see below).

	* doc/GetTime.3:       Implemented TIP #233, i.e. the
	* generic/tcl.decls:   'Virtualization of Tcl's Sense of Time'.
	* generic/tcl.h:       Declared, implemented, and documented the
	* generic/tclInt.h:    specified new API functions. Moved the
	* unix/tclUnixEvent.c: native (OS) access to time information
	* unix/tclUnixNotfy.c: into standard handler functions. Inserted
	* unix/tclUnixTime.c:  hooks calling on the handlers where native
	* win/tclWinNotify.c:  access was done before, and where scaling
	* win/tclWinTime.c:    between domains (real/virtual) is required.
