* generic/tclStubInit.c: regen

	* generic/tclIntPlatDecls.h: regen
	* generic/tclInt.decls: added TclWinResetInterface

	* win/tclWin32Dll.c (TclWinResetInterfaces):
	* win/tclWinInit.c (TclpSetInitialEncodings, WinEncodingsCleanup):
	add exit handler that resets the encoding information to a state
	where we can reuse Tcl.  Following these changes, it is possible
	to reuse Tcl (following Tcl_FindExecutable or Tcl_CreateInterp)
	following a Tcl_Finalize.
