* macosx/tkMacOSXInit.c:

	* macosx/tkMacOSXNotify.c: introduction of new tcl notifier based on
	CFRunLoop allows replacement of the custom TkAqua notifier by a
	standard tcl event source. Removes requirement of threaded tcl core
	for TkAqua, allows to stub-link TkAqua against Tcl by removing use of
	the unstubbed TclInitNotifier & TclFinalizeNotifier. [Tcl Patch 1202052]

	* macosx/Wish.pbproj/project.pbxproj: stub-link TkAqua: build with
	USE_TCL_STUBS and link against libtclstub instead of Tcl.framework,
	unexport libtclstub symbols from Tk to avoid duplicate symbol warnings
	when linking with both Tcl and Tk, fixes for gcc4.0 warnings.
