Ref and sink priv->tooltips in init() and unref priv->tooltips in destroy

	* gtk/gtkcolorsel.c: Ref and sink priv->tooltips in
	init() and unref priv->tooltips in destroy rather
	than calling gtk_object_destroy() which has no
	effect on memory management. (#66104, HideToshi
	Tajima)
	* gtk/gtkcolorsel.c (palette_set_color): Use g_object_set_data_full()
	so we free the when the object is freed. (Fixes memory
	leak, #66096, HideToshi Tajima)
	* gdk/gdkevents.c (gdk_synthesize_window_state): Use
	a full GdkEvent structure to avoid reads of uninitialized/
	invalid memory in gdk_event_put() (#65877, patch
	from Hidetoshi Tajima)
