Add wx/gtk/private/wrapgtk.h wrapping gtk/gtk.h in pragmas disabling these warnings and include it everywhere instead of directly including gtk/gtk.h. Also include wx/gtk/private/gtk2-compat.h from this wrapper header as it was included by 90% of the files including gtk/gtk.h itself and it seems to be better and simpler to just always include it.
