File 0053-gtk-Add-handling-for-the-xfree86-ke.patch of Package qemu.4227

Subject: [PATCH] gtk: Add handling for the xfree86 keycodes

Currently only evdev keycodes are handled by the gtk-ui. SDL has
code to handle both. This patch adds similar processing so that
both keycode types will be handled via the gtk-ui.
