console: stop using PixelFormat
With this patch the qemu console core stops using PixelFormat and pixman format codes side-by-side, pixman format code is the primary way to specify the DisplaySurface format: * DisplaySurface stops carrying a PixelFormat field. * qemu_create_displaysurface_from() expects a pixman format now. Functions to convert PixelFormat to pixman_format_code_t (and back) exist for those who still use PixelFormat. As PixelFormat allows easy access to masks and shifts it will probably continue to exist. [ xenfb added by Benjamin Herrenschmidt ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
