Use the new qemu_pixelformat_from_pixman and qemu_default_pixman_format
functions to reimplement qemu_default_pixelformat
(qemu_different_endianness_pixelformat too).

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.

This patch adds a qemu_create_displaysurface_guestmem helper function.
Works simliar to qemu_create_displaysurface_from, but accepts a
guest address instead of a host pointer and it handles
cpu_physical_memory_{map,unmap} for you.

If we need to, we should use the pixman formats instead but for
now this is unused except in commented out code so take it out
to avoid further confusion about surface endianness.
