It's broken by design. There can be multiple DisplayChangeListener
instances, so they simply can't store state in the (single) DisplayState
struct. Try 'qemu -display gtk -vnc :0', watch it crash & burn.
With DisplayChangeListenerOps having a more sane interface now we can
simply use the DisplayChangeListener pointer to get access to our
private data instead.

Split callbacks into separate Ops struct. Pass DisplayChangeListener
pointer as first argument to all callbacks. Uninline a bunch of
display functions and move them from console.h to console.c

This patch adds 'vc' support to qapi and also switches over the
vc chardev initialization to the new qapi code path.

This is minimalistic and just contains the basic widget infrastructure. The GUI
consists of a menu and a GtkNotebook. To start with, the notebook has its tabs
hidden which provides a UI that looks very similar to SDL with the exception of
the menu bar.
The menu bar allows a user to toggle the visibility of the tabs. Cairo is used
for rendering.
I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU
since it was originally written as a remote display for QEMU. So for the most
part, the approach to rendering and keyboard handling should be pretty solid for
GTK.

We want to expose VCs using a VteTerminal widget. We need access to provide our
own CharDriverState in order to do this.

In case host and guest endianness differ the vga code first creates
a shared surface (using qemu_create_displaysurface_from), then goes
patch the surface format to indicate that the bytes must be swapped.
The switch to pixman broke that hack as the format patching isn't
propagated into the pixman image, so ui code using the pixman image
directly (such as vnc) uses the wrong format.
Fix that by adding a byteswap parameter to
qemu_create_displaysurface_from, so we'll use the correct format
when creating the surface (and the pixman image) and don't have
to patch the format afterwards.
