This modifies the common virtio-gpu.h file have the fields and
defintions needed by gfxstream/rutabaga. It also modifies VirtioGPUGL
to have the runtime options needed by rutabaga. They are:
- a colon separated list of capset names, defined in the virtio spec
- a wayland socket path to enable guest Wayland passthrough
The command to run these would be:
-device virtio-vga-gl,capset_names=gfxstream:cross-domain, \
wayland_socket_path=/run/user/1000/wayland-0,hostmem=8G \
It will be nice if it automatically determines the socket path according to:
https://wayland.freedesktop.org/docs/html/apb.html#Client-classwl__display_1af048371dfef7577bd39a3c04b78d0374
A documentation to set up cross-domain just like what you can find in
the crosvm book* will also be helpful.

I prefer to have a line:
struct rutabaga;
In virtio-gpu.h and use it here. Perhaps it may be a bit weird to have
such a declaration in a renderer-independent file, but it's practically
harmless, can prevent something rouge from being assigned to the member,
and allows to use the variable without annoying casts.
