weston_renderer::repaint_output must be called from the weston_output::repaint
callback. When called from the weston_output::enable callback, a black frame
is produced. Instead of painting an invalid buffer and then working around it
by setting output damage, just don't skip the first real repaint even though
no VNC client is connected yet.

Since neatvnc frame buffers are in system memory, using a shadow
buffer just causes an unnecessary copy in the pixman renderer.
Stop using the shadow buffer.

It is enough to report new repaint damage instead of accumulated

While not repainting, all buffers are damaged exactly the same.
Avoid unnecessary work by tracking this damage separately on struct
vnc_output.

Push weston_coord into the notification functions instead of passing
two doubles.
The touch handlers are passed a pointer to a weston_coord, which is
unusual. This is done so we can pass a NULL pointer instead of a
fabricated invalid coordinate when the touch type is TOUCH_UP.

This creates a global coordinate from a device coordinate.
Replace it with weston_coord_global_from_output_point() which
does the same thing and returns a weston_coord_global.

Add a create_image_from_ptr vfunc to struct pixman_renderer_interface,
which wraps weston_renderbuffer creation for the pixman renderer via

To avoid retrieving the backend from the compositor all the time, store
a pointer to the vnc backend on its vnc_output structures.
This will be useful once the compositor contains more than one backend.

Passing the backend as a parameter to the weston_backend function
pointers seems more natural and will be very useful once there can be
more than one backend.
Since all backends already store a pointer to the compositor instance,
replace the compositor parameter with the backend in all functions.

When the output is moved, move its per-framebuffer accumulated damage
with it. The alternative would be to track accumulated damage in the

into global coordinates for repaint_output.

Compositor code can use opaque pointer comparison to determine whether
a head belongs to a given backend. Store a backend pointer in struct
weston_head to enable the compositor to select the correct backend
specific output configuration code.
This also allows to use the backend pointer instead of the opaque
backend_id pointer to check whether a head belongs to a backend, so
replace the checks in all to_xyz_head() functions and drop backend_id.

This adds basic VNC protocol support using the Neat VNC library
(https://github.com/any1/neatvnc). Neat VNC depends on the AML main
loop library. The backend makes use of AML's integrated epoll backend
and connects AML via file descriptor with the Wayland event loop.
This implementation does not support authentication and hardcodes the
pixel format currently.
