When the output is moved, move its per-framebuffer accumulated damage
with it. The alternative would be to track accumulated damage in the
local output coordinate system, but that would require translating back
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.

No output is created at this point. Even if an output existed,
it should be relased when the head ist destroyed.

vnc_ensure_matching_mode() does not transfer flags from init_mode.
Set flags on the returned mode instead.

Let xzalloc warn and abort when running out of memory.
With this, vnc_insert_new_mode() and vnc_ensure_matching_mode() can not
return NULL anymore. Remove the now unnecessary error handling.

Let VNC clients authenticate using the local username and password of
the user weston is running as. To avoid transmitting the password in
cleartext, make TLS security mandatory.

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.
