Matthias Clasen 533aaba5eb wayland: Support xx-color-management-v2 
This is a still experimental protocol (thus the xx prefix).

We are using it go obtain information about the compositors
preferred color state, and pass that on to our rendering machinery.

The currently supported color states are srgb, srgb-linear, rec2100-pq
and rec2100-linear. We don't have any support for ICC profiles.

Unlike other protocols, keep the support code for this protocol
fairly isolated behind wrapper objects, since the protocol is
still subject to change.
