In this MR we add support to the majority of the interfaces from the
color-management protocol.

That means that we are able to advertise output's images descriptions to
clients, preferred surface images descriptions, and so on. We also
support clients that wants to create ICC-based images descriptions and
set such descriptions for surfaces.

We still don't support the interface to allow clients to create
image descriptions from parameters, but that should be addressed
in the near future.
