This is preparation for the CM&HDR protocol implementation. It requires us to give a unique id to each color-profile, so let's do that. In this commit we introduce a generic id generator to libweston, and its first user: the color-profile. Signed-off-by: Leandro Ribeiro <leandro.ribeiro@collabora.com>
