Mutter (and libmutter users) are the only users of this version of cogl, and will more or less only use the cogl-1.0, cogl-2.0 and cogl experimental API variants, and having the possibility of having different API versions of the same API depending on what file includes it is error prone and confusing. Lets just remove the possibility of having different versions of the same API. https://bugzilla.gnome.org/show_bug.cgi?id=768977
