This makes a start on clearly factoring the deprecated code of core Cogl into a deprecated/ directory. Ideally we want to get to the point where all code here can be re-worked in terms of the public 2.0 api so that it can be kept indefinitely for cogl 1.x api compatibility without cluttering the core code base itself. If we can do this then we can avoid maintaining the Cogl 1.x branches in parallel with master which would reduce the maintenance effort.
