Rework the interaction between the Cogl and GDK / X11 backends. Previously, the Cogl backend was at times a subclass of the X11 backend, and at times a standalone one. Now it is the other way round, with GDK and X11 backends providing the concrete classes, layered on top of the generic Cogl backend. A new EglNative backend was introduced for direct to framebuffer rendering. This greatly simplifies the API design (at the expense of some casts needed) and reduces the amount of #ifdefs, without duplicating code. https://bugzilla.gnome.org/show_bug.cgi?id=657434

Implement multi-backend support The Clutter backend split is opaque enough that should allow us to just build all possible backends inside the same shared object, and select the wanted backend at initialization time. This requires some work in the build system, as well as the initialization code, to remove duplicate functions that might cause conflicts at build and link time. We also need to defer all the checks of the internal state of the platform-specific API to run-time type checks.
