Chris Jones 270f8e37db Bug 804852: Support for the hwc implementation of Composer2D. r=mattwoodrow,mwu,roc sr=roc
This is a rollup of the following patches

part 0: Add a dynamic cast to ColorLayer*

part 1: Add a Composer2D interface to enable implementations to more efficiently compose layer trees

part 2: Let widgets expose Composer2Ds, if they have them

part 3: Expose a layers ogl "friend" API that Composer2D will consume

part 4: Hook Composer2D into the LayerManagerOGL rendering pipeline

part 5: Implement all the goop to let widget/gonk use a Composer2D (HwcComposer2D)
