Initial commit of new Canvas operation recording / replay

Done:
- drawRect, drawBitmap, drawColor, drawPaint, drawRenderNode, drawRegion
- Recording with new DisplayList format
- batching & reordering
- Stateless op reorder
- Stateless op rendering
- Frame lifecycle (clear, geterror, cleanup)

Not done:
- SaveLayer (clipped and unclipped)
- HW layers
- Complex clipping
- Ripple projection
- Z reordering
- Z shadows
- onDefer prefetching (text + task kickoff)
- round rect clip
- linear allocation for std collections
- AssetAtlas support
