The main motivation behind the split is to simplify client buffer code and allow adding new features easier, for example referencing the shm pool when a shm buffer is destroyed, or monitoring for readable linux dmabuf file descriptors, etc. Also, a referenced ClientBuffer cannot be destroyed, unlike the old BufferInterface.
