Implement support for synchronous subsurfaces commits. This means that the client can, by calling wl_subsurface.set_sync, cause its surface state to be commited not until its parent commits. This will mean there will be will potentially be one more surface state (regions, buffer) at the same time: the active surface state, the mutable pending surface state, and the immutable surface state that was pending on last surface commit.
