The frontend exposes an API to the driver to send invalidations, handles sequence number assignment, synchronization (fences), and provides a timeout mechanism. The backend issues the actual invalidation to the hardware (or firmware). The new layering easily allows issuing TLB invalidations to different hardware or firmware interfaces. Normalize some naming while here too.
