cachefiles: Implement cache registration and withdrawal
Do the following:
(1) Fill out cachefiles_daemon_add_cache() so that it sets up the cache
directories and registers the cache with cachefiles.
(2) Add a function to do the top-level part of cache withdrawal and
unregistration.
(3) Add a function to sync a cache.
