Implement the function that shapes extents to map onto the granules in a
cache file.
When setting to fetch data from the server to be cached, the extent will be
expanded to align with granule size and cut down so that it doesn't cross
the boundary between a non-present extent and a present extent.
Implement the new fscache I/O backend API in cachefiles. The
cachefiles_object struct carries a non-accounted file to the cachefiles
object (so that it doesn't cause ENFILE).

Replace the object management state machine with something a lot simpler.

Keep track of the size of a file that we're caching as last set
independently on the server by another client. As long as this does not
change, we can make the assumption that anything over that boundary, if not
represented in the local cache, will not be represented on the server
either and can b
Rewrite the fscache I/O API by introducing a number of new routines based
on a number of principles:
(1) The cache provides *only* write-to-cache and read-from-cache calls for
transferring data to/from the cache.
(2) The bufferage for I/O to/from the cache is supplied with an iov_iter.
Remove fscache_wait_on_invalidate() as the invalidation wait is now built into
the I/O path.

Remove fscache_check_consistency() as that allows the netfs to pry into the
inner working of the cache - and what's in the cookie should be taken as
