FS-Cache: Add cache management

Implement the entry points by which a cache backend may initialise, add,
declare an error upon and withdraw a cache.

Further, an object is created in sysfs under which each cache added will get
an object created:

	/sys/fs/fscache/<cachetag>/

All of this is described in Documentation/filesystems/caching/backend-api.txt
added by a previous patch.
