Add a reference counter on the cache_entry. Its value will be atomically increased and decreased via the retain_entry and release_entry functions. The release_entry function has two distinct versions, release_entry_locked and release_entry_unlocked that should be called when the cache lock is already taken in write mode or not (respectively). In the unlocked case the cache lock will only be taken in write mode on the last reference of the entry (before calling delete_entry). This allows to limit the amount of times when we need to take the cache lock during a release operation.
