Give DiskLruCache an API to edit a snapshot. When an HTTP conditional GET results in a cache hit (ie. 304 Not Modified) we want to update the cache's HTTP headers with the server's latest. Unfortunately prior to this change DiskLruCache had no mechanism to atomically change a snapshot. This change gives us a mechanism to upgrade from a snapshot (read only) to an editor (read/write).
