1. Maximum size of CacheLongKeyLIRS now includes approximate size of the cache itself. It doesn't have any significant impact when large objects are cached, but it prevents excessive memory usage when very small objects are cached.
2. Incorrect sizes of objects passed to MVStore.chunksToC are corrected.
3. Default object size is changed from 1 byte to 16 bytes (typical size of java.lang.Object).
4. Size of a cached object is now stored as long to prevent possible overflows (with large cached arrays, for example).
