David Steele 6b409d049e Update default block size and super block values based on testing.
Block sizes are incremented when the size of the map becomes as large as a single block. This is arbitrary but it appears to give a good balance of block size vs map size.

The full backup super block size is set to minimize loss of compression efficiency since most blocks in the database will likely never be modified. For diff/incr backup super blocks, a smaller size is allowable since only modified blocks are stored. The overall savings of not storing unmodified blocks offsets the small loss in compression efficiency due to the smaller super block and allows more granular fetches during restore.
