Ability to set different size fanout multipliers for every level. Summary: There is an existing field Options.max_bytes_for_level_multiplier that sets the multiplier for the size of each level in the database. This patch introduces the ability to set different multipliers for every level in the database. The size of a level is determined by using both max_bytes_for_level_multiplier as well as the per-level fanout. size of level[i] = size of level[i-1] * max_bytes_for_level_multiplier * fanout[i-1] The default value of fanout is 1, so that it is backward compatible.

Change namespace from leveldb to rocksdb Summary: Change namespace from leveldb to rocksdb. This allows a single application to link in open-source leveldb code as well as rocksdb code into the same process.
