leveldb: updated to 1.23


Sync MANIFEST before closing in db_impl when creating a new DB. Add logging with \ 
debugging information when failing to load a version set.
Optimize leveldb block seeks to utilize the current iterator location. This is \ 
beneficial when iterators are reused and seeks are not random but increasing. It \ 
is additionally beneficial with larger block sizes and keys with common \
