  1. *: Wire up L0SubLevels with iterator and version creation 

    This change effectively lowers read amplification in L0 by taking
advantage of knowledge about sublevels contained in
Version.L0SubLevels and using it to create levelIters for each sublevel
instead of directly adding one iterator per file to the mergingIter.
The get_iter is also updated to take advantage of this information.

The Version struct is also updated, as a result of this change, to
hold a reference to an L0SubLevels instance. That reference is initialized
during Version initialization in version_edit.

Most of the test changes are a result of always printing the sublevel
alongside the level for L0.
