[svn-r12935] Added list-to-btree conversion, changed SOHM apis, and pushed SOHM table

version and size information into the superblock to eliminate a read when
loading it.

This is a file format change, and hopefully the last one (knock on wood).

Tested on kagiso and Windows (mostly just a SOHM change).
