------- Additional Comments from Dumitru Daniliuc <dumi at chromium.org>
Cleaning up the DB classes to make it easier to move code out of them into new
classes: removing unused #includes, replacing #includes in header files with
forward class declarations as much as possible, removing 'friend' declarations,
and adding getters for private fields where necessary.
