Makes the tab restore service persist closed tabs/windows to disk and

reload them when asked.

Sorry for largish looking change. It's made big by refactoring common
code between TabRestoreService and SessionService into a common
superclass. At the same time I removed some dead code and shuffled the
session related classes into a single directory for easier perusal.

BUG=384
TEST=close the browser, start the browser and make sure the new tab
     page shows closed windows/tabs from the previous session.
