* Changed EXIT_SUCCESS back to 0 in console.c to avoid an unnecessary include.

* Fixed gm_account_db not being deallocated in login-converter.c.
* Refactoring names and documentation in db.h/db.c:
  - changed 'struct dbt' to 'struct DBMap' and 'DB' to 'DBMap*'
  - changed 'struct db' to 'struct DBMap_impl' and 'DB_impl' to 'DBMap_impl*'
  - changed COUNT to DB_COUNTSTAT and made it's existence not depend on DB_ENABLE_STATS
  - removed some @see links and corrected small typos in the documentation
