A handful of minor changes:

    * Removed the PMList typedef, in favor of the same naming scheme other
      structs use 'pmlist_t'
    * Added a time stamp on debug output, to make it more informational
    * Moved alpm_db_register to _alpm_db_register, making the public function
      not take a callback parameter
