/* usage:
 * action count(uid): update notice count of uid, return value: integer
 * action get(uid): update notice of uid, return notice data limited to notice count,
 *   and clear notice count. format: object array, see table "notice"
 * action clear(uid, [limit]): clear cache number to notice_count+limit, 
 *   does not affect notice, only user cache. return remain number as int.
 * action add(type, value, context): add a notice, need admin permission now.
 *   **attention**: this is only for web, use notice::add with your own code, 
 *     that function does not require any user permission.
 *   type is an integer, see "notice.inc.php" NOTICE_TYP_*.
 *   value are paired with type, like proid, sqid, uid, .., meaning nothing
 *     with NOTICE_TYP_ALL, but cannot be NULL.
 *   context is what you want. treat as string data so its format
 *     depends on your own.
 *   return 'S' when success.
