Partial rewrite of the login server's auth system.

 * replaced the cyclic, size-limited auth_fifo data structure with the more appropriate DBMap-based alternative (stops some erratic behavior)
 * added code to simulate the pseudo-status "online on login server"
 * auth data will now expire after 30 seconds instead of persisting
 * better-than-aegis handling of login cancellation (the server will wipe all previous auth data instead of making you wait for it to expire)
 * proper status message - no more generic "rejected from server", now you'll get "the server still recognizes your last connection"
 * fixed a typo in r10110 which caused disconnect timer removal to fail
 * split off some parsing code to login_auth_ok() and login_auth_failed()
 * extended the auth confirmation packet so that the login_id1/2 values are sent along with the associated account id (stops charserver from making wrong choices if two incoming sessions have the same account id)
 * fixed a bug in the disconnect part of the main charserver parsing loop, where a non-authed client would erase the online db entry for a client that's already online, thus bypassing any dual-login checks
 * added code to stop the waiting_disconnect timer when the associated online entry is removed right away, instead of doing checks later
 * removed code that would periodically wipe the online status of clients that are in the auth process (producing yet more erratic behavior)
 * commented out some TXT-only reconnect prevention code (bugreport:1281)
