* Introduced LBFactory -- an abstract class for configuring database load balancers and connecting to foreign DBs.

* Wrote two concrete implementations. LBFactory_Simple is for general installations. LBFactory_Multi will replace the runtime configuration used on Wikimedia and allow load-balanced connections to any DB. 
* Ported Special:Userrights, CentralAuth and OAI audit to the LBFactory system. 
* Added ForeignDBViaLBRepo, a file repository which uses LBFactory.
* Removed $wgLoadBalancer and $wgAlternateMaster
* Improved the query group concept to allow failover and lag control
* Improved getReaderIndex(), it will now try all servers before waiting, instead of waiting after each.
* Removed the $fail parameter to getConnection(), obsolete. 
* Removed the useless force() function. 
* Abstracted the replication position interface to allow for future non-MySQL support.
* Rearranged Database.php. Added a few debugging features. 
* Removed ancient benet-specific hack from waitForSlave.php
