Subject: * Rewrote ClientManager to remove Lindenisms from OpenSim core,
 improve performance by removing locks, and replace LLUDPClientCollection *
 Removed the confusing (and LL-specific) shutdowncircuit parameter from
 IClientAPI.Close() * Updated the LLUDP code to only use ClientManager instead
 of trying to synchronize ClientManager and m_clients * Remove clients
 asynchronously since it is a very slow operation (including a 2000ms sleep)
