this appears to cause problems with the system timer resolution.
This caused a problem with tokens going into the root throttle as
bursts leading to some starvation.
Also changed EnqueueOutgoing to always queue a packet if there
are already packets in the queue. Ensures consistent ordering
of packet sends.
when client and simulator throttles are set. This algorithm also uses
pre-defined burst rate of 150% of the sustained rate for each of the
throttles.
Removed the "state" queue. The state queue is not a Linden queue and
appeared to be used just to get kill packets sent.
* Added TokenBucket.cs to OpenSim, with some fixes for setting a more accurate MaxBurst value and getting a more accurate Content value (by Drip()ing each get)
