If this consistently increases then this is a problem since it means the simulator is receiving more requests than it can distribute to other parts of the code.
AgentUpdate packet. This fixes the problem with vehicles not moving forward

Code to fix a potential exception when using different IClientAPIs.

If we're not receiving packets with multiple threads (m_asyncPacketHandling) then this is critical since it will limit the number of incoming UDP requests that the region can handle and affects packet loss.
If m_asyncPacketHandling then this is less critical though a long process will increase the scope for threads to race.
This is an experimental stat which may be changed.
In this new protocol, and as committed before, the viewer is not sent EnableSimulator/EstablishChildCommunication for the destination. Instead, it is sent TeleportFinish directly. TeleportFinish, in turn, makes the viewer send a UserCircuitCode packet followed by CompleteMovementIntoRegion packet. These 2 packets tend to occur one after the other almost immediately to the point that when CMIR arrives the client is not even connected yet and that packet is ignored (there might have been some race conditions here before); then the viewer sends CMIR again within 5-8 secs. But the delay between them may be higher in busier regions, which may lead to race conditions.
This commit improves the process so there are are no race conditions at the destination. CompleteMovement (triggered by the viewer) waits until Update has been sent from the origin. Update, in turn, waits until there is a *root* scene presence -- so making sure CompleteMovement has run MakeRoot. In other words, there are two threadlets at the destination, one from the viewer and one from the origin region, waiting for each other to do the right thing. That makes it safe to close the agent at the origin upon return of the Update call without having to wait for callback, because we are absolutely sure that the viewer knows it is in th new region.
Note also that in the V1 protocol, the destination was getting UseCircuitCode from the viewer twice -- once on EstablishAgentCommunication and then again on TeleportFinish. The second UCC was being ignored, but it shows how we were not following the expected steps...
Revert "One last thing before I stop on this: now not sending ES and EAC to the viewer. Looking in GridProxy, I don't see those messages in the Linden grid."
This reverts commit 1d27c9f4d1.
Revert "EXPERIMENTAL: Trying the other order -- delaying MoveAgentIntoRegion until after the departing agent is released."
This reverts commit fe2487f8d3.
Revert "EXPERIMENTAL: Switch MoveAgentIntoRegion with MakeRootAgent, to see if that eliminates the momentary position at infinity."
This reverts commit 1cb5e31716.
