Unlike LL, OpenSimulator currently uses this stat to record the number of prims in the physics simulation, even when they are at rest.
Added regression test for this case.
This check is necessary to close a race condition where the CompleteAgentMovement processing could proceed when the UseCircuitCode thread had added the client to the client manager but before the ScenePresence had registered to process the CompleteAgentMovement message.
This is most probably why the message appeared to get lost on a proportion of entity transfers.
A better long term solution may be to set the IClientAPI.SceneAgent property before the client is added to the manager.
There is a possibilty that some V2 teleport failures are due to the viewer triggered CompleteMovement thread not seeing the change of m_originRegionID by the UpdateAgent thread.
This is specified in the MaxOutgoingTransferVersion attribute of [EntityTransfer] in OpenSim.ini, see OpenSimDefaults.ini for more details.
Default remains "SIMULATION/0.2"

Need an info message since this is currently important in detecting teleport issue when not at debug log level.
CompleteMovement message occurs before MakeRootAgent() one did
This reverts commit c7ded0618c.
This proves not to be necessary - the necessary checks are already being done via QueryAccess() before cross or teleport
This is necessary because the hypergrid groups checks (as referenced by estates) require an agent circuit to be present to construct the hypergrid ID.
However, this is not around until Scene.NewUserConnection(), as called by CreateAgent() in EntityTransferModule.
Therefore, if we're dealing with a hypergrid user, delay the check until NewUserConnection()/CreateAgent()
The entity transfer impact should be minimal since CreateAgent() is the next significant call after NewUserConnection()
However, to preserve the accuracy of query access we will only relax the check for HG users.
This occurs on v2 teleport since the source region now waits 15 secs before closing the old child agent, which could still receive chat.
This commit introduces a ScenePresenceState.PreClose which is set before the wait, so that ChatModule can check for ScenePresenceState.Running.
This was theoretically also an issue on v1 teleport but since the pause before close was only 2 secs there, it was not noticed.
Also separates out log messages to distinguish between close not finding an agent and wrong auth token, and downgrades former to debug and latter to warn
If this is attempted, they get a "Try moving closer. Can't sit on object because it is not in the same region as you." message instead, which is the same as current ll grid.
Sitting on ground is okay, since viewer navigates avatar to required region first before sitting.
This approach has problems if a client quits without sending a proper logout but then reconnects before the connection is closed due to inactivity.
In this case, the DoNotCloseAfterTeleport was wrongly set.
The simplest approach is to close child agents on teleport as quickly as possible so that races are very unlikely to occur
Hence, this code now closes child agents as the first action after a sucessful teleport.
IncomingCloseAgent() now sets the scene presence state machine properly, which is necessary to avoid races between multiple sources of close.
Hence, it's also necessary for everyone to consistently call IncomingCloseAgent()
Calling RemoveClient() directly is currently generating an attention-grabbing exception though this right now this is harmless.
