Since this is done directly from ScenePresence, it can lead to a race condition with the simulator loop.
There's no real point doing it anyway since the clear will be done very shortly afterwards by the simulate loop and either there are no events (for a new avatar) or events don't matter (for a departing avatar).
This matches existing behaviour in OdePrim
This was because the parts in scene objects were sometimes not serialized in link order.
This is perfectly fine since the parts still have the right link numbers, but an extra fix to adjust for this
had not been done in the SerialiserModule methods that OAR loading used.
Add regression test for same.

On EntityTransferModule.DoTeleport() there was an IsInTransit() check to prevent multiple simultaneous teleport attempts.
However, the SetInTransit() was only performed later on, which left a window in which multiple threads could pass the IsInTransit() check.
This has been seen in the field and the results aren't pretty.
This commit effectively combines the IsInTransit() and SetInTransit() checks so there is no such window.
More failure cases are made to to call ResetInTransit() to adjust to this move.
This does increase the aggressiveness of shutdown
Also prevents the bot list being locked for a long period, which was preventing commands such as "show bots" from working during shutdown
Still subject to change - if you use this be prepared to change your output code if/when the methods change.
Make new "attachments show" command use this.
If AvatarService appearance data is retrieved over the network, then ServerUtils was attempting to transfer names such as "Wearable 0:0" directly to xml element names, resulting in an exception.
Space is not valid in xml element names. Neither is : in this case since the intention is not to namespace. Using names directly as keys is not a good idea.
To get around this problem this patch escapes and unescapes the element names as appropriate.
This has no impact on existing xml (since it had to be valid in the first place) but allows AvatarService data to be used over the network.
Setting appearance (from simulator to AvatarService) did not suffer this problem since the values are passed in the query string which is already properly escaped.
DuplicateObject() relies on source object having correct link numbers for the duration of the dupe.
Both link and delink can change link numbers such that they are not consistent for short periods of time.
This may be the wrong thing to do but stops lots of log spam in HG setups now that the monitoring is extended to other outgoing calls.
LongCallTime may need to be made configurable.
Viewers 1 and 3 are fine with doing this immediately. However, Imprudence has a small delay (<200ms, >500ms) after receiving the AgentCompleteMovement reply packet on the destination region before regarding that region as the currnet region.
If Imprudence receives a DisableSimulator in this period, it quits.
We are not restoring the full 5000ms delay since this brings back a bug where teleports permanently fail if an avatar tries to teleport back too quickly.
This commit also sends the AgentCompleteMovement packet to the client before telling the source region to release its old agent, in order to further cut down any possibility of the DisableSimulator being recieved before the AgentMovementComplete.
