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...
This adds explicit cap poll handler supporting to the Caps classes rather than relying on callers to do the complicated coding.
Other refactoring was required to get logic into the right places to support this.
This currently prints caps requests received and handled, so that overload of received compared to handled or deadlock can be detected.
This involves making BaseStreamHandler and BaseOutputStream record the ints, which means inheritors should subclass ProcessRequest() instead of Handle()
However, existing inheriting classes overriding Handle() will still work, albeit without stats recording.
"show caps" becomes "show caps list" to disambiguate between show caps commands
Unknown UserUMMAU3 insertion should definitely be removed down the line.
However, I would like a little more time to check the GUN* reduction first, since removing UMMAU3 will make these failures appear as GUN7 instead.
Also bumps GUN6 -> GUN7 and UMMAU2 -> UMMAU3
This is to see the impact that Diva's fixes related to this issue (last one is currently commit c7383688)
You will need to clear your viewer cache for this to have any effect

This is in order to reduce the likelihood of naming clashes, make it easier to filter in/out attributes, ensure uniformity, etc.
All dynattrs in the opensim distro itself or likely future ones should be in the "OpenSim" namespace.
This does alter the underlying dynattrs data structure. All data in previous structures may not be available, though old structures should not cause errors.
This is done without notice since this feature has been explicitly labelled as experimental, subject to change and has not been in a release.
However, existing materials data is being preserved by moving it to the "Materials" store in the "OpenSim" namespace.
This string is returned if a UserManagementModule.TryGetUserNames() cannot find a server-side name binding or a user account for a given UUID.
This is only called when the viewer requests a binding via the UDP UUIDNameRequest message
