IsActive is more appropriate since unack timeout is not due to voluntary logout.
This is in line with operations such as manual kick that do not set the IsLoggingOut flag.
It's also slightly better race-wise since it reduces the chance of this operation clashing with another reason for client deactivation (e.g. manual kick).
This is the same async behaviour as normal logouts.
This is necessary because the event queue will sleep the thread for 5 seconds on an ack timeout logout as the client isn't around to pick up the final event queue messages.
Instead of checking whether the client still exists by trying to retrieve again from the client manager, this patch gets it back from IncomingPacket and checks the IClientAPI.IsActive state.
This alarm can then invoke this to log extra information.
This is used in LLUDPServer to show which client was being processed when incoming and outgoing udp watchdog alarms are triggered.
The packet was actually being handled but not acted on.
This change extends the default timeout for paused clients to 5 minutes
and makes both the paused and non-paused timeout periods configurable.
On the first frame, all startup scene objects are added to the physics scene.
This can cause a considerable delay, so we don't start raising the alarm on scene loop timeouts until the second frame.
This commit also slightly changes the behaviour of timeout reporting.
Previously, a report was made for the very first timed out thread, ignoring all others until the next watchdog check.
Instead, we now report every timed out thread, though we still only do this once no matter how long the timeout.
The only caller is the LLUDP stack and this has to validate the UDP circuit itself, so we know that it exists.
This allows us to eliminate another null check elsewhere and simplifies the method contract
This means that avatar/appearance data of other avatars and scene objects for a client will be sent after the ack rather than possibly before.
This may stop some avatars appearing grey on login.
This introduces a new OpenSim.Framework.ISceneAgent to accompany the existing OpenSim.Framework.ISceneObject and ISceneEntity
This allows IClientAPI to handle this as it can't reference OpenSim.Region.Framework.Interfaces
