This happened because these notifications (the UDP packets) can only be sent to Root Agents. But the notifications were done in OnClientLogin(), at which point the client is still a Child Agent. Since a FireAndForget is used, it became a race condition as to whether the packets would be sent before or after the client became a Root Agent.
To fix this, we now only send the notifications once the client becomes a Root Agent for the first time.
This can affect which region to use. E.g., returning users may be allowed to enter any region, whereas users from other grids will have to enter a gateway region. Previously per-user decisions were only made later, but by then it's too late to change which region the user enters.
This is to prevent an immediate problem in http://opensimulator.org/mantis/view.php?id=7035 where a development code bug occasionally overlays all the existing parcels with a blank parcel owned by the estate manager and to gather more data.
My guess is that this parcel is being created by the new code in LandManagementModule.GetLandObject(), probably some race between threads since this only happens occasionally.
Adds regression tests for this case and for parcel subdivide.
This is because the alpha texture is not in the cache, we must continue to have the fallback of looking for these and other persisted bakes in the asset service.
Relates to http://opensimulator.org/mantis/view.php?id=6927
This is causing many issues on OSGrid, possibly due to teleporting timing differences with simulators hosted in different places or HG teleports
Added a bit more logging for debug purposes.

Changed UuidGatherer to use 'sbyte' to identify assets instead of 'AssetType'. This lets UuidGatherer handle Materials, which are defined in a different enum from 'AssetType'.
Add new region crossing code to varregion
Conflicts:
OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs
OpenSim/Region/Framework/Scenes/ScenePresence.cs
Rename 'RegionWorldLocX' to 'WorldLocX' and same for Y and Z.
This keeps the downward compatibility and follows the scheme of 'region'
and 'world' location naming that is happening in the Util module.
- Parts of region crossing code
- New bakes handling code
- Bakes now sent from sim to sim without central storage
- Appearance handling changes
- Some changes to sitting
- A number of unrelated fixes and improvements
* Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice.
* Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers
* Added CircularBuffer, used for CPU and Memory friendly rate monitoring.
* DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user, It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.
