This is to help relieve a race condition when an agent teleports then immediately attempts to teleport back before the source region has properly cleaned up/demoted the old ScenePresence.
This is rare in viewers but much more possible via scripting or region module.
However, more needs to be done since virtually all clean up happens after the transit flag is cleared .
Possibly need to add a 'cleaning up' state to in transit.
This change required making the EntityTransferModule and HGEntityTransferModule per-region rather than shared, in order to allow separate transit lists.
Changes were also required in LocalSimulationConnector.
Tested in standalone, grid and with local and remote region crossings with attachments.
This includes prim count, script count, avatar count, etc.
Information is currently the same as "show stats", though show stats can only show one scene at a time because it listens for the latest outgoing stats packet (a bad approach that needs to change).
Might be better to tie this module into the other stats module to display arbitrary stats rather than fetching directly from scene.SimStatsReporter.
Console command is "show scene" because "show region" already exists for the grid service, which is unfortunate.
Might need to make a distinction between "scene" relating to a live scene and "region" relating to more static region data (url, coords, etc.)
The reference is not guaranteed to be there when AddRegion() is called but will definitely be present at RegionLoaded() if it's going to be present at all.
This is because the attachments module code was setting the 'object slam' bit by using PermissionMask.All
Solution here is to route the attachment item creation call through the existing inventory code in BasicInventoryAccessModule rather than copy/pasted code in AttachmentsModule itself.
This is to eliminate possible race conditions if two teleport calls are made concurrently, where at least one is a local teleport.
This is pretty much impossible on a manual user teleport but can happen on script-invoked teleports.
This was previously over-inflated because adding a region to the NE of the root region resulted in double counting of regions already added.
An accurate extent will also be necessary for other purposes.
An adaptation of part of Garmin's patch from http://opensimulator.org/mantis/view.php?id=5975, thanks!
Flag only written if the SW corner OAR is saved - this is the only one that captures object data presently (though not land or terrain data).
This adds an IRegionCombinerModule interface and the necessary methods on RegionCombinerModule
Without this, LL 3.3.1 continually pushes LLInventoryModelFetchDescendentsResponder::error 499 to its log.
This cap will be ignored by older viewers - UDP inventory will work normally.
