minor: correct attachment spelling mistake in log message in HGEntityTransferModule.OnIncomingSceneObject()
minor: Clean up tabbing and spacing issues in OpenSim.ini.example
minor: Make OpenSimDefaults.ini consistent (spacing and tabs to spaces)
minor code formatting for the sake of consistency and readability
refactor: rename Scene.IncomingCloseAgent() to CloseAgent() in order to make it clear that all non-clientstack callers should be using this rather than RemoveClient() in order to step through the ScenePresence state machine properly.

Adds IScene.CloseAgent() to replace RemoveClient()
refactor: Rename Scene.AddNewClient() to AddNewAgent() to make it obvious in the code that this is symmetric with CloseAgent()
minor: Disable logging left active on regression test TestSameSimulatorIsolatedRegionsV2()
VarRegion: change RegionInfo storage of region coordinates from region
count number to integer world coordinates.
Added new methods RegionWorldLoc[XY].
Refactored name of 'RegionLoc*' to 'LegacyRegionLoc*' throughout OpenSim.
Kept old 'RegionLoc*' entrypoint to RegionInfo for downward compatability
of external region management packages.
VarRegion: add RegionSize[XYZ] to RegionInfo.cs.
Update RegionInfo parameter and serialization routines to serialize
the region size if it is not the LegacyRegionSize.
varregion: go back to using Constants.RegionSize so as not to break
external modules. People shouldn't use it but don't want to cause
too much breakage of legacy modules.
Remove time based terrain storage in SQLite so revision number can be used
to denote terrain format revision.
Add terrain DB format revision codes to ISimulationDataStore.cs.
Setup so legacy compatible terrain storage and fetch is possible while
allowing future format extensions.
varregion: serious rework of TerrainChannel:
    -- addition of varaible region size in X and Y
    -- internal storage of heightmap changed from double[] to short[]
    -- helper routines for handling internal structure while keeping existing API
    -- to and from XML that adds region size information (for downward compatibility,
        output in the legacy XML format if X and Y are 256)
Updated and commented Constants.RegionSize but didn't change the name for compatibility.
