=== LinkLocalRegion() ===

 public bool LinkLocalRegion(string regionName, out UUID regionID, out ulong regionHandle,
     out string externalName, out string imageURL, out string reason, out int sizeX, out int sizeY)

Called by a foreign grid that wants to link to a region on this grid.

If AllowTeleportsToAnyRegion = false or regionName is empty:
* Returns the first result from GridService.GetDefaultHypergridRegions()
* Caches it as m_DefaultGatewayRegion
* Returns false with an error reason if no default HG regions exist

Otherwise:
* Calls GridService.GetLocalRegionByName() -- returns false if not found

On success: populates regionID, regionHandle, sizeX, sizeY, externalName (gatekeeperURL + region name), imageURL (region ServerURI + index.php?method=regionImage{uuid}).
