Subject: Mantis#1965. Thank you kindly, HomerHorwitz for a patch that: Places
 touched: - Added two events for in-packets to LLCLientView:
 RegionHandleRequest and   ParcelInfoRequest - Added sending of two
 out-packets to LLCLientView: RegionIDAndHandleReply and   ParcelInfoReply. -
 Scene handles the RegionHandleRequest, LandManagementModule the  
 ParcelInfoRequest - Added inter-region request for LandData by RegionHandle
 and local position.   This was implemented as XML-RPC request. The returned
 LandData isn't   complete, it only contains the data necessary for answering
 the   ParcelInfoRequest - Added new CAPS (0009) for RemoteParcelRequest and
 some methods for LandData   handling to LandManagementModule - Added methods
 for fake parcelID creation and parsing to Util - Fixed missing implementation
 of interface methods. - Added new file:    
 OpenSim/Framework/Communications/Capabilities/LLSDRemoteParcelResponse.cs  
 NOTE: This is part of the patch, too. Due to the many places touched, I would
 consider this patch as experimental.
