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.
