varregion: elimination of Constants.RegionSize from all over OpenSimulator.

Routines in Util to compute region world coordinates from region coordinates
as well as the conversion to and from region handles. These routines have
replaced a lot of math scattered throughout the simulator.
Should be no functional changes.
