Subject: Fixes Mantis #3260. Thank you kindly, MCortez for a patch that:
llSetHoverHeight() should not clamp the x/y position of an object the way
MoveTo does, and it should recalculate the absolute height to hover at as an
object moves to reflect the current ground/water height under it. Correctly
implementing required adjusting the Physics interfaces and implementing at
the physics plug-in level. The attached is a patch that correctly implements
llSetHoverHeight() including updates to the ODE physics plug-in.
