Remove the old (Remoting) region crossing code. Fix the new code to

pass script state and assembly again properly. Reintroduce respecting tht
TrustBinaries flag. Changes the interregion protocol! No version bump
because it was broken anyway, so with a version mismatch it will simply
stay broken, but not crash. Region corssing still doesn't work because
there is still monkey business with both rezzed prims being pushed across
a border and attached prims when walking across a border. Teleport is
untested by may work.
