Comment(by strk):

 The attached patch implements proper cloning of POINTARRAY elements in
 lwpoint_clone, lwline_clone and lwpoly_clone. Serialized pointlist is
 _not_ copied but simply marked as READONLY. A more integrated approach
 might be porting the readonly/non-readonly (or better _owned_/_not_owned_
 flags in the LWGEOM structure itself, but I'm not sure it'd save us much.

 Conceptual and practical reviews of the patch are welcome.
 If we like the idea, it should be better documented that lwgeom_clone does
 not copy the _serialized_points_, not the POINTARRAY (as currently
 documented).
