#4934: Deprecate topology function creating invalid topologies

 Priority:  medium       |  Milestone:  PostGIS 3.2.0
Component:  topology     |    Version:  2.5.x

-------------------------+---------------------------
 Some topology functions are creating invalid topologies, and are
 documented to do so. They were written before SQL/MM full specification
 was implemented, so it wasn't that easy to create valid topologies.

 Nowadays those functions just make it harder to maintain the codebase as
 there are testcases proving the functionality of some of them still works
 in presence of invalid topologies and we impelment code to ensure invalid
 topologies are still somehow handled. Better stop now :)

 Such functions are (list to be grown I guess):

  - topology.AddEdge (does not do edge linking nor face labeling)
