topology not always schema qualifying functions -- AsTopoJSON, topogeom_Add*

[robe]

These are all I could find scanning thru the topology functions, so this might be all of them

AsTopoJSON makes calls to GetTopoGeomElements qualification.

topogeo_addPoint makes calls to ST_ChangeEdgeGeom without schema qualification.

topogeo_addpolygon makes calls to ST_GetFaceGeometry without schema qualification.

_st_adjacentedges calls GetNodeEdges

addnode(atopology character varying, apoint geometry, allowedgesplitting boolean, setcontainingface boolean DEFAULT false) makes calls to ST_ModEdgeSplit

st_changededgegeo calls to ST_GetFaceGeometry

Thanks robe. Fixed with r12268 in 2.1 branch (2.1.2) and r12269 in trunk (2.2.0)
