PostGIS geometry editing

Goal: Implement ​PostGIS geometry editing functionality in GRASS GIS (wxGUI digitizer and v.edit module)

See also OGR Interface and wxGUI vector digitizer roadmap.

Tasks

1. Attribute table (write) access for OGR-linked vectors (direct or linked by v.external) (implemented in r47225)
2. Improve OGR interface write access (in progress)
3. Implement PostGIS driver on the top of OGR driver to allow fully-featured editing (including topology)
4. Add more...

Roadmap

1. Read access (geometry)
2. Write access (geometry)
