Diff update osm transportation name network linestring (#996)
Replacing materialized view by a tables with update from trigger on change only. Differential update of `osm_transportation_name_linestring`, `osm_transportation_name_linestring` and `osm_transportation_name_linestring_genX`). At the end of the transaction the dependent rows are updated. The goal is to update more quickly the content of derivated tables by just updating the changing content. It replaces the update of materialized view because their need a full recompute (with lock issue). It is the last part of the replacement of materialized view for the transportation layer. It addresses #814 and a part of #809.pull/997/head
