Provide for contrib and pgxs modules to install include files.
This allows out-of-tree PLs and similar code to get access todefinitions needed to work with extension data types.The following existing modules now install headers: contrib/cube,contrib/hstore, contrib/isn, contrib/ltree, contrib/seg.Discussion:https://postgr.es/m/87y3euomjh.fsf%40news-spur.riddles.org.uk
