We ship pyspatialite - that's not available everywhere and in case we're using
internal spatialite it should be built against that version.

Well, I don't have a good idea what thise clear policy could be.  I'd say there
should be a compelling reason why third party dependencies are included.

pyspatialite is there because of internal spatialite.  Maybe that can be
reconsidered too.  I doubt that anything uses internal spatialite anymore and
there also pysqlite that could be used with spatialite instead of pyspatialite.

owslib is not available everywhere - also AFAIK it's closely releated to
MetaSearch and has the same upstream.

Everything else could be removed from ext-libs AFAICS.
