libfetch from NetBSD's pkgsrc has been imported into lib/fetch, but the objects are embedded into libxbps. Only a public function to fetch files has been implemented: xbps_fetch_file(). The library now is built with -fvisibility=hidden by default, and exported symbols are the ones that use the SYMEXPORT macro. The code works well enough, but will need many more cleanups. --HG-- extra : convert_revision : xtraeme%40gmail.com-20091027004600-0lq9aao67lisbzxv
