- Rework the wrapper support to check libpkg version as well as pkg_install version. - Add libfetch to _prebuild_libs. - There are no new features introduced. Notes: the API is not stable, so basically, do not use libpkg in your projects for now. Also there's no manpage for libpkg yet, because the API will change drastically. I repeat, do not use libpkg for now.
