configure.ac: check weston vs. libweston versions
Check that the defined versions for Weston and libweston are consistent and according to the version bumping rules: - In pre-release and only pre-release versions the weston and libweston may differ - when they differ, libweston version must be exactly (weston.major+1).0.0 - otherwise, the versions must be exactly the same.
