Browse Source 
- xbps_repository_update_packages: return ENOENT if regpkgdb is NULL
  (no packages currently registered).
- xbps_repository_update_packages: return EEXIST if no updates are
  available.
- xbps_repository_pool: return ENOTSUP if no repositories were
  registered.
- make xbps-{bin,repo} handle ENOTSUP errors.
