Split pkgs required by xbps-base-chroot, as it was made in Fedora.

- Added an additional shell func to add full (build/run), build
  or run time dependencies to packages. An optional third parameter
  can be used to specify other version than the one set in
  the depends file.
- Use a "depends" file in package directory to specify minimum
  required ABI/API version for a package, so that there's no need
  to set the version all the time in pkgs.
- Updated bash to 4.0.
