shelve: rename method for data write/read

There are no user of this code nor any code related to obsshelve in the
extensions right now, so we rename the function before using them.

Note: The shelvedfile looks a bit strange. We should probably refactor it,
however, this is an adventure for another series.

import pkgutil
__path__ = pkgutil.extend_path(__path__, __name__)
