This release should contain only two small bugs.
- Update MASTER_SITES to use the https version of bitbucket.
- Do not set FETCH_ARGS to a custom value, as it does not seem
to be needed anymore.
- Kind of revert the fix for PR 159690 now that bitbucket seems
to have changed its mind once again and changed the naming
scheme of the top-level directory in the tarball.
