(pyPassphraseCb, pyme_set_passphrase_cb, pyProgressCb, pyme_set_progress_cb, pyStatusCb, pyme_set_status_cb, _pyme_interact_cb, pyDataReadCb, pyDataWriteCb, pyDataSeekCb, pyDataReleaseCb, pyme_data_new_from_cbs, _pyme_assuan_data_cb, _pyme_assuan_inquire_cb, _pyme_assuan_status_cb): Likewise. * lang/python/setup.py.in: Make 'gpgme-config' emit the correct cflags, and SWIG generate code to release the GIL before calling us.
