* Avoid extra copies in threading_field_to_data (Dominik Charousset)
Passing the `broker::data` paramter for `threading_field_to_data` by
value forces copies. However, the function only needs const access to
its parameter. Hence, taking the parameter as const-ref is the logical
choice and avoids unnecessary copies of individual data fields.
