    my $control_library = Koha::Policy::Holds->holds_control_library( $item, $patron );

Given I<Koha::Item> and I<Koha::Patron> objects, this method returns a library id, for
the library that is to be used for calculating circulation rules. It relies
on the B<ReservesControlBranch> system preference.
