RSL: Allow disabling of BCCH/SACCH filling for given SI type
If we want to instruct the BTS to stop sending a given SI, we must be
able to send the respective BCCH INFO / SACCH FILLING with a header but
without any L3 data IE. This patch enables the related functions to do
this whenever their data argument points to NULL.
