-------------------------------------------------+-------------------------
 This patch reworks the code that sets up listeners for EIT.  While testing
 the EITpf timing code I found a problem when recording two programmes on
 the same multiplex and tracked it down to the way listeners are set up.
 This patch is almost completely independent of the EITpf timing patch
 (#10101) apart from one place in DVBStreamData::UpdateEITListeners where
 EIT listening is enabled if _dvb_eit_listeners.size() is non-zero.

 The changes move responsibility for adding and removing listeners down
 from StreamHandler to the derived classes of MPEGStreamData.  I have
 tidied up the code for DVBStreamData but I've kept the changes to
 ATSCStreamData to a minimum because I couldn't test them.

 The problem with the existing code was primarily that
 StreamHandler::UpdateListeningForEIT used the _eit_pids variable in
 StreamHandler and updated it within the loop, using the new value for the
 next stream.  That meant that EIT filtering could be on or off depending
 on the order of the streams in _stream_data_list.  The fact that passive
 EIT scanning could be turned off during multirec recordings probably
 wouldn't make much difference since it is
 all statistical anyway.
