The program_number attribute was overloaded, trying to indicate both the currently playing program, and the program requested via the "program-number" property. The end result was that setting the property didn't work (see #690934). I added a new requested_program_number field rather than reviving the current_program_number field because it seemed this would result in fewer changes overall and be less confusing. It breaks symmetry with the "program-number" property, but it retains parallels with the likes of program->program_number. Because gst_ts_demux_reset is called after the properties have been parsed, requested_program_number is initialised in gst_ts_demux_init. Whether this is exactly the right place, I don't know.
