Another dvbbasebin optimization to do (which maybe should go in a different bug
report) is to store the observed stream-PID for each program in a configuration
file. That way we don't have to wait for the PMT to know which PID we should
activate.

Ex:
PROGRAM_1:<pmt_pid>:<program1_pes_pid1>,<program1_pes_pid2>,....

That will allow us to start with a reduced number of PID (filtering activated
on the frontend). The probability the PMT PID and program stream PID changed
over time is very low. If they do change, we can still go back to the old logic
(at the expense of latency).

Obviously a system-wide daemon would help with that ... but in 10+ years of
dvb-linux nobody has agreed on a common solution :(
