Comment (by stuarta):

 (In [10847]) Refs #1866. Adds FindBestMplexFreq.

 This add some fuzzy matching to the frequency for dvb-t
 systems. Previously we would ask the card to tune on a
 frequency from the frequency list. This would often not
 be the actually frequency that the mplex is on, but one
 of the offset frequencies, and the card just managed to
 pull itself together and get lock.

 The NIT will have populated that DB with the mplexes
 and their frequencies. So we can check the currently
 tuned frequency against what the NIT provided. If this
 frequency equals either the centre frequency or one of
 the offset frequencies then we use the value we already
 have. If we don't already have a frequency or the frequency
 isn't one of the offsets (as would happen on a repeater mux)
 then just use the frequency we tuned to.
