Ok, so.

1- scanning is up to the application
2- we need to add the following methods to GstTuner
  a- (int) get_max_frequency() - so application knows what the maximum value
for 'set_frequency' (the next step would be loop around)
  b- (int) get_min_frequency() - to know the min value
  c- (step, units) get_frequency_step() - it is the resolution of the tuner
* for all of them there is something similar in v4l2 spec

3- Danilo, instead of have a get_max_signal_strength, I think we could have
pre-defined values (for example, from 0 to 100, or else from 0 to 1000). I mean
just need to be documented in GstTuner interface, and the plugins would have to
convert different strength ranges for it. 
* I think it is like this already for GstTuner (I'm not sure)
* I think it is like this for v4l2 spec (ie there is a defined range)
