[media] dvb: Add DVBv5 statistics properties
The DVBv3 statistics parameters are limited on several ways:
- It doesn't provide any way to indicate the used measure,
so userspace need to guess how to calculate/use it;
- Only a limited set of stats are supported;
- Can't be called in a way to require them to be filled
all at once (atomic reads from the hardware), with may
cause troubles on interpreting them on userspace;
- On some OFDM delivery systems, the carriers can be
independently modulated, having different properties.
Currently, there's no way to report per-layer stats.
To address the above issues, adding a new DVBv5-based stats API.
While here, correct inner code nomenclature on a few places.
