994e262e3e [media] DocBook/dvbproperty.xml: Document the terrestrial delivery systems
Instead of repeating duplicate parameters to each delivery system,
just add a section for each specific delivery system, showing
what's applicable to each case. This helps userspace app developers
to know what DVB parameters are applicable to each delivery system.

df2692a6dd [media] DocBook/frontend.xml: Recomend the usage of the new API
The old way of setting delivery system parameters were to use
an union with specific per-system parameters. However, as newer
delivery systems required more data, the structure size weren't
enough to fit. So, recomend using the DVBS2API instead.
