[PATCH 07/15] [media] DocBook/dvbproperty.xml: Document the remaining S2API parameters

[Mauro Carvalho Chehab <mchehab@redhat.com>]

There were lots of DVB S2API parameters that were never documented.
Let's add a definition for all of them, based on what's currently
used inside the core and the drivers.

The description here is not complete nor perfect, so patches
improving it are welcome.
