cf86ec5874 dvb/parsechannels: fix modulation names 
Some names were incorrect. Authoritative source for
the dvbv5 format taken from v4l-utils' lib/libdvbv5/dvb-v5.c

Aditionally, add the missing setter mapping for the
modulation param.

This change makes ATSC work.

10b020095b dvbsrc: special case detection when DVB-T and T2 seem valid 
There is no way to tell one over the other when parameters
seem valid for DVB-T and DVB-T2 and the adapter supports
both. Reason to go with the former here is that, from
experience, most DVB-T2 channels out there seem to use
parameters that are not valid for DVB-T, like QAM_256

e32a058fcf dvb/parsechannels: do not assume DVB-T from zap file alone

to make an informed guess based on the channel
parameters.

5b1191cb4c dvbsrc: smarten-up delsys autodetection logic 
When there's no explicit delivery system information
for a channel in the channel configuration file and
the user hasn't selected one via setting the delsys
property, we *guessed* it by selecting the last
supported delsys reported by the driver. This change
provides the basis for smarter delsys auto detection
and implements a rule for DVB-T2. Rules for other
delivery systems can be added in _guess_delsys() in
a similar way.

Additionally: Store list of adapter-supported
delivery systems instead of querying the driver each
time this information is needed.

23fccad1fd dvbsrc: dvbbasebin: add 'tune' signal 
It works the same as the 'tune' property that is used only to signal
the element that it should tune, but it is more natural to be used
as a signal rather than a property.

It is also proxied at the dvbbasebin element

01e7e36217 dvbsrc: add preliminary support for ISDB-T/Tb 
ISDB-T and ISDB-Tb (the Brazilian variant) are the
terrestial DTV standards used by Japan, Philippines,
Maldives, Thailand, most South American countries
and Botswana. Changeset adds the set of previously
missing (and required) ISDB-T parameters, adapter
and frontend setup logic and proxies the new
properties on dvbbasebin.

Tested to work with the live aerial broadcast by
Tv Paraíba HD in Campina Grande (Brazil).
