[RFC] dvb-apps ported for ISDB-T

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

I wrote several patches those days in order to allow dvb-apps to properly
parse ISDB-T channel.conf.

On ISDB-T, there are several new parameters, so the parsing is more complex
than all the other currently supported video standards.

I've added the changes at:

http://linuxtv.org/hg/~mchehab/dvb-apps-isdbt/

I've merged there Patrick's dvb-apps-isdbt tree.

While there, I fixed a few bugs I noticed on the parser and converted it
to work with the DVB API v5 headers that are bundled together with dvb-apps.
This helps to avoid adding lots of extra #if DVB_ABI_VERSION tests. The ones
there can now be removed.

TODO:
=====

The new ISDB-T parameters are parsed, but I haven't add yet a code to make
them to be used;

There are 3 optional parameters with ISDB-T, related to 1seg/3seg: the
segment parameters. Currently, the parser will fail if those parameters are found.

gnutv is still reporting ISDB-T as "DVB-T".

needs to review the other applications.

Please review. If everything is right, I intend to commit it likely next week at
dvb-apps.

Cheers,
Mauro.
