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.

On ISDB-T, each layer can have its own independent modulation,
applied to the carriers that belong to the segments associated
with them. So, there's no sense to define a global modulation
parameter.

The ISDB-T differs on its way to implement the hierarchical
transmissions: instead of using a low-priority/high-priority
FEC codes, it does that by using different layers, each layer
with their groups of segments. So, those parameters don't make sense
for ISDB-T.

Instead of using the same delivery system for both Annex A and
Annex C, split them into two separate ones. This helps to support
devices that only support Annex A.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
DVB-C, as defined by ITU-T J.83 has 3 annexes. The differences between
Annex A and Annex C is that Annex C uses a subset of the modulation
types, and uses a different rolloff factor. A different rolloff means
that the bandwidth required is slicely different, and may affect the
saw filter configuration at the tuners. Also, some demods have different
configurations, depending on using Annex A or Annex C.
So, allow userspace to specify it, by changing the rolloff factor.

The patch utility doesn't work with non-binary files. This causes some
tools to break, like generating tarball targets and the scripts that
generate diff patches at http://www.kernel.org/pub/linux/kernel/v2.6/.
So, let's convert all binaries to ascii using base64, and add a
logic at Makefile to convert them back into binaries at runtime.

The av7110 uses an OSD API. Such API is not documented at all. Also,
the osd.h API uses camelCase and some other weird stuff. Also, dvb-core
doesn't recognize it.
I don't see any good reason why we should document it. It seems better
to just let it as-is. If ever needed, it is probably better to write
a different API for dvb-core.
