As media/dvb will be removed, move it to a proper place.

Now that this field is deprecated, and core generates it for
DVBv3 calls, remove it from the drivers.
It also adds .delsys on the few drivers where this were missed.

Just like set_frontend, use the dvb cache properties for get_frontend.
This is more consistent, as both functions are now symetric. Also,
at the places get_frontend is called, it makes sense to update the
cache.
Most of this patch were generated by this small perl script:
while (<>) { $file .= $_; }
if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) {
my $get = $1;
$file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g;
}
print $file;
Of course, the changes at dvb_frontend.[ch] were made by hand,
as well as the changes on a few other places, where get_frontend()
is called internally inside the driver.
On some places, get_frontend() were just a void function. Those
occurrences were removed, as the DVB core handles such cases.

Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.
Also, fill the supported delivery systems at dvb_frontend_ops
struct.

Creates a DVBv5 get_frontend call, renaming the DVBv3 one to
get_frontend_legacy(), while not all frontends are converted.
After the conversion for all drivers, get_frontend_legacy()
will be removed.

Passing DVBv3 parameters to set_frontend is not fun, as the
core doesn't have any way to know if the driver is using the
v3 or v5 parameters. So, rename the callback and add a new
one to allow distinguish between a mixed v3/v5 paramenter call
from a pure v5 call.
After having all frontends to use the new way, the legacy
call can be removed.

pointer field inside dvb_frontend
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
always, before you could assign the static pointer directly, which was
dangerous.

Some code had pointless gotos that just didn't make any sense. They didn't
make the code smaller, or faster, or easier to understand.
