Found an odd bug while implementing support for the HVR1850 that
lead to jerky video during the first capture, if the encoder was
not initialized early. I've modied the driver to configure the
encoder early, and this avoids the issue - a reasonable workaround.

Regression tested against the HVR1800 and soon to be added HVR1850

Since the conversion to subdev in Oct 2010 the audio controls have
not functioned correctly in the cx23885 driver. Passing values of
0-3f did not translate into meaningfull register writes. I've
converted the cx23885 driver to match the cx25840 volume control

For frontends with ISDB-T, DVB-T2, CMDBTH, etc, some code is
needed, in order to provide emulation. Add such code, and check
if the desired delivery system is supported by the frontend.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Get rid of using ops->info.type defined on DVB drivers,
as it doesn't apply anymore.

Currently, one driver (cxd2820) supports more than one different
info.type, as it can be used for DVB-T/T2 and DVB-C. There are more
drivers like that to come. So, the same frontend will have

different DVBv3 types, depending on the current delivery system.

This breaks the existing logic at dvb_frontend, that assumes that
just one delivery system DVBv3 type is supported by all delsys.

In order to easy the DVBv3->DVBv5 conversion, an ancillary function
that maps DVBv3 delivery systems into DVBv5 were added.

Also, on all places, except for the event logic, the DVBv5 cache
will be used to check parameters, instead of the DVBv5 copy.

This patch simplifies the cache sync logic, and warrants that the
cache will be in a clear state at DVB frontend register. This way,
ops->info.type will be filled to reflect the first delivery system,
providing backward compatibility support for it.

For example, in the cases like cxd2820, where the delivery systems
are defined as:
        .delsys = { SYS_DVBT, SYS_DVBT2, SYS_DVBC_ANNEX_A },

A pure DVBv3 will be able to use both DVB-T and DVB-T2, as, at
DVB cache clear, the ops->info.type will be equal to FE_OFDM.

However, DVB-C won't be visible. A quick workaround would be to
do a DVBv5 call to set the delivery system to SYS_DVBC_ANNEX_A.

After such call, ops->info.type will be equal to FE_QAM, and a
DVBv3 application will see the frontend as a DVB-C one.

This change is there in order to prepare the code to avoid calling
 dvb_frontend_ioctl_legacy() from FE_SET_PROPERTY.

A call to dvb_frontend_ioctl_legacy() would require to update the
DVBv3 cache without need, mangling calls for newer delivery system
without any reason.

No functional changes here.

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.

The cx23885-dvb driver has a dirty hack:
	1) it hooks the DVBv3 legacy call to FE_SET_FRONTEND;
	2) it uses internally the DVBv3 struct to decide some
	   configs.

Replace it by a change during the gate control. This will
likely work, but requires testing. Anyway, the current way
will break, as soon as we stop copying data for DVBv3 for
pure DVBv5 calls.

Compile-tested only.
