This adds USB message read checksumming to protect against

It also adds a read length check to avoid returning garbage from
the buffer, if the device truncated the message.

AF9035 is integrated DVB USB interface and DVB-T demodulator.
Integrated demodulator is AF9033 and its driver is attached
runtime as a own module.

Driver currently supports only one device,
TerraTec Cinergy T Stick [0ccd:0093].

TerraTec Cinergy T Stick is based of Afatech AF9035 +
Infineon TUA 9001 silicon tuner.

Some apps which use read() start the streaming through a call to poll(),
this means that if another app has already claimed the device for streaming
(through for example a s_fmt, or a reqbufs), that the poll should fail instead
of getting passed through to vb2_poll.

We only check for this when the app is polling for reads, so that ctrl events
still work.

stb0899: fix the limits for signal strength values

stb0899_read_signal_strength() adds an offset to the result of the table lookup.
That offset must correspond to the lowest value in the lookup table, to make sure
the result doesn't get below 0, which would mean a "very high" value since the
parameter is unsigned.
'strength' and 'snr' need to be initialized to 0 to make sure they have a
defined result in case there is no "internal->lock".

It is mostly copy/paste of the 520e code with setting GPIO7 removed
(no LED light).

I've worked on just released vanilla linux-3.3.0 kernel, so there may
be 1/2 lines offset to the internal working source, but most of the
code should apply cleanly.

I was able to get the DVB-C working (tuned and watched TV). Haven't
tested DVB-T (no signal atm).

Special thanks to everybody who worked on the code and to Antti
Palosaari and Devin Heitmueller who provided essential support on irc.

... + analog parts.
Analog is not supported currently. Only DVB-T and DVB-C.

There seems to be still	problems for locking DVB-C channels which have
strong signal. Attenuator helps. I think it is demodulator IF/RF AGC
issue. Lets fix it later. Patches are welcome.

I found one more place where -EINVAL is used instead of -ENOTTY:

Note that drivers/media/dvb/dvb-core/dvbdev.c has the same code, but as far as
I can tell DVB is still using -EINVAL for unknown ioctls so I didn't change
that.
