Because of historic reasons, there are two separate directories with
V4L stuff. Most drivers are located at driver/media/video. However, some
code for USB Webcams were inserted under drivers/usb/media.

This makes difficult for module authors to know were things should be.
Also, makes Kconfig menu confusing for normal users.

This patch moves all V4L content under drivers/usb/media to
drivers/media/video, and fixes Kconfig/Makefile entries.

Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER).
This mode allows the user to select both languages of a bilingual transmission,
one language on the left, one on the right audio channel. If there is no
bilingual transmission, or it is not supported, then this mode should act like
V4L2_TUNER_MODE_STEREO.
This mode is introduced for PVR-like drivers where it is useful to be able to
record both languages of a bilingual broadcast.

Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
  i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is
a user level command and not to be used internally. It wasn't called at
all anyway.

was never actually defined as far as I can see, so the code was ifdef'd out,

The bt856 driver has a register cache much larger than needed.  We really only
write to 3 registers, so a 32-byte cache is a bit too much.  We can be just as
efficient with a 6-byte cache.  We could even do with a 3-byte cache, but at
the cost of additional arithmetics arguably not worth the spared 3 bytes.

Also, 4 of the 6 other members of the bt856 data structure were not used
anywhere, so we can as well drop them for an additional 16 bytes of memory
spared.

When grabbing composite video with Iomega Buz, the stock driver will
prevent grabbing from the same input twice in a row, forcing the user to
switch inputs before anything useful can be grabbed again.  It is caused by
some optimization code in the input selection parts, and triggered by the
saa7111_command() executing cmd 0.  The attached patch will remedy this by
disabling cmd 0 altogether; a fix that has no found negative effects on the
rest of the code.  In fact, saa7110.c does the exact same thing.

Some chipsets have several problems when pci to pci transfers are activated
on overlay mode. the option no_overlay allows disabling such feature of
the driver, in favor of keeping the system stable.
The default is to use pcipci_fail flag defined on drivers/pci/quirks.c.
It also allows the user to override it by forcing disable overlay or forcing
enable. Forcing enable may generate PCI transfer corruption, including disk
mass corruption, so should be used with care.
Added a text description to this option and make messages looks the same at
both bttv and saa7134 drivers.
