The cx23885/7/8 PCIe bridge has an internal AVCore modelled on
the cx2584x family. Many of the registers positions are identical
but some moved. The register values are also different because
the different bridges run at different clock rates.

cx25840_read4 reads a little-endian 32-bit value whereas cx25840_write4 writes
the 32-bit value as big-endian. Convert write4 to use little-endian as well
(that's the correct endianness).

Whenever the 0x80b register is used the microcontroller should be reset.

Audio muting for the tuner input was implemented by stopping the audio
microcontroller and restarting it on unmute. However, it appears that this
method can actually crash the audio firmware. It's rare and seems to
happen with NTSC only.
It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

Add -include linux/version.h to the cflags. Now code can have backward
compatibility test without including compat.h first.
Linux headers included from compat.h are removed, so that code will get
the same headers when compiling in v4l-dvb as it does in the kernel.
Many drivers have compat.h moved to the end of their include list, as
this lets compat.h do things it can't do at the beginning. Such as test
of something is defined to include compat code, or to put a wrapper
around a function without changing the function's name.

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.

- Added VIDIOC_S_AUDIO to set the audio inputs separately.
- Removed AUDC_SET_INPUT.
- Made the video inputs much more general.
- Removed cardtype CID and replaced with a CID to enable
the PVR150 workaround. The cardtype is no longer necessary
with the general video input change.
- Update VIDIOC_LOG_STATUS output to show the video and
audio inputs separately.

- Calculate the audio master clock registers from the actual
frequencies. This simplifies the code and it also prepares
for adding CGC2 support.
- VIDIOC_INT_AUDIO_CLOCK_FREQ now receives an u32 instead of
an enum. It is more generic and actually easier to implement.

- Makes V4L compile with kernel 2.4
- em28xx doesn't compile with 2.4 kernels. Additional work is
necessary to make it compile.
