Videodev now is capable of better handling V4L2 api, by
processing V4L2 ioctls and using callbacks to the driver.
The drivers should be migrated to the newer way and the older
one will be obsoleted soon.

Some saa7115-based cards use a different crystal frequency and a different
audio clock generation. Add a new VIDIOC_INT_S_CRYSTAL_FREQ command to be
able to set these values.
Also change the default APLL setting to 0. It makes no sense to have the
audio clock independent from the video clock, this can lead to audio/video
synchronization problems. Setting this to 0 is also consistent with the old
saa7114.c source and the way the Hauppauge Windows driver sets it.

- implement VIDIOC_INT_S_AUDIO_ROUTING for msp3400 and tvaudio
- use the new command in bttv, pvrusb2 and em28xx.
- remove the now obsolete MSP_SET_MATRIX from msp3400 (yeah!)
- remove the obsolete VIDIOC_S_AUDIO from msp3400.

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.

Video_buf were concerned to allow PCI devices to be used as
video capture devices. This patch extends video_buf features
by virtualizing pci-dependent functions and allowing other
type of devices to use it.
It is still DMA centric, although it may be used also by
devices that emulates scatter/gather behavior or a DMA device

Added a new function that allows printing ioctl arguments.
This makes easier to include debug code under v4l ioctl
handling.
Also fixed some declarations on internal ioctl.

- Moved MSP_SET_MATRIX to v4l2-common.h
- Fix typos and integer overflows in tea5767.c
- Split old freq field into a tv_freq and a radio_freq. Prevents
that a radio tuner is initialized with a tv frequency or vice versa.
- When switching to radio mode initialize the tuner with the last
used radio frequency (this was already done for the TV mode).
As a result of these changes the tuner module now remembers the
last set radio and TV frequencies, which is what you would expect
to happen.
- Move out of range frequencies to the closest valid frequency as per
v4l2 API spec.
- Fix incorrect initial radio frequency (multiplier is 16000, not 16)
- Add boundary check for out of range frequencies.
- Use new flag to check if the order of the CB and freq. depends on
the last set frequency. That is needed for some tuners or you can
get static as a result. The flag is added for those tuners where I know
that the datasheet indicates that this is necessary.
- For this new check use the last set div value, not the last frequency
as radio frequencies are always much higher due to the 16000 multiplier.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
