V4L camera control enhancements

Hello,

this is a second iteration of my camera control patches. Besides the 
previous ones, it also includes the scene mode and 3A lock controls.
The 3A lock bitmask control allows to lock/unlock automatic exposure, 
white balance and focus adjustments. It is useful for pre-focus 
for instance.

I had been a little hesitant about introducing the scene mode control, 
however it is really needed, since some sensors with more advanced ISPs
or the ISPs inside host processors running their own firmware support 
the scene modes through a single configuration register.

The controls included in this series have been successfully used in 
the Samsung Android kernels for several years now. I'd like to extend
the V4L2 API to include at least most of the basic functionality 
available there.

Changes since v1 (implicit):
 - the V4L2_CID_AUTO_FOCUS_FACE_PRIORITY control merged with
   V4L2_CID_AUTO_FOCUS_FACE_AREA,
 - many minor documentation corrections,
 - removed "08/23 V4L: camera control class..." patch, which got 
   accidentally added at v1,
 - added V4L2_CID_SCENE_MODE and V4L2_CID_3A_LOCK controls,
 - added vivi patch for testing.

Any comments are welcome. I'd like to get this patch set merged for v3.5.
Maybe except the 3 focus related patches, since I'm not entirely happy 
with those API additions. I'll try to seek some time to complete those 
too though.

The patches will be also available in few hours at:
