Our old start of frame detection code wrongly assumes that the sof
marker always lives at the beginning of the frame. At least for the
0c45:602a camera this is not the case. This patch also improves
the framerate from 28 fps to 30 fps with the 0c45:6005 and 0c45:6007

I've a 0c45:6007 camera and it works fine with the gspca_sonixb driver,
so make that handle it instead of the deprecated sn9c102 driver.

The errors were found by checkpatch.pl. Most fixes are:
- remove spaces followed by TAB(s),
- split lines greater than 80 characters,
- move most '{'s from start of line to end of previous line.
(Some '{'s at start of line remain when the '}'s are on the same line)

This patch fixes possible race conditions in queue management with SMP:
when a frame was completed, the irq function tried to use the next frame
buffer. At this time, it was possible that the application on an other
processor updated the frame pointer, making the image to point to a bad
buffer.
The patch contains two main changes:
- the image transfer uses the queue indexes which are protected against
simultaneous memory access,
- the image pointer which is used for image concatenation is only set at
interrupt level.
Some subdrivers which used the image pointer have been updated.

Some sensors only allow controlling the exposure by changing the clockdiv,
which means that exposure takes pretty large jumps (for example when going
from a div of 1 to 2, the exposure doubles). Use 2 different entries in
the controls array for these 2 different types of exposure (always
disabling one), and;
Add a new autogain algorithm for the coarse exposure case, which normally
changes the gain setting, only touching the exposure setting if the desired
luminance cannot be reached with gain, and after an exposure change once more
first tries gain, etc. Thus avoiding exposure changes, and the resulting
oscilation because of the huge steps these exposure controls take.

When using the sonixb driver in a dark room and given that the autoexposure
algorithm starts with a setting most suitable for daylight, the picture
produced by the cam may actually be 100% black leading to a avg_lum value of 0,
so an avg_lum value of 0 does not always signal an exposure settings change
(which it normally does). This patch adds a check for the really black image
case and stops dropping all frames as invalid in this case.

It also removes an usb-id from sn9c102 for one more unsupported bridge

1) Lower the hstart setting for all sensor by 1 so that we generate
(compressed) BGGR data just like sn9c102 does (instead of GBRG data)
2) Add support for raw bayer output in the lowest resolutions (not enough
bandwidth for higher resolutions), this should work with all sensors but
to be sure only enable it for sensors where it has been tested.
