Having a framerate divisor of 3 is not really necesarry and leads to
various troubles (frames going missing, compression issues) when allowed.

The illuminator controls should only be available to the user for the Intel
Play QX3 microscope. The implementation to inhibit the controls is intended to
be consistent with the other gspca driver implementations.

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.

The image pointer and its length are now in the main structure instead
of in the frame buffer. They are updated on application vidioc_qbuf and
in the URB interrupt function when ending an image.
