V4L/DVB (5644): Usbvision: video_ioctl2 conversion 

The ioctl entry point, a big switch/case, is splitted in little 
functions. 

These functions are set as callbacks for the video_ioctl2 video4linux 
facility.

This improves the driver memory consumption and enables the v4l1 
compatibility as a side effect.
