Guennadi Liakhovetski 2150158b31 [media] V4L: add two new ioctl()s for multi-size videobuffer management ...

A possibility to preallocate and initialise buffers of different sizes
in V4L2 is required for an efficient implementation of a snapshot
mode. This patch adds two new ioctl()s: VIDIOC_CREATE_BUFS and
VIDIOC_PREPARE_BUF and defines respective data structures.
