Add support for 32-bit ioctls with v4l-subdev device nodes.
Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.
We keep forgetting to add new ioctls, so this is a more robust solution.
In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.

These ioctls are no longer used by any drivers, so remove them.

This patch adds extension to V4L2 api. A new ioctl VIDIOC_EXPBUF is added. The
ioctl is used to export an mmap buffer as a DMABUF file descriptor.

Adds DMABUF memory type to v4l framework. Also adds the related file
descriptor in v4l2_plane and v4l2_buffer.

This buffer type isn't used at all, and since it is effectively undefined
what it should do it is deprecated. The define still exists, but any
internal support for such buffers is removed.
The decisions to deprecate this was taken during the 2012 Media Workshop.

Currently, the v4l2 core is mixed together with other non-core drivers.
Move them into a separate directory.
