Our v4l2_queue_buffer and v4l2_dequeue_buffer functions give us a
wrapper around the raw V4L2 ioctls with a wrapper struct video_buffer
around the raw struct v4l2_buffer. The problem is that the
video_buffer's mem field is never populated, so there's no way to access
the mem that the buffer refers to given only the buffer.
Populate the video_buffer's mem field at v4l2_dequeue_buffer based on
the dequeued v4l2 buf's index.

videobuf2 relies on the sizeimage field to calculate buffer size
when the format is MJPEG, because the bytes-per-line calculation
is missing. Fill in that field as part of v4l2_set_format() so the
API works correctly.

We would like to be able to set the frame rate of video sources. This
patch adds such a function for v4l2-based video sources to use.

Split the project into a UVC gadget library and a test application. To
avoid rolling out a custom build system, switch to CMake.
