libcamera: pipeline: vivid: Buffer handling and stream control
We can now add buffer management, and connect up our bufferReady signal to a callback. Note that we provide the ability to export buffers from our capture device (data->video_) using the exportBuffers() functionality from the V4L2VideoDevice which allows a FrameBufferAllocater to obtain buffers from this device. When buffers are obtained through the exportFrameBuffers API, they are orphaned and left unassociated with the device, and must be reimported at start() time anyway. This allows the same interface to be used whether internal buffers, or external buffers are used for the stream. When a buffer completes, we call the buffer completion handler on the pipeline handler, and because we have only a single stream, we can also immediately complete the request.
