Hi folks,

This patch adds a new signal in V4L2VideoDevice that not only reports a
completed buffer, but also its request fd. This helps save some
unnecessary mappings from buffers to requests.

We might also consider removing the signal bufferReady, if we migrate all
usages to the new signal.

This passes gitlab pipeline:

BR,
