Browse source 
Handle the response sent by the firmware, when a source change is
detected. Read the subscribed parameter to get the changed values. Raise
the source change event to the client and update the instance sub-state.

Mark the last buffer from before the source change with the
V4L2_BUF_FLAG_LAST flag and return to the client.
