- support interlacing with VIDIOC_G_FMT
- set V4L2_CAP_TUNER if driver implements the set_tuner/get_tuner
callbacks
- set V4L2_CAP_AUDIO if driver implements the set_audio/get_audio/enum_audio
callbacks
- add support for the following ioctls: VIDIOC_ENUMSTD, VIDIOC_G_STD,
VIDIOC_S_STD, VIDIOC_ENUMINPUT, VIDIOC_G_INPUT, VIDIOC_S_INPUT,
VIDIOC_ENUMAUDIO, VIDIOC_G_AUDIO, VIDIOC_S_AUDIO, VIDIOC_G_TUNER,
VIDIOC_S_TUNER, VIDIOC_G_FREQUENCY, VIDIOC_S_FREQUENCY
- in video_submit_payload(), fix support for signaling sample complete
using frame numbers
- new optional callbacks for drivers: enum_standard, get_standard,
set_standard, enum_input, get_input, set_input, enum_audio, get_audio,
set_audio, get_tuner, set_tuner, get_frequency, set_frequency
for drivers that don't provide enum_standard, get_standard, set_standard,
enum_input, get_input and set_input, the original stub implementations are
provided
