Scott Theisen 9fb806fa57 avcodec: add AV_CODEC_ID_IVTV_VBI ...

IVTV, a Linux driver for TV tuners, and V4L2 utilize
a coding named after IVTV to carry sliced VBI data
in MPEG streams produced by tuner cards with
VBI capture capability and an MPEG-2 encoder SoC.

IVTV or V4L2 driver will transport the coded data into a
MPEG-PS private stream ("IVTV") that can be captured
from the card alongside the video/audio.

The data could include:
EIA-608, Teletext, WSS (PAL widescreen signaling),
or VPS (PAL VCR signaling).
