Hook in libklvanc and use it for output of EIA-708 captions over
SDI.  The bulk of this patch is just general support for ancillary
data for the Decklink SDI module - the real work for construction
of the EIA-708 CDP and VANC line construction is done by libklvanc.

Libklvanc can be found at: https://github.com/stoth68000/libklvanc

When encoding to V210, make sure the CC side data makes it through
in the resulting AVPacket.  This is needed so the decklink output
module can put out captions when in 10-bit mode.

ISOBMFF does not allow AudioSampleEntryV1 in stsd version 0, so
assume the descriptor format is QTFF SoundDescriptionV1. ISOBMFF does
not define a version 2.

This fixes audio decoding for some MP4 files generated with Apple
tools. The additional fields present in SoundDescriptionV1/V2 need to
be read in order to correctly read additional boxes that contain
information required for decoding the stream.

Fixes #7376.

Simplify macro TRANSPOSE_4H in mmiutils.h and add TRANSPOSE_8B as a common macro.

Optimize vp8 loop filter with mmi, four functions optimized:
1. ff_vp8_h_loop_filter8uv_mmi.
2. ff_vp8_v_loop_filter8uv_mmi.
3. ff_vp8_h_loop_filter16_mmi.
4. ff_vp8_v_loop_filter16_mmi.

Vp8 decoding speed improved about 50%(from 73fps to 110fps, Tested on loongson 3A3000).
