* commit '50a1c66cf6ab7eb683daaa9e2da3869fa3a54609':
ac3_parser: add a public function for parsing the data required by the demuxer
avpriv_ac3_parse_header() is left in place but without the
GetBitContext parameter, as the mov muxer requires a lot more fields
than just bitstream_id and frame_size from the AC3HeaderInfo struct.

If the metadata packet is corrupted, flv_read_metabody can accidentally
read past the start of the next packet. If the start of the next packet
had been flushed out of the IO buffer, we would be unable to seek to
the right position (on a nonseekable stream).
Prefer to clearly error out instead of silently trying to read from a
desynced stream which will only be interpreted as garbage.

According to EBU tech 3285 supplement 3 the dwPosPeakOfPeaks field
should contain the absolute position to the maximum audio sample value,
but the current implementation writes the relative peak frame index
instead.
Fix the issue by writing the "unknown" value (-1) for now until the
feature is implemented correctly.

This patch uses dithering in DITHER_COPY macro only if
it was not used option '-sws_dither none'.
With option '-sws_dither none' it uses downshift.
For human eye dithering is OK, for video codecs not necessarily.
If user don't want to use dithering, we should respect that.

Technically _tzcnt* intrinsics are only available when the BMI
instruction set is present. However the instruction encoding
degrades to "rep bsf" on older processors.
Clang for Windows debatably restricts the _tzcnt* instrinics behind
the __BMI__ architecture define, so check for its presence or
exclude the usage of these intrinics when clang is present.
