This patch enables paletteuse to identify the transparency in incoming
video and tag transparent pixels on outgoing video with the correct
index from the palette.
This requires tracking the transparency index in the palette,
establishing an alpha threshold below which a pixel is considered
transparent and above which the pixel is considered opaque, and
additional changes to track the alpha value throughout the conversion
process.
This change is a partial fix for https://trac.ffmpeg.org/ticket/4443
However, animated GIFs are still output incorrectly due to a bug
in gif optimization which does not correctly handle transparency.

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.
