Don't blindly copy all bytes in extradata past ChannelMappingFamily. Instead
check if ChannelMappingFamily is not 0 and then only write the correct amount
of bytes from ChannelMappingTable, as defined in the spec[1].
Should fix ticket #9190.

map_type 0 is always 19 bytes, whereas map_type 1 and 255 are 21 + channel
count bytes.

av_vorbis_parse_init() doesn't return an error code which is a slight
problem in libvorbisenc.c. Fix this by making the internal
initialization function behind av_vorbis_parse_init() available. This
also avoids allocations and frees (for users inside of this inside
libavcodec).

The vorbis_comment struct used to during codec initialization
would leak in case an error happened after its initialization
(e.g. if the allocation of extradata failed). This has been fixed.
Given that said struct is only used when writing the header, it has
also been moved from the context.

ffio_fill() is used when initially writing unknown length elements;
yet it can happen that the amount of bytes written by it is zero in
which case it is of course unnecessary to ever call it. Whether it is
possible to know this during compiletime depends upon how aggressively
the compiler inlines

This would only make a difference in case the first attempt to
initialize the encoder failed and the second succeeded. The only
reason I can think of for this to happen is that the options (in
particular the codec whitelist) are not used for the second try
and that obviously implies that we should

Some files currently rely on libavutil/cpu.h to include it for them;
yet said file won't use include it any more after the currently
deprecated functions are removed, so include attributes.h directly.

current code:
pred16x16_top_dc_10_c: 106.093.2
pred16x16_top_dc_10_neon:87.777.5
ld1, add, addv variant:

Inlined a few comments for ff_pred16x16_top_dc_neon_10, other are similar.

Attempts to utilize the TTML cell resolution as a mapping to the
reference resolution, and maps font size to cell size. Additionally
sets the display and text alignment according to the ASS alignment
number.

This way the encoder may pass on the following values to the muxer:
1) Additional root "tt" element attributes, such as the subtitle
canvas reference size.
2) Anything before the body element of the document, such as regions
in the head element, which can configure
Now sets alignment, font size, font family and the region's position
and size according to the ASS styles passed to the encoder. Regions are
relatively important in TTML, since the spec-defined default region is in
raster location (similar to the default with HTML) - it starts from the
top left
