This layout maps to ITU-R BS.2051-3 "Sound System C" and ITU-R BS.1196-8 "Channel
Configuration 14", and it being the first layout with top layer channels, it's
best to use a different scheme to properly convey the presence and amount of said
channels.
The new name will also be a better fit for the additions in the following commits.

Only the collocated_ref of the current frame (i.e. HEVCContext.ref)
is ever used*, so move it to HEVCContext directly after ref.
*: This goes so far that collocated_ref was not even synced across
threads in case of frame-threading.

The vidstab library added support in Nov 2020 for writing/reading
the transforms data in binary in addition to ASCII. The library default
was changed to binary format but no changes were made to the AVfilters
resulting in data file for writing or reading being always opened as text.
This effectively broke the filters.
Option added to vidstabdetect to specify file format and open files in
both filters with the correct attributes.

The is coded as 1920x1080, meant to be rendered at 1440x1080 with cropping,
or 1680x1080 before cropping. Currently, the created DPB is 1440x1080, which results
in the image being decoded incorrectly, as the decoder overwrites output memory.
This commit fixes this.
This eases actual development of the assembly functions, by only
allowing extension instructions within the sections that explicitly
enable them, instead of having all extensions enabled everywhere.

When users zero-init'd the struct, or left it as-is, the encode
queue family matched the graphics queue family, which led it to be
incorrectly logged as being used for encode.
This just improves the logging so this isn't printed anymore.
GetStdHandle is unavailable outside of the desktop API subset.
This didn't use to be a problem with earlier WinSDKs, as kbhit also
used to be available only for desktop apps, and this whole section is
wrapped in #if HAVE_KBHIT. With newer WinSDKs, kbhit() is available also
for non-desktop apps, while GetStdHandle still isn't.

It is unnecessary since the removal of non-thread-safe callbacks
in e0786a8eeb. Since then, the
AVCodecContext has only been used as logcontext.
Removing ff_thread_release_buffer() allowed to remove AVCodecContext*
parameters from several other functions (not only unref functions,
but also e.g. ff_h264_ref_picture() which calls ff_h264_unref_picture()
on error).

At various points through the function librsvg_decode_frame, errors are
returned from immediately without deallocating any allocated structs.
This patch both fixes those leaks, and also fixes the use of functions
that are deprecated since librsvg version 2.52.0. The older calls are
still used, guarded by #ifdefs while the newer replacements are used if
librsvg >= 2.52.0. One of the deprecated functions is used as a check
for the configure shell script, so it was replaced with a different
function.

libavcodec/aarch64/vc1dsp_neon.S is skipped here, as it intentionally
uses a layered indentation style to visually show how different
unrolled/interleaved phases fit together.

Favour left aligned columns over right aligned columns.
In principle either style should be ok, but some of the cases
easily lead to incorrect indentation in the surrounding code (see
a couple of cases fixed up in the preceding patch), and show up in
automatic indentation correction attempts.

Some functions have slightly different indentation styles; try
to match the surrounding code.

Fix rendering of int values within a side data element, which was
broken since commit d2d3a83ad9, where the side data element was
correctly marked as a variable fields element. Logic to render a
string variable was implemented already, but it was not implemented
for the int fields path, which was enabled by that commit.
Also, code and schema is changed in order to account for multiple
variable-fields elements - such as side data, contained within the
same parent. Previously it was assumed that a single variable-fields
element was contained within the parent, which was the case for tags,
but is not the case for side-data.
Previously data was rendered as:
<side_data_list>
<side_data side_data_type="CPB properties" max_bitrate="0" min_bitrate="0" avg_bitrate="0" buffer_size="327680" vbv_delay="-1"/>
</side_data_list>
Now as:
<side_data_list>
<side_data type="CPB properties">
<side_datum key="side_data_type" value="CPB properties"/>
<side_datum key="max_bitrate" value="0"/>
<side_datum key="min_bitrate" value="0"/>
<side_datum key="avg_bitrate" value="0"/>
<side_datum key="buffer_size" value="49152"/>
<side_datum key="vbv_delay" value="-1"/>
</side_data>
</side_data_list>
Variable-fields elements are rendered as a containing element wrapping
generic key/values elements, enabling use of strict XML schema.

This logic only covers the case of yuv420p. Extend this logic to cover
*all* vertically subsampled YUV formats, which require the same
interlaced scaling logic.
Fortunately, we can get away with re-using the same code for both JPEG
and MPEG range YUV, because the only difference here is the horizontal
alignment. (Which I omit touching for now, to avoid introducing possibly
unintended changes in default behavior)
