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.

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.
Fix trac issue:

Always use the functionality of the latter, which makes more sense as it
avoids losing keyframes due to vsync code dropping frames.
Deprecate the 'source_no_drop' value, as it is now redundant.
This is no longer needed as the side data is available for decoders in the
AVCodecContext.
The tests affected reflect the removal of useless CPB and Stereo 3D side
data in packets.

The changed references for fate-hevc-dv-rpu fate-mov-zombie happen because,
unlike ffmpeg and ffplay, ffprobe never injected packet side data, so the
display matrix side data at the container level is now present in the output
frames.

Also, avoid spurious end-of-line after side data entries, and improve
rendering of compact output, by adding an indication of the side data
type for each entry.
Also fixes issue:
http://trac.ffmpeg.org/ticket/9266
In this case any timestamps are guessed by compute_pkt_fields() in
libavformat. Since we are decoding the stream, we have more accurate
information from the decoder and do not need any guesses.
Eliminates spurious PTS gaps in a number of FATE tests.
Also avoids dropping the majority of frames in fate-dirac*
We have to write an explicit BlockDuration element (and use
a BlockGroup instead of a SimpleBlock) in case the Track
has a DefaultDuration that is inconsistent with the duration
of the packet.
The matroska-h264-remux test uses a file with coded fields
where the duration of a Block is the duration of a field,
not of a frame, therefore this patch writes said BlockDuration
elements.
(When using a BlockGroup, one has to add ReferenceBlock elements
to distinguish keyframes from non-keyframes. Unfortunately,
the AV1 codec mapping [1] requires us to reference all references
and to really use the real references, which requires a lot of
effort for basically no gain. When BlockGroups are used with AV1,
the created files are most likely invalid, both before and after
this patch, but this patch makes this more likely to happen.)

They were replaced by TX from libavutil; the tremendous work
to get to this point (both creating TX as well as porting
the users of the components removed in this commit) was
completely performed by Lynne alone.
Removing the subsystems from configure may break some command lines,
because the --disable-fft etc. options are no longer recognized.

From the documentation of GNU awk [1]:
"In most awk implementations, including gawk, rand() starts generating
numbers from the same starting number, or seed, each time you run awk.45
Thus, a program generates the same results each time you run it. The
numbers are random within one awk run but predictable from run to run.
This is convenient for debugging, but if you want a program to do
different things each time it is used, you must change the seed to a
value that is different in each run. To do this, use srand()."
This commit does exactly this.

for S8 we continue to use S16 as it should have enough precision
Fate is adjusted so bitexactness is maintained between mips/arm/x86
if more tests became bit-inexact on some platform, the same change
can be done to them
The use of higher precision and float intermediates inevitably
leads to more differences between platforms.

It is badly named (should have been -top_field_first, or at least -tff),
underdocumented and underspecified, and (most importantly) entirely
redundant with the setfield filter.
Not every user of idctdsp.h wants to initialize an IDCTDSPContext;
e.g. the proresdsp only uses ff_init_scantable_permutation()
and the IDCT permutation enum; similarly for cavsdsp and wmv2dsp.
Using a forward declaration here avoids an avcodec.h dependency
in the relevant files.

And remove the AVOID_PROBING flag, given it's the last av1 decoder to be tested
either way.
This fixes a regression introduced in 1652f2492f,
where even if forcing the native av1 decoder, if another decoder was present,
like libdav1d or libaom-av1, they'd be used for probing and some fate tests
would have different results.

This is the very last user of any lavc transform code.
This also *corrects* wmavoice decoding, as the previous DCT/DST
transforms were incorrect, bringing it closer to Microsoft's
own wmavoice decoder.
Adds a fate test for the jpegxl_anim demuxer, that should allow testing

that two of the test cases are not animated, in order to help sort out

When muxing, the AVStreams' side-data is typically set
by the caller before avformat_write_header();
it is not documented to be else. Yet the Matroska muxer
added an AVStereo3D side data if certain metadata
was present:
Since commit 4d686fb721
(adding support for AVStereo3D stream side-data),
the Matroska muxer checked certain stream tags that
contain Matroska's StereoMode and (if they are present)
converted this value into an AVStereo3D struct that
gets attached to the AVStream (reusing a function from
the demuxer). Afterwards the AVStereo3D side data struct
(whether it has just been added by the muxer or not) gets
parsed and converted back into a Matroska StereoMode.
Besides being an API violation this change broke
StereoMode values without a corresponding AVStereo3D
(namely the anaglyph ones).
This commit fixes this: A StereoMode given via tags
is now used-as-is; if no such tag exists and an AVStereo3D
side data exists, it is converted into the corresponding
StereoMode (if possible). This approach also fixes
handling of the anaglyph ones; the changes to the
matroska-stereo_mode are due to this.
The new STEREOMODE_STEREO3D_MAPPING has been put to
good use for this.
