Use class confidence instead of box_score to filt boxes, which is more
accurate. Class confidence is obtained by multiplying class probability
distribution and box_score.

For detect and classify output, width and height make no sence, so
change width, height to dims to represent the shape of tensor. Use
layout and dims to get width, height and channel.

Now when using openvino backend, user doesn't need to set input/output
names in command line. Model ports will be automatically detected.
For example:
ffmpeg -i input.png -vf \
dnn_detect=dnn_backend=openvino:model=model.xml:input=image:\
output=detection_out -y output.png
can be simplified to:
ffmpeg -i input.png -vf dnn_detect=dnn_backend=openvino:model=model.xml\
-y output.png

nal->skipped_bytes_pos contains the positions of errors relative to the
start of the slice header, whereas the position they were tested against
is relative to the start of the slice data, i.e. one byte after the end
of the slice header.
Patch fixes this by storing the size of the slice header in H266RawSlice
and adding it to the position given by the GetBitContext before
comparing to skipped_bytes_pos. This fixes AVERROR_INVALIDDATAs for
various valid bitstreams, such as the LMCS_B_Dolby_2 conformance
bitstream.

Fixes#10759.
It can happen in H.264, MPEG2, VC1 that the current frame resource
memory is already in ref_resource. For example, for a interlaced frame,
the same curr memory is passed twice. For the second time it could possibly
reference itself. When this happens the curr is already given an index and
in ref_resources. When the reference frame index is required, we should check
the existance in the ref_resources first before assigning a new index for it.

This file has been exported since our minimum required version (0.7.0),
but it wasn't documented. Instead it was transitively included by
<jxl/decode.h> (but not jxl/encode.h), which ffmpeg relied on.
libjxl broke its API in libjxl/libjxl@66b959239355aef5255 by removing
the transitive include of version.h, and they do not plan on adding
it back. Instead they are choosing to leave the API backwards-
incompatible with downstream callers written for some fairly recent
versions of their API.
As a result, we include <jxl/version.h> to continue to build against
more recent versions of libjxl. The version macros removed are also
present in that file, so we no longer need to redefine them.

VVC specifies << as arithmetic left shift, i.e. x << y is equivalent to
x * pow2(y). C's << on the other hand has UB if x is negative. This
patch removes all UB resulting from this, mostly by replacing x << y
with x * (1 << y), but there are also a couple places where the OOP was
changed instead.
