!(c->pix_fmt != AV_PIX_FMT_NONE || c->got_format_from_params)
equals
(c->pix_fmt == AV_PIX_FMT_NONE) && !c->got_format_from_params
1. When (c->pix_fmt == AV_PIX_FMT_NONE) is true, got_format_from_params is
always false, the flag doesn't contribute to the result.
2. When the first part is false, the second part doesn't matter, the flag
doesn't contribute to the result.
The result only depends on c->pix_fmt.
It performs HDR(High Dynamic Range) to SDR(Standard Dynamic Range) conversion
with tone-mapping. It only supports HDR10 as input temporarily.
An example command to use this filter with vaapi codecs:
FFMPEG -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi \
-i INPUT -vf 'tonemap_vaapi=format=p010' -c:v hevc_vaapi -profile 2 OUTPUT

The documentation still mentions numerical constants in addition to textual
ones. It is also wrong to use distinct modes as flags and it disallows us to
actually use the flags field for real flags in the future.

Adjustment of evaluated values shifted to ff_adjust_scale_dimensions
Shifted code for force_original_aspect_ratio and force_divisble_by from
vf_scale so it is now available for scale_cuda, scale_npp and
scale_vaapi as well.
Width and height expressions can refer to each other. Width is
evaluated twice to allow for reference to output height. So we
should not error out upon failure of first evaluation of width.
The unsharp filter uses an array of arrays of uint32_t, each of which is
separately allocated. These arrays also need to freed separately; but
before doing so, one needs to check whether the array of arrays has
actually been allocated, otherwise one would dereference a NULL pointer.
This fixes#8408.
Furthermore, the array of arrays needs to be zero-initialized so that
no uninitialized pointer will be freed in case an allocation of one of
the individual arrays fails.
