6cd97cd797 lavc/ac3dsp: R-V V sum_square_butterfly_float 
As we do not need to widen accumulators to 64 bits, we effectively get
double capacity for unrolling compared to the integer function. This
explains the slightly better performance gains.

ac3_sum_square_bufferfly_float_c:       65.2
ac3_sum_square_bufferfly_float_rvv_f32: 12.2

c3ca90a92e avcodec/x86/vp3dsp_init: Set correct function pointer, fix crash 
Regression since fd17218558;
triggered by vp4/KTkvw8dg1J8.avi in the FATE suite, but not
when running fate as this code is not used when the bitexact
flag is set.

Bisecting done by ami_stuff, patch from user Mika Fischer
in ticket #10027 (which this commit fixes).

9fb3d640fb avcodec/av1dec: Always set ret before goto end 
Before 0f8763fbea, av1_frame_ref()
and update_reference_list() could fail and therefore needed to
be checked, which incidentally set ret. This is no longer happening,
leading to a potential use of an uninitialized value which is
also the subject of Coverity ticket #1596605.

Fix this by always setting ret before goto end; do not return
some random ancient value.

Ubuntu 20.04 and Leap 15.0.

Allows cleaning up the file substantially. In particular, this is
motivated by the desire to stop relying on init_static_data.

opusdsp: add ability to modify deemphasis constant

The code to apply it is identical, it's still just a
simple IIR low-pass filter. This commit makes it possible
to use alternative constants.

9d675bb60d avcodec/nvenc: add high bit depth encoding for HEVC 
Adding 10-bit encoding support for HEVC if the input is 8-bit. In
case of 8-bit input content, NVENC performs an internal CUDA 8 to
10-bit conversion of the input prior to encoding. Currently, only
AV1 supports encoding 8-bit content as 10-bit.
