ff2d21a58c hevcdec: properly export some side data with frame threading 
I noticed this with mastering display data. If frame threading is
enabled, this side data is exported only for some frames. It turns out
it's not properly propagated to the worker threads.

I didn't touch A53 captions, because that involves memory allocation and
freeing the data as side data is exported.

Micro bump so that API users can detect the bug fix.

3426832ac3 hevc: Add support for alternative transfer characterics SEI 
The use of this SEI is for backward compatibility in HLG HDR systems:
older devices that cannot interpret the "arib-std-b67" transfer will
get the compatible transfer (usually bt709 or bt2020) from the VUI,
while newer devices that can interpret HDR will read the SEI and use
its value instead.

e4a27e2f2d lavc/arm: fix lack of precision in ff_ps_stereo_interpolate_neon 
The code originally pre-multiply by 2 the steps, causing the running sum
of the h factors to drift away due to the lack of precision. It quickly
causes an inaccuracy > 0.01.

I tried diverse approaches such as multiply by 2.0 (instead of adding
the value itself) without success.

I'm unable to bench the impact of this change, feel free to compare.

This commit fixes the incoming aacpsdsp tests.

Following is an alternative simplified function (matching the incoming
AArch64 code) that may be used:

d14179e3d4 hwframe: Allow hwaccel frame allocators to align surface sizes 
Hardware accelerated decoding generally uses AVHWFramesContext for pool
allocation of hardware surfaces. These are setup to allocate surfaces
aligned to hardware and hwaccel API requirements. Due to the
architecture, av_hwframe_get_buffer() will return AVFrames with
the dimensions set to the aligned sizes.

This causes some decoders (like hevc) return these aligned size as
final frame size, instead of cropping them to the video's actual
dimensions. To make sure this doesn't happen, crop the frame to the
size the decoder expects when ff_get_buffer() is called.

8d7fdba7b8 dxva: support DXGI_FORMAT_420_OPAQUE decoding 
Some devices (some phones, apparently) will support only this opaque
format. Of course this won't work with CLI, because copying data
directly is not supported.

Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does
not support this mode, even if it's the only supported mode. But since
opaque surfaces are generally less useful, that's probably ok.
