64ecb78b71 vdpau: do not use buggy HEVC support by default 
NVIDIA broke its own API when using VDPAU decoding. If you retrieve the
decoded YUV data, or if you map the surfaces with GL interop, the result
are interlacing artifacts. The only way to get non-broken data is by
using the vdpau video mixer to convert it to RGB. There is no way to
block the non-working operations in a reasonable way (a VdpVideoSurface
has to support all operations).

NVIDIA refuses to fix this issue (they "fixed" it by making it work with
the video mixer, but the rest is still broken). There is no sign of that
changing.

Do not use HEVC by default with the generic hwaccle API. Detect whether
it's the NVIDIA native implementation, and exit with an error. (The same
thing work with the MESA implementation.)

As an escape hatch and to allow applications to use the decoder if they
really want to (perhaps because they make sure to explicitly use the
video mixer), reuse AV_HWACCEL_FLAG_ALLOW_PROFILE_MISMATCH to disable
this check.

Once NVIDIA fixes the bug, working driver versions could be detected,
and it could be allowed again.

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.

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.

Merges Libav commit 3fdf50f9e8.
