c64da19bbc dxva: DXVA2_ModeHEVC_VLD_Main10 does not support Main 
This mode apparently does not support decoding of HEVC Main (8 bit).
With D3D11 and Intel drivers on Windows 10 I get green corruption, while
using DXVA2_ModeHEVC_VLD_Main works.

Replicates the logic used in the wrap_hw_buffer path to wrap_sw_buffer

Fixes decoding issues observed on AMLogic devices with
OMX.amlogic.mpeg2.decoder.awesome, where the decoder would spit out a
constant stream of "mPtsRecoveryCount" errors and decoded frames were
returned in the incorrect order.

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.
