benched. Introduced in cc679054c7.

So far, AV_READ_TIME would return the cycle counter. This posed two
problems:
1) On recent systems, it would just raise an illegal instruction
exception. Indeed RDCYCLE is blocked in user space to ward off some
side channel attacks. In particular, this would cause the random
number generator to crash.
2) It does not match the x86 behaviour and the apparent original intent
of AV_READ_TIME in the functional code base (outside test cases).
So this replaces the cycle counter with the time counter. The unit is
a platform-dependent constant fraction of time, and the value should be
stable across harts (RISC-V lingo for physical CPU thread).
It is currently probably not possible for it to be negative as
the needed 2Mb input buf size is not achievable. But it is more
robust to check for it too.
If it would become negative than code like
s->samples[0][n] = s->samples[0][s->nb_samples + n];
would crash

The fate-run.sh shell script exports LC_ALL=C before invoking the
test executables; this is probably done for consistency.
When executing Windows binaries with Wine, it normally handles
UTF-8 command line parameters just fine - but with LC_ALL set to
C, it treats them as plain ASCII.
As the unicode command line parameters wasn't the main thing
being tested here, just convert them to plain ASCII, for
portability. This fixes the test for all test configurations that
use Wine.

ddc1cd5cdd defined WIN32_LEAN_AND_MEAN
globally, which makes for much fewer transitive includes from
windows.h. With that define, CoTaskMemFree no longer gets
implicitly declared by just including windows.h, but one has to
include the right header objbase.h too.
That commit caused ole32 to no longer get detected, which caused
dxva2 to no longer be enabled. This gets fixed by this patch.

This commit fixes bug #10495
The code had several bugs related to post-loop compensation code:
- test assembly instruction performs bitwise AND operation and
generate flags used by jz branch instruction. Wrong test condition
leads to incorrect branching
- Incorrect compensation code for some branches

Currently, create_pnext is only used if an applicable external memory
extension is enabled. This will usually the case when used from the command
line, but may not be when the Vulkan context is created manually.
For images used in video decoding, create_pnext contains the video profile
list, which is mandatory.[1] This fixes a GPU crash when using RADV.

C++ doesn't support designated initializers until C++20. We have
a bunch of pre-defined channel layouts, the gains to make them
usable in C++ exceed the losses.
Bump minor version so C++ project can check before use these defines.
Also initialize .opaque field explicitly to reduce warning in C++.

By default the OpenEXR decoder outputs linear light pixel data by
applying a gamma=1.0 transfer (i.e. a no-op). When it does so, it
should tag the data as linear so color-managed filters or other tools
can work with it correctly.

If user doesn't set framerate when he creates a filter, the filter uses
default framerate {0, 1}. This causes error when setting timebase to
1/framerate. Now change it to pass inlink->time_base to outlink when
framerate is not set.

bzlib.h to parse as nonsense, due to an instance of #define char small

because the flv specification said the video frametype
should use value range from 0x00 to 0x70,
so use 0xF0 have no problem before support enhanced flv,
but the 0xF0 will get incorrect result after support enhanced flv,
so should set the video frametype mask 0x70 to make it correct now.
