The symbol prefix check would incorrectly detect a bogus prefix in
circumstances where sanitizers instrument the build, like when
configuring with the clang-asan toolchain where it would detect the
prefix as __odr_asan_gen_, which is obviously wrong.
To fix this, adjust the prefix detection to only detect a
one-character prefix, which is the only case that matters
anywhere right now.

This commit adds the first Vulkan hardware encoder.
Currently, P, and **B**-frames are supported. This marks the
first implementation to support both.
The encoder has feature-parity with VAAPI.

This commit adds the common Vulkan video encoding framework.
It makes full use of the asynchronous features of our new common
hardware encoding code, and of Vulkan.
The code is able to handle anything from H264 to AV1 and MJPEG.

configure use "-Wl,-framework,foo" and "-framework foo" to specify
dependencies on Apple frameworks. These two styles essentially do
the same thing when build ffmpeg. However, they do make difference
when generate pkg-config files. Some tools interact with pkg-config
cannot handle "-Wl,-framework,foo" in Libs field, e.g., cmake with
pkg_check_modules.

Should make strict compilers happy.
Also, make AV_COPY128 use integer operations while at it. Removing the
inclusion of immintrin.h ensures a lot less intrinsic related headers are
included as well, which fixes a clash of defines with some Clang versions.

When called inside a loop, the inline asm version results in one pxor
unnecessarely emitted per iteration, as the contents of the __asm__() block are
opaque to the compiler's instruction scheduler.
This is not the case with intrinsics, where pxor will be emitted once with any
half decent compiler.
This also has the benefit of removing any SSE -> AVX penalty that may happen
when the compiler emits VEX encoded instructions.

Currently, any unrecognised platform is treated as 32-bit. This should
detect *most* 64-bit platforms, namely LP64 and LLP64 ones.
Unfortunately this will not work for ILP32 ABIs on 64-bit ISAs, but
still better than nothing.

The vendor has long since switched to Arm, with the last product
reaching their official end-of-life over 11 years ago. Linux support for
the ISA was dropped 7 years ago. More importantly, this architecture was
never supported by upstream GCC, and the vendor fork is stuck at version
4.2, which FFmpeg no longer supports (as per C11 requirement).
Presumably, this is still the case given the lack of vendor support.
Indeed all of the code being removed here consisted of inline assembler
scalar optimisations. A sane C compiler should be able to perform those
automatically nowadays (with the sole exception of fast CLZ detection),
but this is moot as this architecture is evidently dead.

Support for SuperH was dropped over a decade ago. There no longer is any

Introduced in 1992, the Alpha was a 64-bit RISC processor designed to replace the
VAX CISC machines sold by Digital Equipment Corporation.
After Digital was acquired by Compaq in 1998 -- who themselves would be later
purchased by Hewlett-Packard, the architecture was phased out over the following decade.
It became effectively defunct in 2007, the last publically available processor being the Alpha 21364.
FFmpeg has not added any DSP code for this architecture since lowres2 was introduced in 2012,
and it is more than unlikely someone still wishes to maintain it.
Remove the DSP and support code.
The DNN filters are useless without a backend.
This will also "fix" Coverity issues #1598288 and #1601718.

Not all C run-times support this, and even then, it will be a while
before distributions provide recent enough versions thereof.
Since this is a trivial system call wrapper, we might just as well call
the corresponding kernel system call directly where the C run-time lacks
support but the kernel headers are new enough (as is the case on Debian
Unstable at the time of writing). In doing so, we need to add a few more
guards as the first suitable kernel (headers) release did not expose the
V, Zba and Zbb extensions.

This adds the Linux-specific function call to detect CPU features. Unlike
the more portable auxillary vector, this supports extensions other than
single lettered ones. At this point, FFmpeg already needs this to detect
Zba and Zbb at run-time, and probably will need it for Zvbb in the near
future.
