    swscale/graph: pass per-pass image pointers to setup()
This behavior had no real justification and was just incredibly confusing,
since the in/out pointers passet to setup() did not match those passed to
run(), all for what is arguably an exception anyways (the palette setup).

    tests/checkasm: increase number of runs in between measurements
Sometimes, when measuring very small functions, rdtsc is not accurate enough
to get a reliable measurement. This increases the number of runs inside the
inner loop from 4 to 32, which should help a lot. Less important when using
the more precise linux-perf API, but still useful.

There should be no user-visible change since the number of runs is adjusted
to keep the total time spent measuring the same.

    tests/checkasm: generalize DEF_CHECKASM_CHECK_FUNC to floats
We split the standard macro into its body (implementation) and declaration,
and use a macro argument in place of the raw `memcmp` call, with the major
difference that we now take the number of pixels to compare instead of the
number of bytes (to match the signature of float_near_ulp_array).

    swscale/ops: add dispatch layer
This handles the low-level execution of an op list, and integration into
the SwsGraph infrastructure. To handle frames with insufficient padding in
the stride (or a width smaller than one block size), we use a fallback loop
that pads the last column of pixels using `memcpy` into an appropriately
sized buffer.

    swscale/ops_backend: add reference backend basend on C templates
This will serve as a reference for the SIMD backends to come. That said,
with auto-vectorization enabled, the performance of this is not atrocious.
It easily beats the old C code and sometimes even the old SIMD.

In theory, we can dramatically speed it up by using GCC vectors instead of
arrays, but the performance gains from this are too dependent on exact GCC
versions and flags, so it practice it's not a substitute for a SIMD
implementation.

    swscale/x86: add SIMD backend
This covers most 8-bit and 16-bit ops, and some 32-bit ops. It also covers all
floating point operations. While this is not yet 100% coverage, it's good
enough for the vast majority of formats out there.

Of special note is the packed shuffle fast path, which uses pshufb at vector
sizes up to AVX512.

    tests/checkasm: add checkasm tests for swscale ops
Because of the lack of an external ABI on low-level kernels, we cannot
directly test internal functions. Instead, we construct a minimal op chain
consisting of a read, the op to be tested, and a write.

The bigger complication arises from the fact that the backend may generate
arbitrary internal state that needs to be passed back to the implementation,
which means we cannot directly call `func_ref` on the generated chain. To get
around this, always compile the op chain twice - once using the backend to be
tested, and once using the reference C backend.

The actual entry point may also just be a shared wrapper, so we need to
be very careful to run checkasm_check_func() on a pseudo-pointer that will
actually be unique for each combination of backend and active CPU flags.

    swscale/format: add new format decode/encode logic
This patch adds format handling code for the new operations. This entails
fully decoding a format to standardized RGB, and the inverse.

Handling it this way means we can always guarantee that a conversion path
exists from A to B without having to explicitly cover logic for each path;
and choosing RGB instead of YUV as the intermediate (as was done in swscale
v1) is more flexible with regards to enabling further operations such as
primaries conversions, linear scaling, etc.

In the case of YUV->YUV transform, the redundant matrix multiplication will
be canceled out anyways.
