2589ce4a2c tests/swscale: unref buffers before each iteration 
Otherwise, we always pass frames that already have buffers allocated, which
breaks the no-op refcopy optimizations.

Testing with -p 0.1 -threads 16 -bench 10, on an AMD Ryzen 9 9950X3D:

 Before:
  Overall speedup=2.776x faster, min=0.133x max=629.496x
  yuv444p 1920x1080 -> yuv444p 1920x1080, flags=0x100000 dither=1
     time=9 us, ref=9 us, speedup=1.043x faster

 After:
  Overall speedup=2.721x faster, min=0.140x max=574.034x
  yuv444p 1920x1080 -> yuv444p 1920x1080, flags=0x100000 dither=1
    time=0 us, ref=28 us, speedup=516.504x faster

(The slowdown in the legacy swscale case is from swscale's lack of a no-op
refcopy optimizaton, plus the fact that it's now actually doing memory
work instead of a no-op / redundant memset)

271bacffec tests/swscale: exclude init time from benchmark 
This was originally intended to also include performance gains/losses
due to complicated setup logic, but in practice it just means that changing
the number of iterations dramatically affects the measured speedup; which
makes it harder to do quick bench runs during development.

63e0a2add2 avcodec/nvenc: change default H.264 profile from main to high 
The NVENC H.264 high profile provides up to 16% bitrate savings
(BD-Rate measured with VMAF) compared to the main profile.

Since most users do not explicitly set a profile, changing the
default benefits the common case. Users requiring the main profile
for legacy decoder compatibility can still set it explicitly.

The change is gated behind a versioned define so it only takes
effect on the next major version bump (libavcodec 63).
