summary: This patch modifies the `curves` filter with new `interp` option
to let user pick the existing natural cubic spline interpolation
and the new PCHIP interapolation.
reason: The natural cubic spline does not impose monotonicity between
the keypoints. As such, the

When building on Windows (CYGWIN or WSL), generated .d files contain the
MSYS2/CYGWIN path format (i.e. C:/MyRepos/ffmpeg).
This causes make commands such as clean an install to fail when running on WSL.
This patch detects whether WSL is being used and converts the paths to standard
UNIX paths (i.

It does not require anything that is being set between
the new position where it is called and the old position
where it used to be called; and nothing that it sets
gets overwritten between these two positions.
Doing so allows to remove a check lateron.

Simply taking the Zbb REV8 instruction into use in a simple loop gives
some significant savings:
bswap_buf_c: 1081.0

just one additional shift, and one fewer load, effectively
