Changed FFMIN/FFMAX to av_clip_uint16 and av_clip_uint8.

Here are updated patches with fixes. I updated conversion functions, so
they should

I split patch to one for libavutil and another for libswscale,
also added LUT for unscaled conversion, added
conversions for scaling and updated fate tests.

This patch adds two floating-point gray formats to use them in sr filter for
conversion with libswscale. I added conversion from uint gray to float and
backwards in swscale_unscaled.c, that is enough for sr filter. But for
proper format addition, should I add anything else?

Hello,
These patches address several raised concerns regarding sr filter
and DNN module. I included three patches, that I've already sent,
but they still have not been reviewed properly.
libavfilter: Adds on the fly generation of default DNN models for
tensorflow backend instead of storing
This patch removes conversions, declared inside the sr filter, and uses
libswscale inside
the filter to perform them for only Y channel of input. The sr filter still has
uint
formats as input, as it does not use chroma channels in models and these
channels are
upscaled using libswscale, float fo
