[Cin] x264 update to latest master

i encoded one 10bit/444 video, it seems to work fine... but of course better testing will be very useful) it seems i can't attach repacked sources due to very slow internet / just put content of x264 git cloned folder into x264-snapshot-20210615 and tar it, and then xz it too.... $ git clone https://code.videolan.org/videolan/x264.git $ mkdir x264-snapshot-20210615-master cp -ar x264/* x264-snapshot-20210615-master/ tar -cf x264-snapshot-20210615.tar x264-snapshot-20210615-master xz - 9 x264-snapshot-20210615-master.tar
