libx265: Enable 12-bit encoding

Multimedia / FFmpeg - Stephen Hutchinson [gmail.com] - 31 January 2016 18:36 UTC

The configure detection is bumped to X265_BUILD >= 68, since API version 68 corresponds with the x265 1.8 release tarball. The warnings inside x265 about 12-bit being experimental were removed prior to API
version 72 a short time later. At this time of writing, X265_BUILD is at version 80.

12-bit support in the HEVC standard was approved in October 2014 as part of HEVC Version 2 and published in January 2015:
