[Cin] Some possible thirdparty updates I noticed

[Phyllis Smith]

Andrew-R et al,
FFmpeg is good to keep up to date for sure.

But... please refer to section B.4 for more details about upgrading 3rd
party libraries.  Here is a summary though:

Biggest problem can be on the older distros, like maybe Ubuntu 16, and with
little used packages such as OpenEXR, wepb, libaom, libvpx, x10tv, OpenCV,
and Dav1d.  I would hate to see users with older distros prevented from
using CinelerraGG.  I would not update any of these but users who really
want them can do their own builds as recommended in section B.4.
