[Bf-committers] Library updates for Blender 2.8

[Ray Molenkamp]

There's quite a few libraries we build for the various platforms
(57 by the last count) and it's not always clear who the module
owner is and who is supposed to ask for newer versions of certain
libs. 

I took a quick survey of the versions we use and the latest versions
available. (based on build_files\build_environment\cmake\versions.cmake)

https://docs.google.com/spreadsheets/d/e/2PACX-1vRnu75FDmw8NvbJiH9hjrGNBvrwXU9ocWWMCWZY0ISwcfLOnL7Ep1z67Y5FpN_TaI0QRwbPR2KmrQie/pubhtml?gid=0&single=true

(or in case the email ruins the long link: https://tinyurl.com/y9st4fyt )

There are several libs with known CVE's, personally I would prefer
to upgrade those to the latest versions (most seem low risk upgrades)
but for everything else I really have no strong opinion.

Any module owner that wants edit rights, please poke me (email/irc) and
I'll get you an editable link.
