Merge branch 'master' into blender2.8

OpenJPEG: support building against both 1.5 and 2.3.

Patch porting to OpenJPEG 2.3 is by Campbell.

Once all platforms are upgraded we can remove the code for 1.5, and upgrade
or remove the openjpeg version from extern/. This intermediate step makes it
possible for platform maintainers to upgrade to 2.3 without breaking other
platforms.

Build: fix ffmpeg using system crystalhd library.

UI: move grease pencil entry in add menu.
