required to upgrade libvlccore8 to libvlccore9 because, of course, the
latter is a different package.
libvlccore8 is based on VLC version 2 and libvlccore9 is based on VLC 3.
VLC is susceptible to DSA-4203 (CVE-2017-17670), so VLC 3 has been fixed
in 3.0.2. As VLC 2.x will not get fixed, stretch had no alternative
but to move from version 2 to 3.
