port:VLC version 3.0.4

[René J.V. Bertin]

Hi,

There have been a few recent issue reports about port:VLC on Trac, as well as a somewhat older upgrade request.

I now have a working upgrade to 3.0.4 that should be compatible with 10.14 thanks to Michael Lass:

https://github.com/RJVB/macstrop/tree/master/multimedia/VLC

This port replaces the previous port:VLC-test. Users on 10.13 and earlier are stuck with VLC 2.x, now provided by port:VLC2, UNLESS they only used port:libVLC on 10.9 (I managed to get that to build on 10.9 too). I've allowed port:libVLC2 to be installed up to and including 10.11; port:libVLC builds from 10.9 and later.

The upgrade to the proper version should happen automatically, but dependents of libvlccore will require a revbump (I'm not aware of any such ports except in my own repository).

Interested parties are cordially invited to test-drive the new port and report back, before I submit the entire change for review.
