Import vlc-2.1.1 as wip/vlc21.

VideoLAN is a project of French students from the Ecole Centrale Paris
and developers from all over the world. Its main goals is MPEG streaming
on a network, but it also features a standalone multimedia player. The
VideoLAN Server can stream video read from a hard disk, a DVD player,
a satellite card or an MPEG 2 compression card, and unicast or multicast
it on a network. The VideoLAN Client can read the stream from the network
and display it. It can also be used to display video read locally on
the computer : DVDs, VCDs, MPEG and DivX files and from a satellite
card. It is multi-plaform : Linux, Windows, Mac OS X, BeOS, BSD, Solaris,
QNX, iPaq... The VideoLAN Client and Server now have a full IPv6 support.

TODO:
This version removes OSSv3 support.
Either bring it back (using code from previous version)
or fix NetBSD to provide it -- or import it anyway and use
a different sound system.

Compiles & packages, not runtime tested yet.
