wip/airconnect 1.8.3 NetBSD

AirConnect is a collection of programs that allow AirPlay clients to play to UPnP/DLNA and Chromecast devices that do not natively support AirPlay.

It includes:

• airupnp: Bridge between AirPlay and UPnP/DLNA/Sonos players
• aircast: Bridge between AirPlay and Chromecast devices

AirConnect can run on any machine that has access to your local network. It does not need to be on your main computer. (For example, a Raspberry Pi works well). It will detect UPnP/Sonos/Chromecast players, create as many virtual AirPlay devices as needed, and act as a bridge/proxy between AirPlay clients (iPhone, iPad, iTunes, MacOS, AirFoil ...) and the real UPnP/Sonos/Chromecast players.
