AxisAPI legacy

Elphel 3x3 cameras have own implementation of Axis Video API version 2.xx.

The HTTP-based video interface provides the functionality for requesting single and multi-part images and for getting and setting internal parameter values. The image and CGI-requests are handled by the built-in Web server in the cameras.

Elphel Axis Video API extension proposes some additional possibility. For example, functionality for requesting RTP MJPEG, HTTP Ogg/Theora or RTP Ogg/Theora video streaming.
