Saxon 82d9e5e8bd codec/mjpeg: tidying up 
Separated my code from code that was ported from ffmpeg (differen copyright). Also added utils.go file to house the putBuffer and bytestream types. Reduced copying and use of bytes.Buffer.
Instead expanded putBuffer functionality so that I can use this throughout process (reduce copying from buffer to buffer).

Saxon a6797a929d revid: defaulting to VBR for camera devices 
Easiest way to do this is change VBR config field to CBR (therefore CBR defaults to false without having to do anything).
