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).

startRTSPCamera is returned.

Two fixes were involved, firstly, access unit delimeters were used to denote access units and the Write timeout on rtmpSender's ringBuffer was
increased to stop the 'unable to dump old write' errors. Also made some small changes elsewhere that should fix future issues, particular with
MTS output.
