* Streams are a 4 stage process.
* 1) start buffering stream 5 seconds ahead of its start time
* 2) at the start time tell liquidsoap to switch to this source
* 3) at the end time, tell liquidsoap to stop reading this stream
* 4) at the end time, tell liquidsoap to switch away from input.http source.
*
* When we have two streams back-to-back, some of these steps are unnecessary
* for the second stream. Instead of sending commands 1,2,3,4,1,2,3,4 we should
* send 1,2,1,2,3,4 - We don't need to tell liquidsoap to stop reading (#3), because #1
* of the next stream implies this when we pass in a new url. We also don't need #4.
*
* There's a special case here is well. When the back-to-back streams are the same, we
* can collapse the instructions 1,2,(3,4,1,2),3,4 to 1,2,3,4. We basically cut out the
* middle part. This function handles this.
