* Added the QuickTime RTSPtext redirect system. uses m3u, even though they are not related.
* Added the WM Server [Reference] redirects to the pls playlist demux. it's also INI based.

This fixes #690

* malloc with NULL check
* file extension check
* check if a demux was forced
* try peeking, and check what we poke
* init standard demuxer fields
* create packetizers

  - some elements are not yet supported.
  - it could perhaps use a little bit more cleaning.

In the basics. It just works :D
