wm4 c157641019 stream_cdda: remove weird option parsing stuff 
Mostly untested.

This is not compatible. It removes the URL fields for track range and
cdrom speed (what did this even do). The device is not not to be
prefixed with an additional "/" if it's put into the URL. I can't be
bothered to keep these things compatible, just rip your damn CDs
instead.
