Move the URL parsing code from m_option.c to stream.c, and simplify it dramatically. This code originates from times when http code used this, but now it's just relict from other stream implementations reusing this code. Remove the unused bits and simplify the rest. stream_vcd is insane, and the priv struct is different on every platform, so drop the URL parsing. This means you can't specify a track anymore, only the device. (Does anyone use stream_vcd? Not like this couldn't be fixed, but it doesn't seem worth the effort, especially because it'd require potentially touching platform specific code.)
