Use of `<shoutcast-compat>` results in unexpected behaviour

When setting <shoutcast-mount> within <listen-socket> two sockets will be created:

  • A normal one with the shoutcast mount set
  • A second one at (port + 1) with shoutcast mount set as ICY source port (<shoutcast-compat> set).

However you can set <shoutcast-compat> manually. In this case also two ports are opened at port and port + 1 with both being identical in configuration.

The code uses the following condition to check if the extra socket must be created:

    if (listener->shoutcast_mount) {

However I think it should be:

    if (listener->shoutcast_mount && !listener->shoutcast_compat) {

This will prevent the listen socket on port + 1 to be created.
