Subject: Patch for bug in SDL cdrom resume handling

Black| pointed out a bug on #sdl today, that when you pause CD playback,
and then Resume it, it'll play until the end of the disk, and not until
the track you specified.

Attached is a patch that fixes the issue, by saving the desired end position
in the SDL_CD struct, and seting it again upon resume
