(CDAudio_Init): Move the bad ugly hack about SDL_CDROM environment
variable into the new export_cddev_arg() helper. FOr the -cddev option,
call the new get_cddev_arg() helper.
(export_cddev_arg): SDL_CDROM environment variable hack moved from
CDAudio_Init() to here. Fixed bad strcat() usage orto the array. Made it
for non-windows platforms only.
(get_cddev_arg): Added for checking the argument to the -cddev option.
For non-windows platforms just return the argument itself. For windows,
arg should be like "D:\", make sure it is so, but tolerate args like "D"
or "D:", as well.
(CDAudio_Next): Make static. Minor cleanups.
(CDAudio_Prev): Make static. Minor cleanups.
