intf.c, vcdplayer.c: Add code for multi-default selection lists. But 

this required new libvcdinfo API - so change to configure.ac for
pending new libcdio/vcdimager releases.

Additional libvcdinfo routines also means less VCD twidling inside vlc
code, thus simplifying what is already a bit complicated and likely to
get more so.
