Remove libdvdread support in favor of libdvdnav
stream_dvd.c contained large amounts of ancient, unmaintained code, which has been historically moved to libdvdnav. Basically, it's full of low level parsing of DVD on-disc structures. Kill it for good. Users can use the remaining dvdnav support (which basically operates in non-menu mode). Users have reported that libdvdread sometimes works better, but this is just libdvdnav's problem and not ours.
