stream_dvd: better .ifo probing

Browse Source 
stream_dvd.c includes a pseudo-protocol that recognizes .IFO files, and
plays them using libdvdread. This was relatively lazy, and could perhaps
easily trigger with files that just had the .ifo extension.

Make the checks stricter, and even probe the file header. Apparently the
first bytes in an .ifo file are always "DVDVIDEO-VTS", so check for
this.

Refuse to load the main "video_ts.ifo". The plan is to use stream_dvdnav
for it.

This also removes at least 1 memory leak.
