I don't see the point/difference. The do read subtitles (stream_read_line etc.),
but of course they also load it. One without the other makes little sense.

In theory you should be able to load one subtitle per vo_vobsub struct.
However having more than one probably isn't tested at all, and changing
vo_vobsubs during playback might be real tricky.
However, it means it would be a good idea if load_vob_subtitle returned
the allocated vobsub struct instead of assigning it to vo_vobsub itself.

It is fine (though as said I'd appreciate it if you try to ensure you make
doing this properly not harder, i.e. keep assinging vo_vobsub as much top-level
as reasonably possible).

Dropping features is not appreciated much.
Also last I checked quite a few people seemed to be using it, so it shouldn't
be working that badly...
