wm4 466fc6d4d1 sub: make it easier to set DVD sub decoding with sd_lavc 
With this commit, the player will still use spudec.c (the "old" DVD sub
decoder), rather than ffmpeg. But it brings the changes needed to enable
this down to a single line change:

--- a/mplayer.c
+++ b/mplayer.c

         vo_osd_changed(OSDTYPE_SUBTITLE);
     } else if (track->stream) {
-        if (mpctx->sh_sub->type == 'v')
+        if (mpctx->sh_sub->type == 'v' && false)
             init_vo_spudec(mpctx);
         else
             sub_init(mpctx->sh_sub, mpctx->osd);

Also, copy the DVD resolution heuristics from spudec.c (from the
spudec_new_scaled() function). I'm not sure if this is correct or even
needed, but the sd_lavc codd explicitly reverted back to spudec with
code carrying this comment:

    // Assume resolution heuristics only work for PGS and DVB

so it seems likely that the required heuristics were missing, and that
the spudec heuristics may make the DVD compatibility situation at least
as good as with spudec.

Note that it's unlikely that we enable sd_lavc for DVD subs by default,
as there are other problems in combination with direct DVD playback.
