albeu 7562937d95 Improvment for spu subtitles.
Removed the integreted spudec in vobsub.
Various cleanup/bugfix in vobsub (no more auto palette when a true one is
here)
HW spu rendering moved in spudec because we first need to reassable the
packet before sending them to the hw.
Spudec is now created only if nedded.
