[Mplayer-dev-eng] Largefiles patch

Hi, Here's my largefiles patch again; against today's CVS. I removed the %qd's, mostly. Where I thought they should stay, I ifdeffed for _LARGEFILE_SOURCE. And replaced %qd with %lld - I see that "q" is deprecated in the printf man page. Your comments and I'll make a final tweak if necessary. Steve
