[MPlayer-dev-eng] cvs main vs. libmpeg2

libmpeg2 in main cvs is broken to hell, already enforced by several ppl.
(kabi, vektor, fabian, gabu at least)

so if you'll make release from main, then either fix it (i fear it's
impossible or will result even more ugly hacks) or put back old libmpeg2
(from 0_90, together with vd_libmpeg2.c!).

it does mem corruption now, i have no idea why/where.
the same libmpeg2 is used in g2 and there are no problems, but in g2
libmpeg2 is used 'the right way', ie it handes mpeg-es parsing, while
it's done by demuxer in g1. to workaround this, i've added some hacks
in g1's libmpeg2 to handle special end-of-frame code 0x01ff.
maybe something is broken tehre, or the qscale stuff (g1/s libmpeg2 is
patched to export postprocess data, qscale array) is buggy.
unfortunatelly i have no time nor interest to fix it...
if you don't object i'll put back old libmpeg2 into g1 main cvs.
(it's archived in obsolete module, so it will be easy).

[i hoped that new libmpeg2 will be faster, esp. with gcc 3.x, and it
has altivec support etc, so me and Fabian hacked it to work, but it
seems it doesn't really work as expected.]

note that 0_90 still has old libmpeg2 (0.2.1cvs, while in main it's 0.3.1
