this also fixes a possible security issue (the sps and pps ids where not checked,
then used as index into an array of sps/pps structs which was then filled with data from the bitstream)

optimize sign decoding code in decode_residual()
...
x86 is 4% faster on P3
C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C)
... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all
