396a5e6837 store a few values in the header as difference to the last 
this makes frames a few bytes smaller (0.1% for high bitrate but >1% for low bitrates)

2f16af0667 skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome)

59743d16c7 dont randomly disallow intr4v in adaptive quant 
some PSNR/bitrate gain if adaptive quant is used
initalize qscale_table correctly (it was pretty much random since the qp->lambda change)
  this probably has not much effect as the table isnt used currently IIRC

e7a6d5f313 Bug fix for crashes when SSE is used on unaligned arrays. 
No measureable change in speed. This gave random crashes on Win32
and BeOS. The cause for this bug is that gcc doesn't align the
stackframe. Linux and glibc always ensure this to be true thus
this never affected Linux.
