* calculating average in parallel to use two MMX units
* disabled xy2 put code - it's producing rouding errors

the new code
* added PAVGP macros for parallel processing to safe few more cycles on
  celerons

Originally committed as revision 625 to svn://svn.ffmpeg.org/ffmpeg/trunk

and being compiled in the same way as _avg.h
* PAVG_MMX macros accept also output parameter
* implemented faster put_pixels_xy2, but it has slightly smaller precission.
  But there is not visible difference in the image quality - might be eventualy
  easily switched back (#if 0 #endif)- please check

for now it's rather sneak preview (new functions are nearly 100% faster)

as its functionality is used even in those parts which are being
  compiled without this flag
  - generaly this would require more complicated cleanup patch
  - for now leaving for the main author
