Remove wrong multiple inclusion guards.
Those files are really meant to be included several times.

  • removed MANGLE from macros for setting constants
  • using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
    as its always faster
  • PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
  • replaced original pixels_xy2_mmx with new faster and equal implementation...

  • using unrolled loops seems to help to MMX Celerons
  • calculating average in parallel to use two MMX units
  • disabled xy2 put code - it's producing rouding errors

  • code with new PAVGB for MMX only CPU splited into separate file
    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...
