ratecontrol: patch by Loren Merritt <lorenm AT u DOT washington DOT edu>

"The new cbr mode fails to completely disable itself when encoding in
constant QP mode. The per-block QPs are then randomized between QP+4 and
QP-2 based on uninitialized ratecontrol parameters."

* all: Change the way PSNR is computed (based on a patch by Loren
Merritt <lorenmn AT u DOT washington DOT edu>
Using SQE(DeltaSourceReconstructed) = Sum( delta^2 )
       PSNR( SQE, Size ) = -10Ln(SQE / 255^2 / Size )/Ln(10) )
       Y+U+V : Union of YUV planes.

Now there is
  - Mean PSNR : Sum( PSNR( SQE(Y/U/V), Size(Y/U/V) ) / TotalFrames
  - Average PSNR: Sum( PSNR( SQE(Y+U+V), Size(Y+U+V) ) ) / TotalFrames
  - Global PSNR: PSNR( Sum( SQE(Y+U+V) ), Size(Y+U+V)*TotalFrames )

  Mean PSNR is used by the JM, and Average/Overall is used on Doom9 for
example.

"Here's a patch that adds some kind of rate control. I suppose it is
by no means perfect, but it's much better than constant quantizer. It
also has a very crude scene change detection that sometimes avoids a
buffer underflow by reencoding oversized P/B frames as I frames."
