Fix rate control when --owf=auto (default)
...
Value in cfg stays -1 if auto selection is used.
Use value in encoder instead.

When rate control is disabled, QP and lambda are now selected like they
were before rate control was implemented.

Move initialization of constants to encoder.c.
...
Some constants used in rate control are now initialized only once instead
of being computed on every frame. Adds pixels_per_pic, target_avg_bppic,
target_avg_bpp and gop_layer_weights to encoder_control_t.

Select GOP picture weights according to bitrate.
...
Pictures in same layer have equal weights. At low bitrates, the difference
between low and high layers is greater than at high bitrates.
