vpx_codec_vp9x_cx is not used internally. Experimental flag from
vp9_extracfg is also not really used. YUV 4:4:4 just works after these
changes (you have to specify --profile=1 for the encoder).

Buffer the SSE of prediction residuals in the rate-distortion
optimization loop of a given block. This information would be used
for later encoding control.

Moving all code from that files to vp9_mvref_common.{h, c}.

Moving back to scale_factors struct. We don't need anymore x_offset_q4 and
y_offset_q4 because both values are calculated locally inside vp9_scale_mv
function.

Before mv scaling it is required to calculate x_offset_q4/y_offset_q4
by calling set_scaled_offsets(). Now offset configuration can not be
missed because it happens just before scale_mv().

The original iterative search was replaced by subpel_tree search,
and was not used anymore.

Removed unused filter coefficients.

Various cleanups and streamlining of interfaces as precursor
to further advancements in rate control.
Pre-encode parameter setting for different use cases:
One-pass, first of 2-pass, second of 2-pass, and Svc
are separated out.

There is no change in output with this change.

Take account of the fact that the overlay frame is usually
very cheap so distribute target bits among the other frames.

This will hurt metrics in some cases (particularly for static
clips at low data rates where there is extra overhead, but it
helps smooth transitions around forced key frames between
stitched kf sections.

Slightly reduces the mean tendency to undershoot target
rate in vbr, especially when using the memory less mode
and when recodes are disabled.

The effect is primarily at low q.
