The idea here is to allow "in frame" adjustment of the final Q
value used to encode each SB64, using segmentation.

There is also adjustment of the rd mult in regions of overspend.

The decoder will construct inter predictor using lazy border extension,
while the encoder, going with multiple runs of motion search in the rate-
distortion optimization loop for each block, does border extension at
frame level. This commit makes separate the inter predictors for encoder
and decoder, respectively.

This function is also used with the U and V planes.

This commit takes out vp9_extend_frame_borders from
vp9_setup_scale_factors.

The refactoring is for the preparation of the use of lazy border
extension at decoder. This makes it necessary to handle border
extension separately at encoder/decoder. The use of
vp9_extend_frame_borders will be removed, when lazy border extension
is ready.

The decoder ignored the display width & height
specified in the frame header.

This patch adds a control, VP9D_GET_DISPLAY_SIZE, to
allow the application to obtain the display width and
height from the frame header.

vpxdec has been modified to scale the output frame to
this size.

Should the request for the display size fail vpxdec will
use the native width and height of the raw decoded
frame instead.

This fixes issue 667.

In the case where the frame was an odd number of pixels
wide or high, the border was being extended by one col
or row too far.

The calculation of color plane dimensions was modified
to use those already computed at the time the frame
buffer was allocated.

Also freed the temporary scaling buffer in vpxdec to
prevent a memory leak.

* changes:
  detokenization speedups
  Don't write 0's to token_cache

Moves all rate control variables to a separate structure,
removes some currently unused variables,
moves some rate control functions to vp9_ratectrl.c,
and splits the encode_frame_to_data_rate function.

- Rename the struct to VpxEncoderConfig.
- The idea behind this is to enable checking the global settings against
  stream specific settings in source files other than vpxenc.c.
