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 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.

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.

Using for loop based on max_tx_size instead of separate checks. Combining
build_coeff_contexts() with update_coef_probs().

Modifications are done to reduce the total clock cycle.

Both functions have no relation to motion vectors, so moving them from
vp9_findnearmv.h to vp9_blockd.h.

Added filter_selectively_vert_row2 to be ready for parallel
loopfiltering in vertical direction. This change did 2-row
filtering at a time. If 2 vertically adjacent 8x8 blocks do same
type of filtering, we can do 16-pixel filtering in parallel.
Next, we need to provide 16-pixel loopfiltering functions in c
and optimized versions for codec speedup.

Add support to do 16 pixel horizontal filtering in Neon.
Nexus devices saw about 0.5% decode speed increase.

This function is called from vp9_setup_past_independence() which is called
before the modified piece of code. Moving reset of inter_mode_probs into
vp9_init_mbmode_probs() for consistency.
