This commit fixes the intra prediction reference source selection
in the settings of skip_encode. Use original boundary pixels as
prediction reference, when the inverse transform and reconstruction
are skipped in the per block size rate-distortion optimization loop.

Its last remaining caller can be passed its results directly without any

The performance gain of idct16x16_10_add_sse2 function is not
noticeable. However since both functions use the IDCT16_1D,
idct16x16_10_add_sse2 should be modified as well.

The difference with the old code is that originally the whole token_cache
was initialized with zeros at the beginning of decode_coefs() function.
Now we set several zero values explicitly with "token_cache[scan[c]] = 0".

E.g. disable vertical partioning for 4:2:2. Until we come up with something
better to do with the chroma block size, this prevents an assert error.

Considering a horizontal edge, if mask_16x16 is 1 for an even-
indexed 8x8 block, then mask_16x16 is 1 for next 8x8 block in
same row. Similiar to a verticle edge, if mask_16x16 is 1 for
an even-rowed 8x8 block, then mask_16x16 is 1 for the 8x8 block
right below it in next raw. Based on that, the mask_16x16 checking
can be simplified to save cycles. The corresponding 8-pixel
vp9_mb_lpf_horizontal_edge code can also be removed.

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.

When calling check_initial_width through vp9_set_size_literal
the function was defaulting to using non-subsampled chroma.
This patch changes the default to assume sampled chroma as
an interim solution until complete support for other
color formats is added.

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 patch followed "Add filter_selectively_vert_row2 to enable
parallel loopfiltering" commit, and added x86 SSE2 optimization
to do 16-pixel filtering in parallel. For other optimizations
(neon and dspr2), current 16-pixel functions were done by calling
8-pixel functions twice, and real 16-pixel functions could be added
later.
Decoder speedup:
tulip clip: 2% speed gain;
old_town_cross: 1.2% speed gain;

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.

This patch fixed issue 661: "Decoder produces mismatched outputs

be arranged carefully to prevent incorrect overflowing.
