The old code would start in a mixed state, where all the reference
frames were pointing to frame buffer 0, but the reference counts
were 0. This is why we needed special code for the first frame.

Jingning saw bitstream change with this patch. It could be true
that (mask_16x16_0 & 1) is 1, but (mask_16x16_1 & 1) is 0 in some
edge cases.

This reverts commit 8f05e703.

In the decoder we don't need to save eobs, we can pass eob as an argument.
That's why removing eob arrays from VP9Decompressor and TileWorkerData,
and moving eob pointer from macroblockd_plane to macroblock_plane.

This commit makes the coefficient tree initialized prior to token
initialization, where the coefficient costs are filled out according
to the probabilities associated with coefficient value categories.

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
additional work. Also, it's not non-4:2:0 safe.

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.

This commit fixes the use of uv_intra_estimate by properly restoring
the mode_info struct required by rd_pick_intra_sbuv_mode.

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".

Removing goto and using while loop instead, renaming seg_eob to max_eob,
moving eob token counter increment.

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.

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.

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.
