Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.

That makes decoder and encoder (only bitstream writing part) a little bit
simpler and faster. Moving get_sb_index() function to the encoder.

Making this change in order to move allow_high_precision_mv field
from MACROBLOCKD structure to VP9_COMMON (because it is a frame level
flag).

* changes:
Use a separate MODE_INFO stream for each tile column
Get rid of "this_mi", use "mi_8x8[0]" everywhere instead
Make the static_segmentation feature work again
The only case where they were intentionally pointing to different
structures was in mbgraph, and this didn't have the expected behavior
because both of these pointers are used interchangeably through the code

Moving code that gets band_translate array from get_scan_and_band()
function to get_band_translate() function. Renaming get_scan_and_band() to
get_scan().

This should be similar to what x264 does with --aq-mode 1.
It works well with clips like parkjoy and touhou
(http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv).
At low bitrates, the segmentation signaling overhead may negate the
benefits of this feature.
(PGW) Default changed to feature OFF to allow provisional merge.

Updated the encoder to handle frames that are coded
intra-only. Intra-only frames must be non-showable,
that is, the "show frame" flag must be set to 0 in
the frame header.
Tested by forcing the ARF frames to be coded intra-
only.
Note: The rate control code will need to be modified
to account for intra-only frames better than they
are currently handled.

Remove the semicolon in the definition of vp9_zero macro. Make all
the use cases of vp9_zero of consistent format.

Use the zcoeff_blk buffer of PICK_MODE_CONTEXT to store the indexes
of all-zero-coeff block of the current best mode. Remove the temporary
buffer best_zcoeff_blk defined in the rate-distortion optimization
loop. This improves the speed performance by about 0.5% in all speed
settings.

This commit moves token_cache buffer into macroblock struct, instead
of defining as a local variable in cost_coeffs. This avoids repeatedly
re-allocating memory space in the rate-distortion optimization loop.
The runtime at speed 0 reduces:
bus 2000kbps, 161692ms to 159951ms
football 600kbps, 229505ms to 225821ms
