This prevents a duplicate memcpy of a 128-byte struct every time
set_scale_factors() is called (which is a lot), thus leading to a
decrease from 3.7 MB to 1.85 MB of struct copying per 64x64 block
RD/partition loop.
Overall, this decreases encoding time of the first 50 frames of bus
@ 1500kbps (speed 0) from 1min5.9 to 1min4.9, i.e. about a 1.5%
overall speedup. We can likely get more gains by removing the copy
of the other struct (and replacing it with an indexing) as well.

Removing tile_rows and tile_columns from VP9Common, removing redundant
constants MIN_TILE_WIDTH and MAX_TILE_WIDTH, changing signature of
vp9_get_tile_n_bits.
Change-Id: I8ff3104a38179b2c6900df965c144c1d6f602267
Making implementation of vp9_set_pred_flag_{seg_id, mbskip} consistent
with vp9_get_segment_id without using confusing sub(a, b) macro. Passing
mi_row and mi_col to functions explicitly instead of replying on
mb_to_right_edge and mb_to_bottom_edge.
Change-Id: I54c1087dd2ba9036f8ba7eb165b073e807d00435
Removing unused DEC_DEBUG define and dec_debug variable. Changing function
signatures to eliminate code duplication, renaming function
mb_init_dequantizer to init_dequantizer. Also removing redundant curly
braces, and comments.
Change-Id: Ia56ee1b0be5f24abb0e878581845be8a4773c298
Adding segmentation struct to vp9_seg_common.h. Struct members are from
macroblockd and VP9Common structs. Moving segmentation related constants
and enums to vp9_seg_common.h.
Change-Id: I23fabc33f11a359249f5f80d161daf569d02ec03
Adding read_skip_coeff function. Renaming decode_mv to read_mv for
consistency with another function names. Removing redundant function
arguments. Renaming kfread_modes to read_intra_mode_info, read_mb_modes_mv
to read_inter_mode_info, vp9_decode_mb_mode_mv to vp9_read_mode_info,
vp9_decode_mode_mvs_init to vp9_prepare_read_mode_info. Inlining function
mb_mode_mv_init inside vp9_prepare_read_mode_info.
Change-Id: Ifee05d333da4cd331d4aff40ce41ccd9b70e494a
Adding CHECK_MEM_ERROR macro to vp9_common.h and removing two duplicated
ones from vp9_onyx_int.h and vp9_onyxd_int.h.
Change-Id: I916afec61b3019f18193135dac7c35ed0f89b8b6
Using vp9_set_pred_flag function instead of custom code, adding
decode_tokens function which is now called from decode_atom,
decode_sb_intra, and decode_sb.

This commit enables configurable reference buffer pointer for intra
predictor. This allows later removal of spatial dependency between
blocks inside a 64x64 superblock in the rate-distortion optimization
loop.

All elements of this table are equal to 252, so replace it with a
single constant VP9_COEF_UPDATE_PROB.

Avoid calling decode_block, inverse transform/add in the block is
a skip block for SBs smaller than 8x8 and intra-coded SBs.
Change-Id: I1684182f4a0050c8d6bb46cba6830d9425e7127d
Previous code indexed using the tile length coded in the bitstream
without checking that the read would be valid.
Change-Id: Ia5047762223a4f80d75016dd546dc2ef18b6887d
Removes the case of coding prob = 0 for forward updates, since that
is not an allowed probability to code.
Slightly improves efficiency but may not matter in practice.
