replaces use of cur_tile_mi_(row|col)_(start|end) by VP9_COMMON, making
it less stateful and more reusable for parallel tile decoding

update_partition_context / partition_plane_context: this will allow for
separate storage to be used in tile decoding

Splitting setup_inter_inter function into is_compound_prediction_allowed
and setup_compound_prediction. Moving setup_compound_prediction call
into read_comp_pred from read_uncompressed_header.
We should do the same in the encoder as well.

Assign the pointer to mode_info stream per tile. Remove the use of
tile_col in the decoding modules.

This move is done to have all compressed header reading functions in one
place. Moved functions:
read_switchable_interp_probs
read_inter_mode_probs
read_comp_pred_mode
read_comp_pred
update_mv
read_mv_probs

The ref's scale_factors are set at frame level, and then copied for
each partition block. Since the struct members are mostly constant,
this patch separated the constant and non-constant members, and
reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain.

This commit uses left_available flag to decide if the left mode_info
struct is available for left_block_mode. As discussed with James
Zern (jzern@), this prevents the codec from fetching mode_info from
blocks in the left tile, which although effectively not used might
present concerns for multi-threaded tile decoding.
This is NOT a bit-stream change.

We used set_partition_seg_context() only before calls to:
1. update_partition_context()
2. partition_plane_context()
Moving these functions from vp9_blockd.h to vp9_onyxc_int.h and
inlining set_partition_seg_context into them. After that it is not
necessary to have {above, left}_seg_context fields in MACROBLOCKD struture,
so removing them also.

missed one in vp9_detokenize.c in the last
+ add some asserts in vp9_decode_frame() to catch regressions

replace VP9D_COMP usage with the (slightly) more targeted
VP9_COMMON/MACROBLCKD/struct segmentation structures.

Renames for consistency with other constants:
NUM_FRAME_TYPES -> FRAME_TYPES
NUM_PARTITION_CONTEXTS -> PARTITION_CONTEXTS

in most cases at least the left column was a harmless race as it was
left unused later in the code.
Change-Id: I43211df66fb157c6feecf08c681add4fcf18b644
That makes decoder and encoder (only bitstream writing part) a little bit
simpler and faster. Moving get_sb_index() function to the encoder.

add WebPWorkerExecute() for convenient bypass
This is mainly for re-using the worker structs without using the
thread.
