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

Change-Id: I7df87086708a3d92c5e20e86bcfb04e458ff47a6

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.

Change-Id: I1dc8cf1bcbf056688eee27c7bc5706ac4b4e0125

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.

in most cases at least the left column was a harmless race as it was
left unused later in the code.

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().

Change-Id: I43047c205a1ca2a6e24be44db39dc04b7a385008

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.
