0.15% quality increase on derf, particularly noticeable on hard clips
at the higher bitrate end.

* changes:
  Move EOB to per-plane data
  Move qcoeff, dqcoeff from BLOCKD to per-plane data

This is a VP8-only feature (part of profile 3) that is unsupported in
VP9.

Cleaning up the code, removing unused vp9_check_segref_inter function and
useless comments.

Continue migrating data from BLOCKD/MACROBLOCKD to the per-plane
structures.

Change-Id: Ibbfa68d6da438d32dcbe8df68245ee28b0a2fa2c

Start grouping data per-plane, as part of refactoring to support
additional planes, and chroma planes with other-than 4:2:0
subsampling.

so it is configurable to faciliate testings

Adds back special casing B_PRED mode decoding but protected
within the experimental macro.

Fixes an indexing bug. Looks like the bug has been there for a while.

Change-Id: I9fc04b0c30754bcb47366ad94a08112925600c4d

Inside decode_sb_4x4 it should be
"get_tx_type_4x4(mb, y_idx * y_size + x_idx)"
but it was
"get_tx_type_4x4(mb, y_idx * (2 * y_size) + x_idx)".
Also making code of decode_sb_4x4, decode_sb_8x8, and decode_sb_16x16
formatted in the same way.

This function expects real Q values as inputs
not index values.

The use-age her impacts the Q chosen for force key
frames. Though this is a bug fix I have not yet verified
whether following the bug fix the q multiplier value used is
correct.

Change-Id: I49f6da894d90baeb1e86c820c335f02dc80d3b66

Making code more readable in different places.

Change-Id: Iea92c9a35e64d257ee358879fc04fc926843d52e

Moving command code from decode_sb32 and decode_sb64 into new
decode_sb_16x16 function.

Change-Id: I57a161300af085557adec2fe600f3c10a145faf2

Better formatting, shorter code, adding read_switchable_filter_type
function.

This code was only called in the BPRED case, but had no real special
case associated with it. Made BPRED behave like all other modes. No
bitstream change.
