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.

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.

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.

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.

Took vp9_setup_scale_factors_for_frame() out from
vp9_setup_interp_filters(), so that it is only called once per
frame instead of per macroblock. Decoder tests showed a 1.5%
performance gain.

Change-Id: I770cb09eb2140ab85132f82aed388ac0bdd3a0aa

General code cleanup in loopfilter code. Modification of setup_frame_size,
so now VP9_COMMON is modified in one place after all width/height checks
passed.

Change-Id: Iedf32df43a912d7aae788ed276ac6c429973f6fe

Decomposition vp9_decode_frame function, moving code into read_txfm_mode
and setup_pred_probs functions.

Change-Id: I90970dea43cbcef4d6d61fdef267c2094ddee65d

Renaming sb32_coded to prob_sb32_coded and sb64_coded to prob_sb64_coded.

Rename the file and clean up includes. In the future we would like to
pattern match the files which need additional compiler flags.

Change-Id: I2c76256467f392a78dd4ccc71e6e0a580e158e56

Adding decode_sb_8x8 and decode_sb_4x4 with common code for superblock
decoding. Renaming decode_superblock32 to decode_sb32 and
decode_superblock64 to decode_sb64.

Change-Id: Id006d7e398b9bfa3acec4326e1e0c537ebfefdd3

Using clamp and MIN/MAX functions instead of plain C code. Lower case
variable names. Removing redundant parenthesis.
