These functions now are handled through the common superblock code.

Change-Id: Ib6688971bae297896dcec42fae1d3c79af7a611c

* changes:
  tokenize: convert skippable functions
  Add foreach_transformed_block

Use the common block walker to calculate skippability.

Change-Id: I6721e42f065df237426c91c1d871ec226ba7cdcb

Adds a framework for doing arbitrary functions on each transform-
sized block in the mb/sb.

Change-Id: Iaffb1ae8db5ff2abfa8720c608c78376b42f2096

Use sb-common version instead.

With these fixed, the codec produces identical results regardless of
what literal values are used for the enum members in BLOCK_SIZE_*.

Change-Id: I26db8e08019b58ba432af1f0950ebe6b0eb4ad8c

The resulting values are never used.

Merge various super_block_yrd and super_block_uvrd versions into one
common function that works for all sizes. Make transform size selection
size-agnostic also. This fixes a slight bug in the intra UV superblock
code where it used the wrong transform size for txsz > 8x8, and stores
the txsz selection for superblocks properly (instead of forgetting it).
Lastly, it removes the trellis search that was done for 16x16 intra
predictors, since trellis is relatively expensive and should thus only
be done after RD mode selection.

Gives basically identical results on derf (+0.009%).

The unified dequantization, inverse transform, and adding functions
support rectangular block sizes. Also separate the operations on
luma and chroma components, in the consideration of the txfm_size
for uv components in rectangular block sizes.

The strategy to run fast loop filter picking for encoder speed-up
should be revisited at a later stage.

Change-Id: I3b75e06d767cff41be952a42e63b3292f4eab996

Unify the sb32x32 and sb64x64 decoding units, which also allow for
other rectangular block sizes.

Change-Id: Ia5187ab2af56f98c3f99272bdf4dbcabe798ad5d

Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code
gives identical encoder results before and after. There are a few
macros for rectangular block sizes under the sbsegment experiment; this
experiment is not yet functional and should not yet be used.

Change-Id: I8fe25a905717a3cd2da5f87ba0403357536183cf

Modified for option "--enable-gprof".

Change-Id: I07f78f28c1b789c0b3e9e7db3561463551ae5460

Scale factor for second ref frame wasn't assigned in the code.

Change-Id: I6ef3f3f71bd652a879ad847369c54c744782ea37

Renaming vp9_ht_dequant_idct_add* functions to vp9_dequant_iht_add*.

Change-Id: Ie427b322b1cc7c8f39d1155f5df91dedfbd944af

Renaming Y1dequant to y_dequant, UVdequant to uv_dequant, QIndex to qindex.

Change-Id: I1c356e5f886deb3f8807dc212de9799b55b09d58

Adding ALLOWED_REFS_PER_FRAME constant instead of hard coded number 3.

Change-Id: I46146aa837896936f920c748c7d4aa4c27f026e4

Lower case variable names, less code.

Change-Id: I1abc8f592ad2343ab5c76fe2d16262741a4a894a

Restructure the code to avoid the majority of per-block-size
switches, code duplication, etc. All block types (mb/sb32/sb64)
can be handled by the same code.

Change-Id: I4022718d66e31a15a7074e43f3b98cd0a5124ea7

Removing several commented code blocks, using uint32_t and uint8_t types,
removing redundant code.
