The idea is to have the following names for each transform size:
vp9_idct4x4_add
vp9_idct4x4_1_add
vp9_idct4x4_10_add
vp9_idct4x4_16_add
vp9_idct8x8_add
vp9_idct8x8_1_add
vp9_idct8x8_10_add
vp9_idct8x8_64_add
etc for 16x16, 32x32
The actual list of renames in this patch:
vp9_idct_add_lossless -> vp9_iwht4x4_add
vp9_short_iwalsh4x4_add -> vp9_iwht4x4_16_add
vp9_short_iwalsh4x4_1_add -> vp9_iwht4x4_1_add
vp9_idct_add -> vp9_idct4x4_add
vp9_short_idct4x4_add -> vp9_idct4x4_16_add
vp9_short_idct4x4_1_add -> vp9_idct4x4_1_add

Moving INTERPOLATIONFILTERTYPE enum and subpix_fn_table struct to
vp9_filter.h. Adding convenient typedef for subpel kernels.
Function vp9_setup_interp_filters() besides setting xd->subpix.filter_x &
xd->subpix.filter_y has a side effect of also setting scale factors. This
is not required inside decode_modes_b() because scale factors have been
already set by set_ref() calls. That's why replacing
vp9_setup_interp_filters() call with newly created vp9_get_filter_kernel()
call. The behavior of vp9_setup_interp_filters() is unchanged (it
is used from the encoder).

This patch reverts old commit 398ddafb629b7f49cf255bf09d3e38b4abd0bb95
"New way of updating last frame segmentation map.".

Moving functions from vp9_idct_blk to vp9_idct because these functions are
used from both encoder and decoder. Removing duplicated code from
vp9_encodemb.c and reusing existing functions.

The codec should effectively run with motion vector of range (-2048, 2047)
in full pixels, for sequences of 1080p and below. Add assertions to clarify
this behavior.

Moving out decode_tokens function calls and adding decode_blocks boolean
variable. We only have to decode if eobtotal > 0, i.e. we have at least one
non-zero coefficient. Also inlining and remove vp9_set_pred_flag_mbskip
function.

We don't need these functions anymore. The only one which was actually
used is vp9_add_constant_residual_32x32. Addition of
vp9_short_idct32x32_1_add eliminates this single usage. SSE2 optimized
version of vp9_short_idct32x32_1_add will be added in the next patch set,
right now it is only C implementation. Now we have all idct functions
implemented in a consistent manner.

apparently we are going to have trouble completely removing lint issue in this file.
It needs a bit more work. We need to include vpx_config.h to know whether
we need to have multi threading . and that means vpx_config.h has to come
before the system headers. ( a violation )

The probability model used to code prediction mode is conditioned
on the immediate above and left 8x8 blocks' prediction modes. When
the above/left block is coded in sub8x8 mode, we use the prediction
mode of the bottom-right sub8x8 block as the reference to generate
the context.
This commit moves the update of mbmi.mode out of the sub8x8 decoding
loop, hence removing redundant update steps and keeping the bottom-
right block's mode for the decoding process of next blocks.
