This is required in order to build libvpx on OS X Mavericks where gcc
compiler is deleted, clang (3.3) is the default now.

Using unmodified source files from gtest-1.7.0/fused-src folder.

When only upper-left 8x8 area has non-zero dct coefficients, we
could skip 1D IDCT for 9th to 32th rows to save operations. This
function is called when eob <= 34.

If the webm file did not have a Cues then vpxdec would fail
when creating a y4m file. If there is no Cues element print
out a warning and set fps to 30.

* changes:
  Renaming INTERPOLATIONFILTERTYPE to INTERPOLATION_TYPE.
  Adding VP9_FRAME_MARKER constant.

set_active_map()
set_roi_map()

The APIs need be implemented and tested later, to insure consistency
with VP9 codec internals

For consistency with idct function names. Renames:
  vp9_short_fdct4x4  -> vp9_fdct4x4
  vp9_short_walsh4x4 -> vp9_fwht4x4

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.

The encode_block for pass 1 takes simpler functionalities and can
save a few branches. The main reason is to make encode_block only
used after running rate-distortion optimization search in pass 2,
hence allowing dual buffer stack approach later.

Use a flag variable to determine if coded in inter mode, thus avoiding
multiple inter mode checks in super_block_yrd.
