group error checking at the top followed by allocations, setup then
decode.

Making partition read/write logic more clear.

Change-Id: I1981e90327257d37095567c62d72a103cda1da33

replaces use of cur_tile_mi_(row|col)_(start|end) by VP9_COMMON, making
it less stateful and more reusable for parallel tile decoding

Change-Id: I1df09382b4567a0e5f4434825d47c79afe2399be

replace VP9D_COMP usage with the (slightly) more targeted
VP9_COMMON/MACROBLCKD structures.

Adding these functions to encapsulate tx_type check. Changing TX_TYPE to
int to match the declaration in vo9_rtch.h.

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.

It should be only a check based on the block type (inter vs intra), not on
the mode value.

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.
