The new print out includes skips and has prefixed sections so you can
grep to find things like transforms chosen on each frame.

currently threading is internal to libvpx so thread safety is unneeded
in libgtest -- visual studio builds already operate in this way as they
do not have pthread.h available by default.
this removes an unconditional link to libpthread using $(extralibs)
should libvpx require it.

Tests resolutions of 8, 10, 16, 18, 32, 34, 64, 66 to exercise the
border conditions, as well as non-SB aligned sizes.

Optimized the quantization function by making it a two-pass
process. The first pass does a quick checking of the transform
coefficients against the base ZBIN, and only keep the good
enough set of coefficients for quantization. A skipping
check is added. If all coefficients are within the base ZBIN, no
quantization is needed. The second pass is the actual quantization
pass, which only processes the coefficient subset determined
in first pass. This reduces the computation. Furthermore, an
alternitive method is used for large transform size, which often
has sparse nonzero quantized coefficients.
Overall, the encoder speedup is about 4%. The quantization function
itself gets 20% faster.

This commit makes use of dual fdct32x32 versions for rate-distortion
optimization loop and encoding process, respectively. The one for
rd loop requires only 16 bits precision for intermediate steps.
The original fdct32x32 that allows higher intermediate precision (18
bits) was retained for the encoding process only.
This allows speed-up for fdct32x32 in the rd loop. No performance
loss observed.

This seems to only be used in the encoder. Also remove an empty wrapper
file that contained forward declarations for this function, but didn't
actually define any actual functions.

The error happened because of vp8_decrypt_cb typedef redefinition in both
treereader.h and vp8dx.h. Removing typedef from vp8dx.h in favor of raw
function pointer declaration.

This allows code calling the library can choose an arbitrary
encryption algorithm.
Decoder control parameter VP8_SET_DECRYPT_KEY is renamed to
VP8D_SET_DECRYPTOR, and now takes an small config struct instead
of just a byte array.

quiets a warning on every file; the preference is to use a 64-bit
compiler, which is readily available at and above this version.

vp9_default_inter_mode_probs was being accessed with a different type
than it was defined with. Ensure that its declaration is included
prior to its definition.

All elements of this table are equal to 252, so replace it with a
single constant VP9_COEF_UPDATE_PROB.

The encoding time for bus at CIF goes from 661s to 625s. This commit
also enabled unit test of sad8x4/4x8 in sad_test.cc.

Avoid calling decode_block, inverse transform/add in the block is
a skip block for SBs smaller than 8x8 and intra-coded SBs.
