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.

add ClearSystemState() to reset MMX registers avoiding corrupting
subsequent tests.

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.

Looks like test code.

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.

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.

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