set LIBVPX_RAND with --enable-vp9-postproc, previously only the vp8
config was checked. this fixes the build with --disable-postproc.

Assembly tests should clear system state, as we have no
expectation of proper system state in between test runs..

This is meant as a framework for testing that encode parms make it
through to the decoder.

This commit fixes a bug in the PICK_MODE_CONTEXT index for
horizontal partition case. The compression performance change
is less than 0.01% level, since most blocks are selected to
use square block size in RTC coding mode.

dqcoeff is set to be 0 on initialization. And set back to 0 after being
used everytime.

This commit explicitly uses the bit shift operation instead of
division for computing block variance.

The 8x8 DCT uses a fast version whenever possible.
There was a mistake in the checking code which
meant sometimes the fast version was used when it
was not safe to do so.

(cherry picked from commit fd05fb0c21e253b4d6f92d7e0b752850ff8ab188)

This commit refactors the choose_partitioning function. It removes
redundant memset calls and makes the encoder to calculate
variance value per block only when it is needed. It reduces the
average runtime cost of choose_partitioning by 60%. Overall it
reduces speed -6 runtime by 2-5%.

It is the first version of MFQE in VP9. There are a few TODOs included
in this version.
Usage: Add flag --enable-vp9-postproc to config the project.
In decoder, use flag --mfqe in the command line to enable
MFQE in postproc.
Note: Need to have key frame with low quality to see the effect of this
new patch. In my experiment, I fixed the qindex to 200 in key frame.
