Improve the libvpx encoder test driver
The encoder initialization is called in EncodeFrame(). Therefore,
in the unit tests, the set control is done when video->frame() is 1.
This didn't cause problem since current tests mainly test lag_frame
> 0 case, or no encoding option that needs to allocate memory before
1st frame is used. If use lag_frame = 0 and encoding multiple tiles,
the unit tests crash. The issue is fixed by doing the initialization
before encoding frames.

Fix test to call clear system state in convolve_test.
Assembly tests should clear system state, as we have no

Adds a test to make sure encoder parms get to decoder.
This is meant as a framework for testing that encode parms make it
through to the decoder.

Fix PICK_MODE_CONTEXT index in non-RD coding mode
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.

Allow for 4x4 prediction blocks for key frame, speed 6.
For key frame under variance source partition: 4x4 prediction blocks
may be selected when variance of 8x8 block is very high (threshold is set fairly high for now).
Testing on some RTC clips shows this helps to reduce some ringing artifacts on key frame.
Encoded key frame size increases about ~10%. Key frame PSNR increases about ~0.1-0.2dB.

Prevent decoder from using uninitialized entropy context.
If decoding starts with intra-only frame, there is a possibility
of using uninitialized entropy context, what leads to undefined

Corrected optimization of 8x8 DCT code
The 8x8 DCT uses a fast version whenever possible.
There was a mistake in the checking code which

Refactor choose_partitioning computing scheme
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%.

Multiframe Quality Enhancement(MFQE) in VP9.
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.
