This change is necessary for the frame-based multithreading
implementation.
Since the postproc occurs in this call, vpxdec was modified to time around
vpx_codec_get_frame()

Multiple decoders were getting allocated per frame.
If the decoder crashed we exitted with out freeing
them and the next time in we'd allocate over.

This fix removes the allocation and just has 8
boolcoders in the pbi structure

Updated/added a few cases of temporal patterns,
and some changes to the encoder settings.

If the decoder crashes and returned an error before it set up
block offsets but after it set up frame buffers.   We had a
problem decoding the next keyframe because the block offsets
were never set.

Adjusts some of the qualification thresholds in mfqe to eliminate
artifacts due to wrong decisions. Besides, a new qualification
criteria is used to disable mfqe if the quality of the previous
frame is itself not too good.

The denoiser function was modified to reduce the computational
complexity.

1. The denoiser c function modification:
The original implementation calculated pixel's filter_coefficient
based on the pixel value difference between current raw frame and last
denoised raw frame, and stored them in lookup tables. For each pixel c,
find its coefficient using
    filter_coefficient[c] = LUT[abs_diff[c]];
and then apply filtering operation for the pixel.

The denoising filter costed about 12% of encoding time when it was
turned on, and half of the time was spent on finding coefficients in
lookup tables. In order to simplify the process, a short cut was taken.
The pixel adjustments vs. pixel diff value were calculated ahead of time.
    adjustment = filtered_value - current_raw
               = (filter_coefficient * diff + 128) >> 8

The adjustment vs. diff curve becomes flat very quick when diff increases.
This allowed us to use only several levels to get a close approximation
of the curve. Following the denoiser algorithm, the adjustments are
further modified according to how big the motion magnitude is.

2. The sse2 function was rewritten.

This change made denoiser filter function 3x faster, and improved the
encoder performance by 7% ~ 10% with the denoiser on.

Replace DECLARE_ALIGNED_ with vpx_memalign()

DECLARE_ALIGNED (__declspec(align())) does not work as intended when
used on class data members:

Data in classes or structures is aligned within the class or structure
at the minimum of its natural alignment and the current packing setting
(from #pragma pack or the /Zp compiler option)

For videos with big static background(such as video conferencing
clips), the mode decision was biased to ZEROMV in order to
obtain a stable background. The percentage of ZEROMV on last
frame was used to predict if there is static area in current frame,
and checking already-encoded neighboring macroblocks' motion
vectors to make sure the local area has low motion.
