This function initializes the predictor buffer pointers and
calculates reference motion vectors. It is only needed in the settings
of inter frame coding. Hence removing it from the key frame coding
branch in rtc_use_partition.

This function is deprecated after the re-design of partition search
that runs big block size, then four-way split, followed by
rectangular block sizes. This commit removes the related functions.

The function rd_pick_reference_frame can be deprecated. Its use was
subsumed by the adaptive motion search control.

Removes certain cases of feedback of active_worst_quality,
and removes it from the RATE_CONTROL structure. Now active
worst quality is expected to be computed locally in the
q picking function during the encode.
Making temporal filter strength depend on avg_frame_qindex
rather than on active_worst_quality actually improves
performance esp. for yt.
derf: +0.038%
yt: +0.359%

In real time encoding, we enable encode_breakout to make encoding
fast. A speed feature "use_encode_breakout" is defined to set
encode_breakout thresholds for different speeds.
However, currently, static_thresh is an encoder option. The encode_
breakout can be turned off if user sets static_thresh=0 specifically.
The rtc set borg test result: (need to set --static_thresh=1)
speed -5, psnr loss -3.543%;
speed -4, psnr loss -2.358%;
speed -3, psnr loss -0.771%.
Encoding speed test:
speed -5, 11% - 60% speedup;
speed -4, 5.5% - 28% speedup;
speed -3, 0.8% - 7% speedup.

Some parameter changes and fixes on one-pass rate control.
derfraw300 is now only 10% below 2-pass speed 0 rate control.

This CL changes libvpx to call a function when a frame buffer
is needed for decode. Libvpx will call a release callback when
no other frames reference the frame buffer. This CL adds a
default implementation of the frame buffer callbacks. Currently
only VP9 is supported. A future CL will add support for
applications to supply their own frame buffer callbacks.
