The function has evolved over time, now only calls vp9_rtcd(), so this
commit removes the function and changes to call vp9_rtcd() directly.

Adds a speed 8 to VP9 where only the nearestmv (0 mv) is searched.
This seems to be about the same speed as vp8 speed 5.

Adds a new speed feature to disable inter modes based on a mask for
each blocksize.

Adds code for having lower complexity motion search methods
in nonrd pick mode function, even though speed 7 still uses DIAMOND
search for now.

Also uses HEX search for speed 6 rather than FAST_HEX which improves
psnr by 0.56% without any noticeable speed drop (tested on gipsmotion).

There was a bug in the previous code that if GOLDEN was better than
LAST neither would be used. LAST would get turned off due to superior
GOLDEN quality then all GOLDEN modes would get skipped.

The commit change to use partitions sizes directly from last frame
for frames directly where last frame selects partitions sizes based
on coding efficiency.

On --rt --cpu-used=-5, the change hurts compression by 4% but reduces
encoding time by ~20%

Change-Id: Ia68665e5c8489b7bfcf5fac7768332fba88928e6

Adds a method for determining a fixed size partition based on
variance of a 64x64 SB. This method is added to rtc speed 6.
Also fixes a bug in rtc_use_partition() and includes some
refactoring related to partitioning search, and some cosmetics.

Currently compared to speed 5, the coding efficiency of speed 6
is -19% and that of speed 7 is -55%, in cbr mode.

Moves the existing speed 6 to speed 7 and adds an

speeds 6 and 7 in both speed and coding efficiency.
Also includes some minor fixes/adjustments.

In good quality mode motion search, the best matches are normally
found after searching in a large area. In real time mode, to make
encoding fast, a center-biased fast HEX search is used, which
converges quickly most of the time. A 4-point diamond search is
also carried out as the following refining search, which gives more
precise results, and maintains good motion search quality.

At speed 5, the borg test on rtc set showed an overall PSNR loss of
0.936%. The encoding speed gain is 4% - 5%.

Prior to this commit, both encoder and decoder reset mode/mv info from
previous frame in error resilient mode to ensure bitstreams are able to
decode when there is loss of frame in decoder side. However, this is
not necessary. This commit changed to remove the reset, so encoder can
continue to use mode/mv/partition information from previously encoded
frame without affecting decodeablilty under loss of frame.

In rtc coding mode, the encoder is running non-RD mode decision. It
does not need dual buffer swap as was the case in the RD mode. This
commit initializes the internal buffer pointers outside the block
coding loop for rtc mode.

rectangular block sizes. This commit removes the related functions.

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.

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.

Aq 1 only updates segment map on kf and arf and
only uses 3 segments. With these settings AQ1 is
+ for most clips in SSIM but negative in psnr.
However, the penalty in PSNR is much less than
previously.

Old version aq1 average results for std hd
-20.899% psnr, -5.809% SSIM
New version aq1 for std hd
-3.57% psnr, +1.23% SSIM

Aq2 Now uses only 2 segments and rd.
This mode is still slightly negative for most clips on
psnr and SSIM but seems to have a much bigger visual
impact on several problem clips than aq mode 1.

Old results for std hd:
-2.578% psnr, -1.151% SSIM
New results for std hd:
-1.561% psnr, -0.85% SSIM

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.
