The core motion estimation fucntions all return sad now consistently.
The only exception is vp9_full_pixel_diamond(), however the core diamond
and refining search routines called from vp9_full_pixel_diamond() also
return SAD. If variance of pred error + mv cost is desired it must be
calculated explicitly outside these functions. For very fast encoding,
hopefully this will eliminate some redundant computations.

Also suggests reimplementing FAST_HEX with the vp9_pattern_search
framework. It is not exactly the same as the existing FAST_HEX, but
performance is slightly better and speed is very similar. Enables
removing a lot of duplicate code.

Usage of encode_b_args is unnecessary because encode_block_pass1() doesn't
use them. That's why optimize_init_b() call is also not required.

Removed the comment "// __asm emms;" from all calls
to vp9_clear_system_state.

Flipping arf on and off too often is hurting some clips.
This change makes no difference for 50-75% of our test
clips but helps some by a big margin. (eg. std-hd crew
by 6% and one of the YT and YT-hd clips by 14%)

Average improvements for 2 pass, speed 2 (psnr,ssim)
are as follows:-

derf  0.165%, 0.210%
yt  1.210%, 1.464%
yt-hd 1.189%, 1.471%
std-hd 1.031%, 0.886%

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.

Inlcudes a number cleanups:
1. Moves the one-pass pre-encode parameter setting functions
to vp9_ratectrl.c
2. Deprecates per_frame_bandwidth in RATE_CONTROL structure
3. Removes target_bandwidth in cpi structure since it is not used.
4. Various renaming of functions

There is no bit-stream change in 2-pass, one-pass cbr and one-pass
vbr modes.

Fixes rate control partially in one-pass non-cbr case to achieve a
bitrate close to the one desired. Previous version was way off at
the high bitrate end.

Also includes several one-pass rate control cleanups and refactoring.

On derfraw300, one-pass encoding is now 19% off from two-pass speed
0 encoding, down from 35%.

Added a constant to represent the minimum KF boost
rather than using the magic number 2000 in the code.

Includes a few fixes and clean-ups that adds the ability
to use alt-ref frames in one-pass mode.
Whether alt-refs are actually used or not is controlled by a
macro USE_ALTREF_FOR_ONE_PASS in vp9_firstpass.c.

This first cut seems to improve derf by 15+% in 1-pass mode.
But further experiments with parameters are underway.

The sum of squared mv components can go beyond int range for large
 input resolution. This commit changed the type to int64 to avoid
overflow.

Applies an upper limit on burst bitrate for any
frame. This is to insure that typical encodes for YT
do not produce frames that are so large that they
risk stalling HW implementations. Such frames
could also cause playback problems in SW.

For now the limit is set at 250 bits per MB for 1080P
and larger (with the 1080P limit used for smaller frames).

Setting maxQ, constant quality mode or targeting a
very high bandwidth will have precedence over this limit.
