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.

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.

Function encode_rtc_frame_internal() and encode_frame_internal() only
differed by a couple of speed features, this commit relocation those
difference into the setup of speed features and merged two functions
into one to remove duplication.
It also fixed a subtle bug super_fast_rtc was used before it was
initialized.

This commit added a logic to prevent the inter_filter type from being
changed if the default interp_filter mode is not switchable. Also, it
sets the default interp_filter to BILINEAR at very and super fast rtc
encoding modes

--rt --cpu-used=-5 uses the progressive rtc mode
--rt --cpu-used=-6 uses the new super fast rtc mode

In this new mode, the size range is strictly determined by the min
and max partition size in neighborhood blocks.
Niklas720 encoding time at cpu-used -5 goes from 56250ms to 50676ms,
a 10% reduction.

This patch only works if the video is a width and height that are both
a multiple of 32.. It sets every partition to 16x16, and does INTRADC
only on the first frame and ZEROMV on every other frame. It always does
does the largest possible transform, and loop filter level is set to 4.
Was ~20% faster than speed -5 of vp8
Now 20% slower but adds motion search ( every block ), nearest, near
and zeromv
The SVC test was changed because - while this realtime mode produces
bad quality albeit quickly, it isn't obeying all the rules it should
about which frames are available.

This commit deprecates the use of best_mv from encoding and bit-stream
writing stages. It hence removes the definition from MACROBLOCKD.

This commit setups a test framework for real-time coding. It enables
a light motion search for non-RD mode decision purpose.

Calculate the skip_coeff as part of the encode process, rather than
checking the eobs after the fact with another pass.

This commit allows encoder to compare the SAD cost associated with
the best motion vector predictor, per frame. If one reference frame
has this cost more than 4 times of the best SAD cost given by other
reference frames, skip NEARESTMV, NEARMV, ZEROMV mode check of this
reference frame.
This setting is turned on in speed 2 and above. Compression quality
change in speed 2:
derf -0.014%
yt -0.097%
hd -0.023%
stdhd 0.046%
It reduces the speed 2 runtime of test sequences:
pedestrian_area_1080p 4000 kbps 310763 ms -> 303595 ms
bluesky_1080p 6000 kbps 259852 ms -> 251920 ms
