* Avoid unnecessary type erasure
* Prune unused/duplicate fields from struct rdcost_block_args
* Make struct rdcost_block_args a local

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.

SSE for a 64x64 block with 3 planes can go as high as 3*2^28. So left
shift by 4 may overflow 32 bit int.

The affect on quality was minimal. Less than .1%, various sets
yt ( +.15%), derf (-.1%), hd ( -.1% ), std hd(-.15%)...
The affect on speed of encode at speed -5 was substantial ( ~3% ).

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 funtion initializes buffer pointers and first stage motion vector
prediction. It will be needed by both regular rate-distortion
optimization loop and the non-RD mode decision. Hence move its
declaration in vp9_rdopt.h

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

The previous implementation stops motion vector prediction test when
the zero motion vector appears for the second time. This commit fixes
it by simply skipping the second time check on zero mv and continuing
on to next mv candidate.
It slightly improves stdhd in speed 2 by 0.06% on average. Most static
sequences are not affected. A few hard ones, like jet, ped, and riverbed
were improved by 0.1 - 0.2%.
