Removes the redundant dst pointers from vp9_build_inter_predictors_sb{y,uv}
and the remaining mb specific functions.

Merge "Removing get_segment_id function and using existing vp9_get_pred_mb_segid." into experimental

Wherever there are real pixels available before falling back to use
assumed values 127 and 129.

This also make DC_PRED for i4x4 consistent with DC_PRED for larger
blocks.

First in a series of commits moving the framebuffers pointers to
per-plane data, so that they can be indexed numerically rather than
by name.

Removed some unused legacy code relating to GF activity.

Use the common sb functions instead.

Remove the unnecessary _s_ from their names, and add a new
vp9_recon_sb() that calls the y and uv variants.

Similar to the prior change that removed the rounding from non-SPLITMV
modes. Improves quality by a similar amount (Additional +0.087% on derf)

Further simplification of mvref search to return
only the top two candidates. Distance weights removed
as the test order reflects distance anyway.

slightly worse results for faster encodes

This experiment has failed to give much benefit but
does add complexity so deprecated.

As we are no longer able to sort the candidate
mvrefs in both encoder and decode and given
that the cost of explicit signalling has proved
prohibitive, it no longer makes sense to find more
than 2 candidates.

This patch:

Modifies and simplifies add_candidate_mv()

Removes the forced addition of a 0 vector in the
MAX_MV_REF_CANDIDATES-1 position (in preparation
to reducing MAX_MV_REF_CANDIDATES to 2).

Re-orders the addition of candidates slightly.

This actually gives small gains (circa 0.2% on std-hd)

A subsequent patch will remove NEW_MVREF experiment,
reduce MAX_MV_REF_CANDIDATES to 2 and remove distance
weights as these are implicit now in the order.

Adjustments take heavier account of the frame near a kf
in deciding boost and limit the total number that can contribute.
Also adjusted the minq calculations such that in most cases we
generate a smaller key frame.
Modified the code that accounts for how static the sequence is and
added some adjustment based on image size. This is still very
crude but smaller images tend to behave better with a larger
delta between KF Q and other frames than larger image formats.
Changes give sizable gains in overall PSNR  on all the test sets but the
biggest gains (~3%) were on the std-hd set.
The gains were smaller for SSIM but still significant.
Average PSNR results are mixed because this metric can very easily
be altered by having a very good / lossless coding of one or two frames.
Some of the YT and YT-HD clips in particular have blank lead ins and
allowing lossless coding of these appears to make a big difference to
average PSNR but it reality does not help much at all.
