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.

Silence signed/unsigned mismatch warnings by adding casts where
ts_number_layers does not match the sign of the variable to which
it is being compared.

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.

The functionalities of set_offsets() are subsumed in later
set_partitioning() and rtc_use_partition() functions, hence removed.

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%

Two convolve functions were optimized for AVX2:
1. vp9_filter_block1d16_h8
2. vp9_filter_block1d16_v8
vp9_filter_block1d16_v8 was optimized for AVX2 by reducing the number of
loop strides by half, two strides were processed in parallel.
vp9_filter_block1d16_v8 was also optimized in the same way also some of the
loads were being done outside of the loop and by that preventing redundant
loads.
This Optimization gives 43% function level gain and 1.3% user level gain.
Now can be compiled in Windows

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.
