This commit enables the non-RD mode decision coding flow to
adaptively apply partition search in non-refresh frame, when the
collocated block in previous frame suggests there might be a motion
activity. It refactors the update_state_rt() function to support
buffer swap of mode_info struct, thereby unifying the encoding
stage across various non-RD coding modes.
It provides 5% compression performance gains in speed -6 for rtc
test set, at about 12% speed slow down.

Fix so that vp9_update_segment_aq() will use the correct (i..e, chosen)
encoding mode (from ctx struct) in update_state.

This commit allows the recursive non-RD partition search to early
terminate sub search tree when the cumulative rate-distortion is
already above the best available.

This commit added a speed feature to make the logic of calculating
skip_recode on a block level more explicit. This also enable the
feature to be enabled at speed 5 where the previous logic is too
conservative, help gain back the lost speed for --rt(-5).

There were a few conflicts between the new non-RD partition search
and recent clean-up patches, which were not caught by git control.
This commit fixed these issues.

This commit takes out the if statements on using adaptive motion
search flag. This feature is automatically enabled in non-RD mode
decision flow for variable partition types search.

This patch fixed WebRTC Issue 3020: "Uninit error at
vp8_mbpost_proc_down_xmm". The first 8 values in d were not initialized,
but was accessed. This patch fixed c code as well as mmx and sse2 code.

This commit enables a recursive partition type search for non-RD
mode decisions. It allows the encoder to choose variable block
sizes in a 64x64 block based on rate-distortion modeling.
It improves speed -6 coding efficiency for rtc set by 2.4%. Most
of the gains come from 32-40dB range, where many sequences gain
about 5% to 20%. Local tests suggest there is no speed change.
