2 pass only change to calculation of rd mult based on Q.
Make a small adjustment based on frame type and also
replace adjustment based on iifactor with an one based
on the ambient GF/ARF boost level.

Also fix multi arf bug / issue.

Overall these change give an slight improvement in ssim
but hurt psnr a little.

Use a weaker filter for second level arf frames.
Average gain across all sets and metrics ~0.3%

Remove code for arnr_type which is no longer
supported in VP9 which always uses a centered blur.

Re-factor and some cleanup.

* Replace max_step_search_steps with constant MAX_MVSEARCH_STEPS
* Fold (reduce_first_step_size + speed > 5) into reduce_first_step_size
  replacing uses of reduce_first_step_size that don't add the speed
  check with zero.

The y4m extension used is the same as the one used in ffmpeg/x264.
The patch is adapted from the highbitdepth branch.

Also adds unit tests for y4m header parsing and md5 check
of the raw frame data, as well as y4m writing.

vp9_rdopt is for making rd optimal mode decisions. vp9_rd is for all
other rd related routines. Anything used outside of making an rd optimal
decision belongs in rd.

Moved the threshold adjustment before reference flag checking,
which could set the threshold to INT_MAX for disabled reference
frame, and cause overflow if the adjustment is done after that.

Renamed updating_running_avg() to filter(). Extended function with the rest of
the filter procedure. Made all of the empirically-determined constants used in
VP8 into functions so they can be tweaked more easily.

As in VP8.

Currently, this parameter is set with the VP8E_SET_NOISE_SENSITIVITY flag.
The flag was not renamed so that we don't break the interface for webrtc. This
should probably be changed at some point in the future.

Add test code to turn multi-arf on and off depending
on group length and zero motion.

Changes to active max group length for mult-arf.

This commit added a speed feature to control the step_param used in
full pixel motion search. The intention is to reduced the search
steps for high speed real time coding.

Adapt the use of segmentation in AQ mode 2 based on
the ambient kf/arf/gf Q.

Disable segmentation where the rate per SB is very
low and overheads are likely to outweigh the benefits.

This patch reduces the -ve average metrics impact
of AQ mode 2 while allowing stronger 3 segment AQ
in some cases. Average improvement ~0.5-1.0%.
