This commit adds the logic for segmentation map initialization and
disable temporal update of segmentation map when error-resilient
mode is on. It fixes the enc/dec mistmates (release build) and
assertions(debug) when both aq-mode and error-resilient are on.

Remove the vp9_ prefix from vp10 file names.

Change-Id: I513a211b286a57d6126fc1b0fbfd6405120014f1

This commit folks the VP9 and VP10 codebase and makes libvpx
support VP8, VP9, and VP10.

Change-Id: I81782e0b809acb3c9844bee8c8ec8f4d5e8fa356

Use system_state.h in vpx_dsp and remove unneeded includes of
vp9_systemdependent.h.

Some places are using the unoptimized variance function. This was never
intended and does not fit into the optimization framework.

Change-Id: Id96238407aad03b0ffd4a46cd183555a026daedc

subpel functions will be moved in another patch.

Change-Id: Idb2e049bad0b9b32ac42cc7731cd6903de2826ce

With the sad functions, and hopefully the variance functions soon,
moving to the vpx_dsp location, place the defines used in the
reference C code in a common location.

This patch greatly increase the strength of AQ1.

Visual tests show strong gains on many clips but their is a big
hit on psnr.

SSIM is more mixed with some winners and losers.

In defining the Q deltas for segments in AQ1 use a rate
ratio rather than a q ratio.

Change-Id: Id31a74fcf2b7e55437e42a51c21b3cbcb57028d4

Make the midpoint variance used in AQ mode 1 segmentation
depend on the overall complexity of the frame in two pass.

Change-Id: I452814ec57f7a32352e41bb250e78066abe952dd

Add an additional restriction to bit/complexity based
segmentation based on spatial variance.

Only lower Q when both the number of bits spent
in the initial encoding pass and the spatial complexity are
below a threshold. This will prevent the low Q segments
being used just because there is a surfeit of bits.

Small metrics gains especially opsnr.
derf ~0.2% std-hd ~0.3%

Further patch to restructure AQ mode 1.

Change-Id: I566452a033d047a49a40441a7be24690ea69412d

This is the first of a series of patches to restructure and
improve AQ mode 1 (variance based AQ).

Change-Id: Idcf693131a3ea2459dcfd957a54a65b971fa4a2a

Removed redundant weighting function tied for AQ1 from first
pass code.

Improvment in baseline AQ1 results:-
Derf  opsnr +0.142% SSIm +0.258%
YT  opsnr +0.173% SSIm +0.3%

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.

clamp() wants an int, round returns a double, warning! Too bad we can't just use lrint.

Change-Id: I9c08289dde742fac0d673df8559a1892edcd1bc7

Removed the comment "// __asm emms;" from all calls
to vp9_clear_system_state.

Aq 1 only updates segment map on kf and arf and
only uses 3 segments. With these settings AQ1 is
+ for most clips in SSIM but negative in psnr.
However, the penalty in PSNR is much less than
previously.

Old version aq1 average results for std hd
-20.899% psnr, -5.809% SSIM
New version aq1 for std hd
-3.57% psnr, +1.23% SSIM

Aq2 Now uses only 2 segments and rd.
This mode is still slightly negative for most clips on
psnr and SSIM but seems to have a much bigger visual
impact on several problem clips than aq mode 1.

Old results for std hd:
-2.578% psnr, -1.151% SSIM
New results for std hd:
-1.561% psnr, -0.85% SSIM

Also avoid using floating-point operations when adaptive quantization is
disabled.

This should be similar to what x264 does with --aq-mode 1.
It works well with clips like parkjoy and touhou
(http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv).
At low bitrates, the segmentation signaling overhead may negate the
benefits of this feature.

(PGW) Default changed to feature OFF to allow provisional merge.
