c63fc881e1 Correct q_low and q_high limits for the recode loop
Corrected the initial Q range limits for the recode loop
to reflect the current allowed range for the frame.

In experimental work on constrained quality this bug was
causing unnecessary recodes.

This patch adds a weighting factor on RDMULT for UV blocks. The change
has an overall gain about 0.5% based on ssim, between 0.1 and 0.2% by
psnr numbers.

cec6a596b5 Change to inter_minq table.
The inter_minq table controls the range of quantizers available
for a particular frame in two pass relative to a max Q value.

The changes reduces the range somewhat. The effect of this
was a small increase (0.3% average) in psnr for the test set
but it should also help encode speed somewhat for higher
quality modes as it will reduce the number of iterations in the
recode loop.

The change damps the range of quantizers available locally
within a section of a clip and should therefore help keep quality
more uniform. If there is systematic overshoot or undershoot the
range can shift gradually to accommodate. However, there is
some increased risk of overshoot or undershoot against the target
bit rate in VBR mode and this risk will be more pronounced for short
clips.

c3bbb29164 Improve MV prediction accuracy to achieve performance gain
Add vp8_mv_pred() to better predict starting MV for NEWMV
mode in vp8_rd_pick_inter_mode(). Set different search
ranges according to MV prediction accuracy, which improves
encoder performance without hurting the quality. Also,
as Yaowu suggested, using diamond search result as full
search starting point and therefore adjusting(reducing)
full search range helps the performance.

9c8ad79fdc Set refresh_alt_ref_frame on keyframe encode.
On a keyframe alt ref and golden are refreshed.  The flag was
not being set and so on the frame after a keyframe, motion
search would occur on the alt ref frame.  This is not necessary
because the alt ref frame identical to the last frame in this
scenario.

Handle corner case where a forward alt-ref frame is put
directly after a keyframe.

This function was never called in a context expecting a return value,
the return value was always a constant, and the !CONFIG_MULTITHREAD
path didn't have a return statement, which caused a compiler warning.
This patch changes the function to return void instead.

373f5c3144 Bad cost tables used in ARNR filtering.
The use of incorrect mv costing tables in the ARNR sub-pel
filtering code led to corruption of the altref buffer in some cases,
particularly at low data rates.

The average gain from this fix is about 0.3% but there are a few
extreme cases where nasty and visible artifacts manifested and
for these few data points the improvement is > 10%.

ef2f27f10e make rdmult adaptive for intra in quantizer RDO
This intends to correct the tendency that VP8 aggressively favors rate
on intra coded frames. Experiments tested different numbers in [0, 1]
and found 9/16 overall provided about 2-4% gains for all-intra coded
clips based on vpx-ssim metric. The impact on regular encoded clips
is much smaller but positive overall. Overall impact on psnr is also
positive even though very small.

0a49747b01 quantizer: fix assertion in fast quantizer path
The fast quantizer assembly code has not been updated to match the new
exact quantizer, which was made the default in commit 6adbe09.
Specifically, they are not aware of the potential for the coefficient
to be scaled, which results in the quantized result exceeding the range
of the DCT. This patch restores the previous behavior of using the
non-shifted coefficients when in the fast quantizer code path, but
unfortunately requires rebuilding the tables when switching between the
two.

513f8e6814 Relax rate control for last few frames
VBR rate control can become very noisy for the last few frames.
If there are a few bits to spare or a small overshoot then the
target rate and hence quantizer may start to fluctuate wildly.

This patch prevents further adjustment of the active Q limits for
the last few frames.

Patch also removes some redundant variables and makes one small bug fix.
