97a86c5b13 fix a bug in multithreaded encoding with active_map enabled
Added the initialization of the pointer to active map. Also added the
same logic for cyclic refresh in mbrow encoding threads.

e0cf330cde vp8 fast quantizer sse2 optimizations for eob.
Changed the end of block computation to use pmaxw.  Removed
additional pushing and popping of registers that was not needed.

cb9698951c fix uninitialized read in encode breakout
Change I3430820 performed an uninitialized read when
encode_breakout == 0, since the sum and sse wouldn't be set:

   if(x->encode_breakout)
       VARIANCE_INVOKE(..., get16x16var)(..., &sum, &sse);
   if (cpi->active_map_enabled && x->active_ptr[0] == 0) {
       ...
   } else if (sse < x->encode_breakout)

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.

7c03a1c308 adjust RDMULT for UV plane in quantization RDO
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.
