  vpx_memset16: drop unnecessary local
  vpx_memset16: quiet signed/unsigned warning

The artifact occurs periodically when VP9 denoiser is on and
refresh_golden_frame happen. When refresh_golden_frame happen,
we should copy the frame buffer instead of swapping the pointers.

Small code cleanup. consec_zeromv refresh threshold
does not need to be computed for every super-block.

No change in behavior.

Use the existing VP9_SET_SVC control to set the
first spatial layer to encode.

Since we loop over all spatial layers inside the encoder, the
setting of spatial_layer_id via VP9_SET_SVC has no relevance.
Use it instead to set the first_spatial_layer_to_encode,
which allows an application to skip encoding lower layer(s).

Change only affects the 1 pass CBR SVC.

When configured with high bit detpth enabled, the 8bit quantize
function stopped using optimised code. This made 8bit content
decode slowly. This commit re-enables the SSSE3 optimisations.

See issue 1051. 6 bits is fairly arbitrary but at least allows writing
delta Q values that are fairly normal in other codecs. I can extend to
8 if people want full range, although I personally don't have any need
for that.

The resolution check fixs the issue which resets resize_pending
unnecessarily and causes not-bitexact with previous one-step version.

When configured with high bit detpth enabled, the 8bit quantize

Temporary fix to denoiser when dynamic resizing is on.
 -Reallocate denoiser buffers on resized frame.
 -Force golden update on resized frame.
 -Don't denoise resized frame, and copy source into denoised buffers.

For screen-content mode, with frame dropper off, put a limit
on how low encoder buffer can go.

Under hard slide changes, the buffer level can go too low and then
take long time to come back up (in particular when frame-dropping
is not used), which will affect the active_worst and target frame size.

Dynamic resizing now support two-steps scaling: first go down to
3/4 and then 1/2. This feature is under a flag which controls the
switch between two-steps scaling and one-step scaling (1/2 only).

This is more a proof of concept than anything else. The problem here
isn't so much how to code it, but rather where to place the resulting
code. All intrapred DSP code lives in vpx_dsp, so do we want the vp10
specific intra pred functions to live there, or in vp10/?

See issue 1015.

The x86 simd expects this. Identical alignment can be found in vp9
and vp10 also. Fixes crashes on 32bit x86 systems.
