Bug introduced in I930dced169c9d53f8044d2754a04332138347409. If
svc.number_temporal_layers == 1 and svc.number_spatial_layers == 1, the system
attempt to do spatial SVC. It no longer does that.

Also added reset_frame_stats()

Fixed reported vs warnings/errors.

For the primary arf in a group, if multiple arfs
are enabled and we were using arfs in the previous
group, then allow the second arf from the previous
group to be used as an additional reference.

This commit enables an adaptive transform size selection method
for speed -6. It uses largest transform size when the sse is more
than 4 times of variance, i.e., most energy is compacted in the
DC coefficient. Otherwise, use the default TX_8X8. It improves
the compression efficiency for rtc set of speed -6 by 0.8%, no
speed change observed.

This patch allows the encoder to skip the partition search for the
frame if it is an inter frame and only zero motion vectors have
been detected in the first pass. The partition size is directly
assigned according to the difference variance.

Borg tests show overall little performance changes in term of PSNR
(derf -0.027%, yt 0.152%, hd 0.078%, stdhd 0%). The worst case of
PSNR loss is -0.514% from yt. The best PSNR gain is 4.293% from yt.
The second pass encoding speedup for slideshow clips is 15%-40%.

C version and sse2 version, and off by default.
For the test clip used, the sse2 performance improved by ~5.6%

This commit enables a fast reference motion vector search scheme.
It checks the nearest top and left neighboring blocks to decide the
most probable predicted motion vector. If it finds the two have
the same motion vectors, it then skip finding exterior range for
the second most probable motion vector, and correspondingly skips
the check for NEARMV.

The runtime of speed -5 goes down
pedestrian at 1080p 29377 ms -> 27783 ms
vidyo at 720p       11830 ms -> 10990 ms
i.e., 6%-8% speed-up.

For rtc set, the compression performance
goes down by about -1.3% for both speed -5 and -6.

Bug introduced during multiple iterations on: I3831*

gf_group->arf_update_idx[] cannot currently be used
to select the arf buffer index if buffer flipping on overlays
is enabled (still currently the case when multi arf OFF).

This commit fixes the potential issue in the non-RD mode decision
flow that only checks part of the block to estimate the cost. It
was due to the use of fixed transform size, in replacing the
largest transform block size. This commit enables per transform
block cost estimation of the intra prediction mode in the non-RD
mode decision.

* changes:
  vp9cx.mk: move avx c files outside of x86inc block
  test.mk: remove renamed file

same reasoning as:
9f3a0dbb vp9_rtcd: correct avx2 references

these are all intrinsics, so don't depend on x86inc.asm

This patch reverts the previous revert from Jim and also add a
variable user_priv in the FrameWorker to save the user_priv
passed from the application. In the decoder_get_frame function,
the user_priv will be binded with the img. This change is needed
or it will fail the unit test added here:
https://gerrit.chromium.org/gerrit/#/c/70610/

This reverts commit 9be46e45.

vp90-2-15-fuzz-flicker.webm was renamed in:

Cosmetic patch only in response to comments on
previous patches suggesting a couple of name changes
for consistency and clarity.

like vpx_codec_decode(), vpx_codec_peek_stream_info() takes an unsigned
int, not size_t, parameter for buffer size

Change-Id: I4ce0e1fbbde461c2e1b8fcbaac3cd203ed707460

the max is 6. there are assumptions throughout the decode regarding
this; fixes a crash with a fuzzed bitstream
