Allow intra-only frame in svc to also work
in bypass (flexible-svc) mode.
Added unittest for the flexible svc case.
And fix the gld_fb_idx for (SL0, TL1) in bypass/flexible
mode pattern in the sample encoder: force it to be 0
(same as lst_fb_idx), since the slot is unused on SL0.

Add encoder control to disable feature to increase Q
on overshoot detection, for CBR. Default (no usage
of the control) means the feature is internally enabled.
Add the control to the sample encoders, but keep it
disabled as default (set to 0, so feature is on).

Force all upper spatial layers to be key frame if the base layer is key.
Mode only works for inter-layer pred=off and non-flexible mode.
Add flag to write out bitstream for each spatial layer in example
encoder.

Also write it to opsnr.stt when internal stats is enabled.
Removed some redundant code in vpxenc.c and vp9cx_set_ref.c

Write height and width of top layer to ivf header in SVC.
vpxdec Can't decode it correctly when output is y4m.

Add update_buffer_slot to SVC API to allow for refreshing
any of the 8 reference buffers. Remove frame_flags from
the struct.
Remove svc tests from vp8 build.

This adds the following command line options to
vp9_spatial_svc_encoder test app:
--drop-frame=<arg> Temporal resampling threshold (buf %)
--tune-content=<arg> Tune content type default, screen, film
--inter-layer-pred=<arg> 0 - 3: On, Off, Key-frames, Constrained

Refactor the scene detection for 1 pass cbr to allow the
scene detection to be checked once per superframe (on the base layer),
using the full resolution sources.
If scene change is detected: check for re-encoding due to
large overshoot for all spatial layers withing the superframe.
Add speed feature to control the re-encode step.
Keep the re-encode step on for now.
Small change in nonrd_pickmode to remove the possible skip of golden
reference for SVC, when the high_source_sad is set for the superframe.
Change only affects SVC encoding with screen-content mode enabled.

The control is set by log2 of number of threads (such that the number of
tiles is the same of number of threads).
Thus it should be log2(num_threads) instead of (num_threads >> 1).

When writing out stream for spatial layer N,
make sure to include all spatial layers up to N.
Fixes an issue with the streams when frame dropping occurs.

Add VP9E_SET_SVC_INTER_LAYER_PRED to disable inter layer (spatial)
prediction.
0: prediction on
1: prediction off for all frames
2: prediction off for non key frames
Bump up ABI version.

SVC frame dropper: modify the logic to allow for individual
spatial layers to drop. This removes the constraint that all
upper spatial layers must drop when a given spatial layer drops.
Add a flag to the pkt to indicate whether a spatial layer is
encoded or dropped. This is needed for applications that enable
this feature (frame dropping for SVC).
For a current spatial layer, if its previous spatial layer is
dropped, then disable certain features for that layer:
inter-layer prediction, base_mv, partition_reuse, copy partition.
Also add the constraint to never drop a spatial layer if its
base layer is a key frame.
Updates to sample encoder (vp9_spatial_svc_encoder) and the
SVC datarate unittests to properly handle frame dropping.
Bump up ABI version.

Static analysis does not recognize that output_rc_stat guards
the usage of window_size. Clears this warning:
The right operand of '>' is a garbage value
if (frame_cnt > (unsigned int)rc.window_size) {
set_rate_control_stats sets window_size to 15. Zeroing it
just introduces another static analysis warning.
Change-Id: Ieee7b81a385f986e42189101cfa39279e519b368
This should be taken care of by parse_superframe_index but
the static analysis is not recognizing it because it depends
on 'marker' which is read from the bitstream.
Clears a static analysis warning:
The right operand of '*' is a garbage value
rc.layer_encoding_bitrate[layer] += 8.0 * sizes[sl];
Change-Id: I8ee48a98f907bc7b46869fd27a351f33e2e7de71
Print error messages as they are encountered. This was the default
behavior.
Removes a static analysis warning regarding the use of strncat:
Null pointer argument in call to string length function
As this is the only use of strncat in the library, remove it and the
associated public function.
Change-Id: Id55305c5a4d65f11da88c3a2203ff824200f526f
sl was passed to set_frame_flags_bypass_mode, triggering
an uninitialized variable warning. Inside the function it
is only used as a local variable.

Only affects 2 temporal layer case.
Modified the flags for 2 temporal layers to make
top layer (top spatial, top temporal) a non-reference
frame, conistent with the 3 TL case.
Add mismatch check to the datarate test of changing
svc pattern on the fly, which is test for 2 temporal
layers.
This re-applies the change: 254e2f5501,
