fmemopen is not preferred during fuzzing.
Removed all file operations.
Removed need for allocating a different input buffer.
data buffer is appropriately incremented and passed directly to decoder
This will also test input being sent in an unaligned buffer to the library.
Removed read_frame function and did the required parsing inline.

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.

Instead of calling get_vpx_decoder_by_name(), derive
decoder interface directly.
This will avoid dependecy on tools_common and hence any potential
updates needed to build fuzzer, when tools_common uses functions
defined in a different file
With this dependency removed, fuzzer no longer needs to enable examples
when building vpx_dec_fuzzer binaries

As thread count is now randomized, serial and threaded modes can be
combined to a single binary.
With this change, threads takes values between 1 to 64 and tests both
single thread and multi-thread variants of the decoders

vpx_dec_fuzzer.cc can be built with clang++ to generate fuzzer binary

any of the 8 reference buffers. Remove frame_flags from
the struct.

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.

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.
