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).

rather than die_codec(). calling any api functions with an uninitialized
codec context is undefined. this avoids a crash in a call to
vpx_codec_error_detail().

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

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).
