The logic for spatial resizing is done after the Q is selected for the
frame. This causes a problem that the Q we select for the (resized)
key frame may be based on a different resolution than the frame we
will encode.
This fix is to ensure that, when resize is on, the selected Q is still
based on the resolution of the frame to be encoded.

Compares the sum of differences between the input block and the averaged
block. If they differ too much the block will not be filtered. Negligible
perfomance hit.

Add PRIVATE macro for adding private_extern directive for yasm
to hide global symbols. This is only enabled if -DCHROMIUM is used
with YASM.
Also fixed a small problem with rtcd_defs.sh to guard TEMPORAL_DENOISING.

This extends the denoiser to work for temporally scalable
coding.
I believe this also fixes a very rare but really bad bug in the original
implementation.

After a key frame encoding, the frame type could change while
filtering is still going on. Pass the frame type as parameter to the
loopfilter function and don't read it from common storage.
vp8cx_set_alt_lf_level has to be done before packing the stream.
Currently alt_lf_level is not used so there hasn't been any visible
problem here.

Resolution changes in calls to vpx_codec_enc_config_set() would cause
a memory leak due to failing to release the lookahead and alt ref
buffers.

Change If4321cc5 fixed a bug caused by forward declarations not being
kept in sync across C files, resulting in a function call with the
wrong arguments. The commit moves the affected function declarations
into a header file, along with the other symbols from encodeframe.c
that were being sloppily shared.

Removes all runtime initialization of global data. This commit is a
squashed version of the following series cherry-picked from master.
This is necessary because of a change that was merged to the tester
that depends on the scaler being moved to the RTCD framework, which
is a worthwhile thing to include in Eider anyway.

Besides imposing a performance penalty at startup in most
configurations, these relocations break the dynamic linker for
native Fennec, since it does not support them at all.

Race was introduced by https://gerrit.chromium.org/gerrit/15563.
If loopfilter related config params were changed between frames, or
after a KEY frame, there could be a mismatch between encoder's and
decoder's recontructed image. In worst case, when frame buffers are
reallocated because of a size change, the loopfilter could
do an invalid data access (segmentation fault).
Fixes:
Sync with the loopfilter before applying any encoder changes in
vp8_change_config().
Moved the loopfilter synching to the top of
encode_frame_to_data_rate() so that it's done before any alteration of
the encoder.

Look for changes in the codec's configured w/h instead of its active
w/h when forcing keyframes. Otherwise calls to vp8_change_config()
will force a keyframe when spatial resampling is active.

When producing an invisible ARF, the time stamp counters aren't
updated since the last time stamp is seen by the codec twice. The
prior code was trapping this case with refresh_alt_ref, but this isn't
correct for other uses of the ARF. Instead, use the show_frame flag.

Adds logic to disable mfqe for the first frame after a configuration
change such as change in resolution. Also adds some missing

This change added a motion search skipping mechanism similar
to what we did in second pass. For a macroblock that is very
similar to the macroblock at same location on last frame,
we can set its mv to be zero, and skip motion search. This
improves first-pass performance for slide shows and video
conferencing clips with a slight PSNR loss.

This issue likely doesn't appear in the unmodified encoder, but
sufficient hacking on the mode selection loop can expose it.

Produce the token partitions on-the-fly, while processing each MB.
Context is updated at the beginning of each frame based on the
previoud frame's counters. Optimally encoder outputs partitions in
separate buffers. For frame based output, partitions are concatenated
internally.
Limitations:
- enabled just in combination with realtime-only mode
- number of encoding threads has to be equal or less than the
number of token partitions. For this reason, by default the encoder
will do 8 token partitions.
- vpxenc supports partition output (-P) just in combination with
IVF output format (--ivf)
Performance:
- Realtime encoder can be up to 13% faster (ARM) depending on the number
of threads and bitrate settings. Constant gain over the 5-16 speed
range.
- Token buffer reduced from one frame to 8 MBs
Quality:
- quality is affected by the delayed context updates. This again
dependents on input material, speed and bitrate settings. For VC
style input the loss seen is up to 0.2dB. If error-resilient=2
mode is used than the effect of this change is negligible.
Example:
./configure --enable-realtime-only --enable-onthefly-bitpacking
./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480
--target-bitrate=1000 --token-parts=3 --static-thresh=2000
--ivf -P -t 4 -o strm.ivf tanya_640x480.yuv
