In the distant past this was used to distinguish between
armv5/6/7 targets when building the assembly files. The
project has not supported armv5/6 for a long time.

For row_mt=1, when mi->skip is set to 1 after parse based on
eobtotal for that partition, dqcoeff and eob need to be restored
as recon_partition doesn't increment these pointers for skip cases

Move the setting to just before the inter-mode loop,
as for screen content the value may change due
to reset of segment.
No change in behavior except for screen-content.

In the calculation of boost for key frames, increase number
of frames to be scanned based on the content nature.

The frame next to scene cut frame does not usually have
a high second ref useage. Thus the sec ref useage of the
frame next to scene cut frame is tested against a
threshold for scene cut detection.
With this change scene cut detection is improved for
contents where genuine scene cuts were being missed.

Reduce the number of group_idx initialization.
Initialize the center to the median of the data group.

Add speed feature for real-time to always force
SMOOTH filter for subpel motion. Can be useful in some
cases for noisy content or high motion at low bitrate.
Also some speedup in avoiding the checking of two filters.
Keep it off always for now.

This CL removes the extra floating math in tune=psnr, I will add
clear_system_state calls in tune=ssim in the next cl.

fixes a deadlock with an odd number of threads that go from < number of
tiles to >. the previous calculations were out of sync so going from
e.g., 8 tiles to 2 with 3 threads would result in scheduling only 2
workers, but thread_loop_filter_rows() would expect 3.

The Wiener variance output has been sorted prior to the clustering,
which allows to directly use the uniform sampling as the initial
center points. It avoids empty cluster situations when the samples
are heavily distributed at two far ends and leave the middle empty.

With switching to clang-7.0.1 we got new warnings. With this change the
warnings are back to 0 for all configurations (excluding warnings in
third_party)
