For blocks at frame boundary, the selected block size sometimes needs
to be smaller than that was first given. This commit forces such block
size change only between square blocks, so as to avoid the potential
use case containing 32x16 + 16x8 + 16x8, for 1080p sequences.

Local test suggested no visible coding speed difference. Borg test
reveals no difference in terms of compression performance.

* changes:
  cosmetics: test.mk: sort source lists
  test.mk: fix test availability
  sad_test: (arm) fix vp9-only build
  cosmetics: sad_test: add a few comments

previously the scale functions would always be include regardless of the
CONFIG_SPATIAL_RESAMPLING setting.

about 15-20% over exsiting speed 7.

This commit removes a few arguments that are not used in the
non-RD mode decision.

Added fast HEX search while doing non-rd partition picking to
speed up the encoder.

Borg test(speed 7) on rtc set showed 1.8% overall PSNR loss.
Encoder speedup was 5% - 15% for different rtc clips.

In handle_inter_mode, the reference frames are set in refs buffer.
One can use refs buffer directly to avoid redundant fetch.
