vp9: Add flatness metric to cyclic refresh setup.
For screen-content with aq-mode = 3: identify spatial
flat superblocks in the setup stage and don't mark them as
candidates for refresh. Spatially flat blocks are already
removed from refresh at a later stage in the encoding (in pick_mode),
but doing this at the setup stage of cyclic refresh (before encoding)
allows refresh to more quickly hit the text areas. Only drawback is
an extra source variance calculation for a set of superblocks on
each frame.
Adjust the refresh rate: lower it to reduce overshoot since
more texture areas are hit faster with this change.

Another case is where speed for base layer is different than that of

frame will be encoded at max_q.

this is to avoid scene change detection on cases like large

vp9: Disable re_encode_overshoot feature for speed >= 6.
For real-time screen content mode: for speed >= 6 disable
the re_encode_overshoot feature. This means for speed >= 6
the Q and rate control is reset on slide changes based on
the scene/slide detection and the current Q (and not on a
first pass encoded frame at current Q).
This reduces encode time on slide changes, but may be less
accurate in deciding when to reset/max-out the Q.

Handle partition cost better in RD search
Take partition cost into consideration during rectangular partition

Compression change is neutral. Encoding speed can be a little faster
at low quality settings. With QP=55 at speed 0, average speed up over
15 midres sequences is about 2.7%.
