Adjust some parameters for cyclic refresh for low bitrates.
Reduce motion threshold and boost factor for second segment,
for low bitrates, at low resolutions for now.
This is to reduce the rate fluctuation/frame dropping that occurs
at these low bitrates.

Changes to active maxq calculation in two pass.
Some initial experiments into discounting dead zone
formating bars and intra skip blocks (common in some
types of animation and graphics) in the calculation of
the active max Q for each ARF/GF group.
TODO: check for vertical formating bars and validate the
horizontal bar at the bottom edge of the image.
As expected, this change as it stands, does not make much
difference for the natural videos in the std-hd and derf sets.
However, for the yt and yt hd set there is a significant rise
in the average PSNR with overall PSNR and SSIM remaining
neutral.
The mean rise for the YT-HD test set was > 6%. This is mainly
because the change allows Q to drop further on titles and
other graphics sections where spending a small number of
extra bits gives a sharp rise in PSNR.

Enable more split modes for animated content.
For content that is identified as likely to contain some
animation or graphics content, increase the availability
of split modes for good quality speeds 1-3.
On a problem test animation clip this improves metrics
results by about 0.25 db and makes a noticeable difference
visually. It also causes a small drop in file size (~0.5%) but
a rise in encode time of about 5-6% at speed 2.
For more normal content it should have no effect.
