* calculates average QP as a float, providing slightly improved
ratecontrol if the first pass was CBR.
* fixes the reported QP if you set both b_stat_read and b_stat_write,
allowing 3 pass encoding (or just examination of the 2nd pass's stats)."

* all: Patch by Loren Merritt.
" This patch makes scene-cut detection based on the relative cost of I-frame
vs P-frame, rather than just on the number of I-blocks used.
It also makes the scene-cut threshold configurable.
This doesn't have a very large effect: Most scene cuts are obvious to
either algorithm. But I think this way is better in some less clear cut
cases, and sometimes finds a better spot for an I-frame than just waiting
for the max I-frame interval."
