Paul Wilkins 513f8e6814 Relax rate control for last few frames 
VBR rate control can become very noisy for the last few frames.
If there are a few bits to spare or a small overshoot then the
target rate and hence quantizer may start to fluctuate wildly.

This patch prevents further adjustment of the active Q limits for
the last few frames.

Patch also removes some redundant variables and makes one small bug fix.
