Committed by Ivan Molodetskikh

Commit Message

Only cap overflow if it's actually a danger.

In the normal case (when we're not in danger of wasting bits
 because we have not used enough), soft_limit is negative.
As a result, log_soft_limit was being set to -1.
Normally this is fine, since we then compare it against
 (log_scale_pixels - log_q_exp), the log of the estimated number of
 bits that will be used, which is usually positive.
However, when the number of pixels is very small (e.g., for a 1x1
 video), it is possible for (log_scale_pixels - log_q_exp) to be
 negative, and we will try to enforce the limit anyway.
This results in very bad things (integer overflows) when we try.

This commit also corrects a parentheses error that was introduced
 when porting the original implementation to rav1e (the division by
 margin should happen before the multiply, which can also cause
 overflows).
