ReduceNoiseImage parallel patch

[zehruela]

Hi, I made some changes in effect.c:ReduceNoiseImage function to support multi threading execution (using OpenMP). For large files the new code achieves improvements in performance around 30%.

We can't use the patch as is. OpenMP must be enabled with pragma's so ImageMagick can compile if OpenMP is not enabled or available. Refactor your patch and repost and we will get it into the ImageMagick distribution.

I'll post the refactored version ASAP.
