Sean Owen bfa614b127 SPARK-4022 [CORE] [MLLIB] Replace colt dependency (LGPL) with commons-math 
This change replaces usages of colt with commons-math3 equivalents, and makes some minor necessary adjustments to related code and tests to match.

Author: Sean Owen <sowen@cloudera.com>

Closes #2928 from srowen/SPARK-4022 and squashes the following commits:
