MATH-1630: Runtime switch between JDK and CM implementations of the methods defined in "java.lang.Math".
...
Default is to use the CM implementations in order to retain previous behaviour.
When using the JDK implementations, some unit tests fail (on Java 8).
Class "AccurateMath" was moved to "o.a.c.math4.core" package.
[Unit tests for that class were not moved because they depend on "legacy" classes.]
