Move internal class Whitebox to API

[GoogleCodeExporter]

In the context of mocking, the Whitebox class of Mockito is incredibly useful.

For example, with Java 7, it got harder to mock java.io.File because of the 
following method:

final boolean isInvalid() {
        if (status == null) {
            status = (this.path.indexOf('\u0000') < 0) ? PathStatus.CHECKED
                                                       : PathStatus.INVALID;
        }
        return status == PathStatus.INVALID;
    }

To get around the problem that this method will always yield PathStatus.INVALID 
we have to set the private field path.

At the moment I'm tempted to say no.
