Get coverage to work

Measure lib/* coverage based on test execution in addition to spec.
Test and spec changes are for satisfying generic rules below.

 * simplecov requires target code to be loaded before invoking
   SimpleCov.start.
 * Invoke SimpleCov.start once. Multiple call works if use_merging =
   true (default) but unnecessarily complex.

Report from 'rake coverage' at this point.

Add explicit test/unit dependency

This change needs consultation with CRuby guys.

 * CRuby trunk and 2.2.0-preview1 needs this but is this intentional
   change?
 * If this change only needs for developers living with CRuby trunk?

FWIW I once heard that this is only needed by the ruby command built
from svn repo but unnecesarry in general ruby installation.

We keep this option for backward compatibility.
Maybe, there is no user who wants to disable this option.
We will remove related code in the future.
