Add Java 6 additions to Double, Enum, Float, and String.
I rewrote the documentation for Double, Enum, and Float, but the "code" is the
same as harmony's. I rewrote the String code and wrote some tests to ensure
that a malicious Charset can't subvert String immutability.
I've also extracted the Android-specific bits of StringTest (which weren't
testing String at all) and brought back the latest harmony StringTest.java.
(The Class and Package changes are just to placate our API comparison tools.)
