Verify two sun.* classes against OpenJDK 8u121-b13.

sun.* was generally forgotten in the update from OpenJDK8u60 to
8u121-b13.

This CL covers:

NameService:
 - Add missing Android-change marker.
 - Tweak a change marker in InetAddress to be more consistent.

VerifyAccess:
 Only some of the methods in this class are used, and those are only
 used by MethodHandles.
 - integrate upstream change to isTypeVisible().
   The upstream change is
     http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/c44179bce874
   It was made for OpenJDK 8u77-b03 but was forgotten in Android's
   update from OpenJDK 8u60 to 8u121-b13.
 - because isTypeVisible() is unused on Android / dead code, also
   comment out that method as well as the others that are unused
   on Android.

After this CL, the only thing left to verify in sun.* is one small
change in FileChannelImpl.
