Merge OpenJDK 8 java.net (part 2)
Partial import of upstream jdk8u60 that does not introduce behavioural
differences:
* Remove unused imports
* Remove unused private fields
* Adding final modifier to some private fields
* Update copyright header
* Use of generics
* Cosmetic changes
This also imports upstream change to remove NetUtils, which does not
change behavior for Android as we does not use SecurityManager.
No functional change.
