Title: several fixes to scala.concurrent.util.Duration

- add test cases (migrated from Akka sources)
- add overflow checking (will throw IllegalArgumentException instead of
giving wrong results)
- make string parsing more precise when giving >100days in nanoseconds
- make method signatures more precise in retaining FiniteDuration
throughout calculations
- fix mul/div of infinities by negative number
- add Ordering for Deadline (was accidentally left out earlier)
