ICE-1593 Handling thread interrupts in Java

- Added Ice.BackgroundIO property to perform all IO in a non-user
  thread. This makes Ice for Java interrupt safe. This is implemented
  by the QueueRequestHanbler.
- EndpointHostResolver now uses an executor instead of a thread.
- Added java/demo/Ice/interrupt and java/test/Ice/interrupt.
- Made several changes that must be ported to C++ & C#.
  - InvocationTimeout exceptions can hang forever.
  - Connection establishment is always asynchronous.
  - RequestHandler.requestTimeout and asyncRequestTimeout have been
    renamed to requestCancel and asyncRequestCancel.
