Bug 907 - Refine DummyDispatchThread (DDT) Handling: Proper OO integration in RegisteredClass; Safe DDT Post/WaitForReady handling and error cases ; ...

Proper OO integration of DDT in RegisteredClass
  - DDT is optional to RegisteredClass[Factory],
    i.e. NEWT without DDT and DummyWindow with DDT.

  - Using native type DummyThreadContext per DDT
    passed as DDT handle to java referenced in RegisteredClass

  - Passing DDT handle to related native methods,
    if not null use DDT - otherwise work on current thread.
    The latter impacts CreateDummyWindow0 and DestroyWindow0.

Safe DDT Post/WaitForReady handling and error cases ; ...
  - Wait until command it complete using a 3s timeout
  - Terminate thread if errors occur and throw an exception

Discussion: DDT Native Implementation

Due to original code, the DDT is implemented in native code.
Usually we should favor running the DDT from a java thread.
However, since it's main purpose is _not_ to interact w/ java
and the native implementation has less footprint (performance and memory)
we shall be OK w/ it for now - as long the implementation IS SAFE.
