- cause the webclient native library to be loaded from the
  NativeEventThread.  This eliminates many native thread safety
  assertions.

M webclient/classes_spec/org/mozilla/webclient/impl/wrapper_native/CurrentPageImpl.java

- Initialize the dom on the NativeEventThread

- Get the dom on the NativeEventThread

M webclient/classes_spec/org/mozilla/webclient/impl/wrapper_native/EventRegistrationImpl.java

- remove unnecessary synchronized block.
