Implement Java <-> JS bindings.

Implemented invoke Java methods and fecth Java fields from JavaScript.
Java-side access native-JS objects is not supported. JavaScript-side
modification of JS objects is not supported.

The implementation uses NPAPI, which is simple, but less efficient.
Java abstraction is very much copied from original WebCore/bridge/jni,
except all JSC bindings are replaced by NPAPI.
