This CL addresses a long standing TODO to implement transferring ports from JS to Java.

Note that this is the last piece of MessageChannel puzzle. With this, we can consider basic implementation done. There is a missing feature to implement posting messages to frames given with their names, but this has other dependency.

We can now start further testing, optimization and refactorings.
