Implement `MessagePort` and `MessageChannel` along the lines of the DOM classes of the same names. `MessagePort`s initially support transferring only `ArrayBuffer`s. Thanks to Stephen Belanger for reviewing this change in its original form, to Benjamin Gruenbaum for reviewing the added tests in their original form, and to Olivia Hugger for reviewing the documentation in its original form.
