This patch splits the implementation of util.debuglog into a
separate file and explicitly initialize it during pre-execution
since the initialization depends on environment variables.
Also delays the call to `debuglog` in modules that are loaded during
bootstrap to make sure we only access the environment variable
during pre-execution.

Do not put the `.stop()` and `.drain()` methods on the
`MessagePort` prototype if we are going to remove them
later on anyway.

Instead of passing the payload for Workers directly to `.onmessage`,
perform something more similar to what the browser API provides,
namely create an event object with a `.data` property.
This does not make `MessagePort` implement the `EventTarget` API, nor
does it implement the full `MessageEvent` API, but it would make
such extensions non-breaking changes if we desire them at
some point in the future.
(This would be a breaking change if Workers were not experimental.
Currently, this method is also undocumented and only exists with
the idea of enabling some degree of Web compatibility.)

Remove setting of a 'close' event handler on MessagePort through the use
of an `.onclose` property. We don't use this convention anywhere else in
our codebase for 'close' events, this feature is undocumented, and we
don't test it.

Do not print debug messages that indicate that a stdio stream
has drained; because `util.debuglog()` uses `console.log`, which
in turn uses stdio streams, this would otherwise have lead to an
endless loop.

- Move `setupProcessStdio` which contains write access to
the process object into `bootstrap/node.js`
- Move `MessagePort`, `MessageChannel`, `ReadableWorkerStdio`,
and `WritableWorkerStdio` into `internal/worker/io.js`
- Move more worker-specific bootstrap code into
`internal/process/worker_thread_only` from `setupChild`
in `internal/worker.js`, and move the `process._fatalException`
overwrite into `bootstrap/node.js` for clarity.
