workers: basic event loop (#3828) * establish basic event loop for workers * make "self.close()" inside worker * remove "runWorkerMessageLoop() - instead manually call global function in Rust when message arrives. This is done in preparation for structured clone * refactor "WorkerChannel" and use distinct structs for internal and external channels; "WorkerChannelsInternal" and "WorkerHandle" * move "State.worker_channels_internal" to "Worker.internal_channels" * add "WorkerEvent" enum for child->host communication; currently "Message(Buf)" and "Error(ErrBox)" variants are supported * add tests for nested workers * add tests for worker throwing error on startup 2020-02-11 10:04:59 +01:00			`onmessage = e => {`
