local_find returns a promise because that's what the cache contains.

This was a Lwt.t before. This is an attempt to make sure that effects are caught by Eio_main.
`Lwt_stream` is difficult to migrate to other concurrency libraries because of its vast API and its many usecases. Its usage in `Eliom_comet` can easily be changed to a callback-based approach. This might increase performances as well.
Add a new callback-based API, `Eliom_bus.register`, which avoids using `Lwt_stream` internally. `Eliom_bus.stream` is re-implemented against the register API. `Eliom_bus.original_stream` is not re-implemented yet.
`Eliom_comet.register` and `Eliom_bus.register` propagate errors from the server using an `option` type. `Eliom_bus` ensures that the callback won't be called again after being called with `None`. This "end of stream or error" signal was present before through `Lwt_stream`, which could propagate the `Closed` exception. In both `Eliom_comet` and `Eliom_bus`, the callbacks are released when the channel closes to allow memory to be collected.
Implement the callback-based API that can be used with values of type [Eliom_comet.Channel.t] that can be passed from the server.
- Remove `Eliom_bus.stream` and `Eliom_bus.original_stream`
