Replace the `.sync*` macros on `Future[Ack]` with functions #517

Related to issue #515 — the .sync* macros have been low level implementation details, exposed because they are useful as shortcuts.

However those macros are very unstable, error prone and I am not convinced that they bring performance benefits.

They should be replaced with plain functions.

If we see a performance regression in Observable.flatMap or scanEval, where I believe such macros are used, then we can keep using macros internally. But I doubt it, the macros themselves being a performance optimization that was done without proof.
