Rename fsleep because the current name breaks the pattern of the first
letter being a unit (and it is not 'femto' here). Let's add the proper
unit again and add a suffix to the function which will hopefully be a
bit more explanatory. To give some time until all users are converted,
introduce a fallback define which will go away later.
