APIv3: Allow to write application binding
This enable a binding version 3 to declare no API. This is used to start a job that will will run after initialisation. The tutorial tuto-app1 shows how. Run it with: afb-daemon --binding tuto-app1.so A further option could be add to close stdin even if running in foreground, as it was the case before.
