Add event debugging to libinput_post_event

Browse source 
Print the type of event when it is queued up internally. This makes it a lot
easier to associate evdev events with the libinput event queued up and does
not depend on the caller calling libinput_dispatch().

Since this should only be used during development, hide it behind an if 0.
