Expect Path instead of string for add_watch
Embed inotify_event data in Event
Temporarily remove name from event

Name handling is currently broken and events with a name will lead to
failure. This commit removes the broken code while I'm working on a fix
for the situation.
Fix representation of inotify_event
Improve formatting
Add internal event buffer to wrapper

This fixes the issue with directory events (i.e., events that have a
name). Support for the optional name is still not enabled, but at least
these events no longer cause a task failure.
Remove debug output
Fix broken handling, in case of multiple events
Re-add name field to Event
