inotify: use a decorator instead of dispatching calls

inotify: do not defer inotify events processing Doing a part of the event processing and deferring the rest is a bad habit: it complexifies the code, and it does not respect event ordering! Moreover, there is already a timeout handling, so that inotify events are only processed when a treshold is exceeded: there is no requirement to delay anymore the events processing.

inotify: do not recurse in handle_timeout(): call it explicitely, not in scan() When in handle_timeout, scan() is called when a repertory is created/modified. But the first line of scan calls handle_timeout. This had the consequence of calling recursively handle_timeout: * several calls to read_events (but only the first one retrieves events) * every time that an event is queued for a deferred action, the next time that scan() is called, handle_timeout is called, the event queue is treated, even if all the events haven't been read/queued yet. This could lead to inconsistencies
