inotify: Separate query sending logic from Server starting.

Use a decorator around the public statusquery method of Client:

start_server(query_to_server):
    try:
        query_to_server()
    except QueryFailed:
        [error recovery, inotify Server (re)starting]
        query_to_server()

This way, introducing a new xxxquery Client method is easy:
one has only to code the protocol part of xxxquery, ignoring errors,
and decorating it using start_server to handle server recovery
and (re)starts
