A couple of minor modernizations: 1. Don't unnecessarily export functions we don't call outside of machined.c 2. Use cleanup logic for the manager object. 3. Propagate errors properly from manager_new(). So far if sd_event_new() returns EMFILE/ENFILE for some reason we would have logged that as log_oom(), which isn#t right, really. 4. Handle SIGTERM/SIGINT cleanly. It's easy, and prettier then letting the kernel just abort us. It also makes it possible to valgrind machined properly.
