Replace the raw poll() + global running/reload_rules flag dance with libuev. All four signals (SIGUSR1, SIGTERM, SIGHUP, SIGCHLD) are now handled via uev_signal_init() -- libuev uses signalfd internally so the handlers run in normal main-loop context, not async signal context. The SIGCHLD handler waitpid(-1, WNOHANG) reaps any subprocess (modprobe loads, rule RUN+= helpers) instead of the old SIG_IGN auto-reap trick. Synchronous waitpid() in modprobe_load() and run_program() still works because signalfd queues the signal -- it only reaches sigchld_cb on the next main-loop iteration. The netlink receive loop becomes uevent_cb() registered via uev_io_init(), with the receive buffer passed via the watcher's arg slot (avoids file-static state). ENOBUFS and EINTR/EAGAIN are still tolerated, any other recv() error still panic()s. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
