When started with -c (the default when keventd is the device manager), gate the pidfile on the kernel's uevent_seqnum having been stable for 200ms. Up to now ready signaling with the pidfile was done right after coldplug() triggered the kernel to re-emit events, but before uev_run() had drained any of them, so <pid/keventd> really only meant "listening on netlink". With the gate, services that depend on <pid/keventd> can now assume /dev is populated and persistent symlinks are live. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
