To make sd-device properly usable for all programs we need to provide an API for the "action" field of an event, it's one of the most relevant ones, and it was so far missing. This also adds sd_device_get_seqnum(), which isn't that interesting, except for generating pretty debug output, which we use it ourselves for. This also makes device_new_from_stat_rdev() public, as it is truly useful, as we can see in our own uses of it, and I think is fairly generic to show up in the public APIs.
