Yu Watanabe 29b5eb5adf udev-rules: make import_property_from_string() take sd_device 
Also, this makes the function return negative errno, though its
return value is always ignored.

Yu Watanabe 480ecb7d28 udev: use sd_device for udev_event.dev_db 
Also, this adds sd_device_unref for the object in udev_event_free()
for safety and readability of code.

Yu Watanabe faae64fa3d udevd: increase default number of workers 
The uevent handling in udevd is not cpu hungry.
So, let's increase the default number of workers per cpu.
This decrease the number of queued uevents.

Without this commit (children_max is 16 on my laptop)
```
$ journalctl -b -u systemd-udevd.service | grep reached | wc -l
1544
```
With this commit (children_max is 30 on my laptop)
```
$ journalctl -b -u systemd-udevd.service | grep reached | wc -l

Yu Watanabe eca195ec23 udevd: wait 3 seconds before killing worker processes 
During boot process, many worker processes are forked and killed.
To decrease cycles of forking and killing worker, let's wait
3 seconds before killing workers. If new uevent or inotify event
comes within the delay, the killing porcess will be cancelled.

Yu Watanabe da14313418 udevd: drop redundant logic of receiving uevent 
If there exists pending uevents, then sd-event invokes uevent handler.
So, it is not necessary to receive the next uevent in inotify event.

Yu Watanabe 7af1c7808b udev-event: do not store unused devnum 2018-10-31 09:29:51 +09:00
Yu Watanabe d4a95a952e udev-event: check whether device has devnum before calling udev_node_remove() 
This fixes a bug in 'remove' event handling, which was introduced by
eb1f9e30ec, as 'devnum' variable may
not be initialized.
