Bugfixes:
-* the running hwdb seems not to pick up updated database files without
- an explicit: udevadm control --reload
* enabling an instance unit creates pointless link, and
the unit will be started with getty@getty.service:
interate through that to bring down complexity from O(n^2) to O(n)
when loading units
-* Move backlight and random-seed into /var/lib/systemd
-
* If we try to find a unit via a dangling symlink generate a clean
error. Currently we just ignore it and read the unit from the search
path anyway.
* udev:
- remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
- move to LGPL
- - unify utf8 validator code with shared/
- kill scsi_id
- add trigger --subsystem-match=usb/usb_device device
