fc1de713f5 systemd: bind udev control socket in systemd and split udev.service 
We should bind the udev socket from systemd, so we are sure
that the abstract namespace socket is always bound by a root
process and there is never a window during an update where
an untrusted process can steal our socket.

Also split the udev.service file, so that the daemon can be
updated/restarted without triggering any coldplug events.

fc416258f3 udevd: do not wrongly delay events for devices with swapped names 
Renaming network devices might delay events for the other device, which has
the same devpath in the meantime as the original event. Causing a delay until
the timout of the event is reached.

Look at the ifindex/devnum of the devices to check if they are really
the same devices.

c61eea9459 Add support for oom_score_adj 
/proc/<pid>/oom_adj has been deprecated (kernel v2.6.36) due to the
rework of the badness heuristic; oom_score_adj is the replacement.
Keep a fallback to the old interface for compatibility with older
kernels.

ebd189621f do not rename the database on device rename 
Harald Hoyer discovered some incorrect behavior while debugging
problems with network interface renaming:

Udev events might be queued for devices which are renamed. A new
device registered the same time may claime the old name and create
a database entry for it. The current rename logic would move over
this databse entry to the wrong device.

e.g. if eth0 should be eth3 and eth3 is waiting to be renamed,
eth0 was renamed to eth0_rename. The kernel would take eth0 as the name
for a new interface and this new eth0 could also become eth0_rename, if
the target name is also taken. To prevent this name clash, the
interfaces are now renamed to <src>-<dest> and the rename is logged.
