Isolation of udev code from remaining systemd
This commit is a first attempt to isolate the udev code from the remaining code base. It intentionally does not modify any files but purely delete files which, on a first examination, appear to not be needed. This is a sweeping commit which may easily have missed needed code. Files can be retrieved by doing a checkout from the previous commit: git checkout 2944f347d0 -- <filename>

- <title>Description</title>
-
- <para><filename>systemd-suspend.service</filename> is
- a system service that is pulled in by
- <filename>suspend.target</filename> and is responsible
- for the actual system suspend. Similar,
- <filename>systemd-hibernate.service</filename> is
- pulled in by <filename>hibernate.target</filename> to
- execute the actual hibernation. Finally,
- <filename>systemd-hybrid-sleep.service</filename> is
- pulled in by <filename>hybrid-sleep.target</filename>
- to execute hybrid hibernation with system
- suspend.</para>
-
- <para>Immediately before entering system suspend
- and/or hibernation
- <filename>systemd-suspend.service</filename> (and the
- other mentioned units, respectively) will run all
- executables in
- <filename>/usr/lib/systemd/system-sleep/</filename>
- and pass two arguments to them. The first argument
- will be "<literal>pre</literal>", the second either
- "<literal>suspend</literal>",
- "<literal>hibernate</literal>", or
- "<literal>hybrid-sleep</literal>" depending on the
- chosen action. Immediately after leaving system
- suspend and/or hibernation the same executables are run,
- but the first argument is now
- "<literal>post</literal>". All executables in this
- directory are executed in parallel, and execution of
- the action is not continued before all executables
- finished.</para>
-
- <para>Note that scripts or binaries dropped in
- <filename>/usr/lib/systemd/system-sleep/</filename>
- are intended for local use only and should be
- considered hacks. If applications want to be notified
- of system suspend/hibernation and resume there are
- much nicer interfaces available.</para>
-
- <para>Note that
- <filename>systemd-suspend.service</filename>,
- <filename>systemd-hibernate.service</filename> and
- <filename>systemd-hybrid-sleep.service</filename>
- should never be executed directly. Instead, trigger
- system sleep states with a command such as
- "<literal>systemctl suspend</literal>" or
- similar.</para>
-
- <para>Internally, this service will echo a string like
- <literal>mem</literal> into
- <filename>/sys/power/state</filename>, to trigger the
- actual system suspend.</para>
