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>

- <literal>gettys</literal> are

- already used by some other subsystem
- (for example a graphical login) this
- kind of activation will not be
