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>
