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><command>systemd-analyze</command> may be used
- to determine system boot-up performance of the current
- boot.</para>
-
- <para><command>systemd-analyze time</command>
- prints the time spent in the kernel before
- userspace has been reached, the time spent in the
- initial RAM disk (initrd) before normal system
- userspace has been reached and the time normal system
- userspace took to initialize. Note that these
- measurements simply measure the time passed up to the
- point where all system services have been spawned, but
- not necessarily until they fully finished
- initialization or the disk is idle.</para>
-
- <para><command>systemd-analyze blame</command> prints
- a list of all running units, ordered by the time they
- took to initialize. This information may be used to
- optimize boot-up times. Note that the output might be
- misleading as the initialization of one service might
- be slow simply because it waits for the initialization
- of another service to complete.</para>
-
- <para><command>systemd-analyze plot</command> prints
- an SVG graphic detailing which system services have
- been started at what time, highlighting the time they
- spent on initialization.</para>
-
- <para>If no command is passed <command>systemd-analyze
- time</command> is implied.</para>
