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>

-                is a service that collects disk usage patterns at boot
-                time. <filename>systemd-readahead-replay.service</filename>
-                is a service that replays this access data collected
-                at the subsequent boot. Since disks tend to be
-                magnitudes slower than RAM this is intended to improve
-                boot speeds by pre-loading early at boot all data on
-                disk that is known to be read for the complete boot
-                process.</para>
-
-                <para><filename>systemd-readahead-done.service</filename>
-                is executed a short while after boot completed and signals
-                <filename>systemd-readahead-collect.service</filename>
-                to end data collection. On this signal this service
-                will then sort the collected disk accesses and store
-                information about them disk in
-                <filename>/.readahead</filename>.</para>
-
-                <para>Normally, both
-                <filename>systemd-readahead-collect.service</filename>
-                and
-                <filename>systemd-readahead-replay.service</filename>
-                are activated at boot so that access patterns from the
-                preceding boot are replayed and new data collected
-                for the subsequent boot. However, on read-only media
-                where the collected data cannot be stored it might
-                be a good idea to disable
-                <filename>systemd-readahead-collect.service</filename>.</para>
-
-                <para>On rotating media, when replaying disk accesses
-                at early boot
-                <filename>systemd-readahead-replay.service</filename>
-                will order read requests by their location on disk. On
-                non-rotating media, they will be ordered by their
-                original access timestamp. If the file system supports
-                it
-                <filename>systemd-readahead-collect.service</filename>
-                will also defragment and rearrange files on disk to
-                optimize subsequent boot times.</para>
