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>

-
-                <para><command>systemd-cgtop</command> shows the top
-                control groups of the local Linux control group
-                hierarchy, ordered by their CPU, memory and disk I/O load. The
-                display is refreshed in regular intervals (by default
-                every 1s), similar in style to
-                <citerefentry><refentrytitle>top</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
-
-                <para>Resource usage is only accounted for control
-                groups in the relevant hierarchy, i.e. CPU usage is
-                only accounted for control groups in the
-                <literal>cpuacct</literal> hierarchy, memory usage
-                only for those in <literal>memory</literal> and disk
-                I/O usage for those in
-                <literal>blkio</literal>. <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
-                by default places all services in their own control
-                group in the <literal>cpuacct</literal> hierarchy, but
-                not in <literal>memory</literal> nor
-                <literal>blkio</literal>. If resource monitoring for
-                these resources is required it is recommended to add
-                <literal>blkio</literal> and <literal>memory</literal>
-                to the <varname>DefaultControllers=</varname> setting
-                in <filename>/etc/systemd/system.conf</filename> (see
-                <citerefentry><refentrytitle>systemd.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>
-                for details). Alternatively, it is possible to enable
-                resource accounting individually for services, by
-                making use of the <varname>ControlGroup=</varname>
-                option in the unit files (See
-                <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
-                for details).</para>
-
-                <para>To emphasize this: unless
-                <literal>blkio</literal> and <literal>memory</literal>
-                are enabled for the services in question with either
-                of the options suggested above no resource accounting
-                will be available for system services and the data shown
-                by <command>systemd-cgtop</command> will be
