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>A number of different components are involved in the
-                system boot. Immediately after power-up, the system
-                BIOS will do minimal hardware initialization, and hand
-                control over to a boot loader stored on a persistent
-                storage device. This boot loader will then invoke an
-                OS kernel from disk (or the network). In the Linux
-                case this kernel now (optionally) extracts and
-                executes an initial RAM disk image (initrd) such as
-                <citerefentry><refentrytitle>dracut</refentrytitle><manvolnum>8</manvolnum></citerefentry>
-                which looks for the root file system. After the root
-                file system is found and mounted the initrd hands over
-                control to the system manager (such as
-                <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>)
-                stored on the OS image which is then responsible for
-                probing all remaining hardware, mounting all necessary
-                file systems and spawning all configured
-                services.</para>
-
-                <para>On shutdown the system manager stops all
-                services, unmounts all file systems (detaching the
-                storage technologies backing them), and then
-                (optionally) jumps back into the initrd code which
-                unmounts/detaches the root file system and the storage
-                it resides on. As last step the system is powered down.</para>
-
-                <para>Additional information about the system boot
-                process may be found in
-                <citerefentry><refentrytitle>boot</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para>

-                <title>System Manager Bootup</title>
-
-                <para>At boot, the system manager on the OS image is
-                responsible for initializing the required file
-                systems, services and drivers that are necessary for
-                operation of the system. On
-                <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
-                systems this process is split up in various discrete
-                steps which are exposed as target units. (See
-                <citerefentry><refentrytitle>systemd.target</refentrytitle><manvolnum>5</manvolnum></citerefentry>
-                for detailed information about target units.) The
-                boot-up process is highly parallelized so that the
-                order in which specific target units are reached is not
-                deterministic, but still adheres to a limited amount
-                of ordering structure.</para>
-
-                <para>When systemd starts up the system it will
-                activate all units that are dependencies of
-                <filename>default.target</filename> (as well as
-                recursively all dependencies of these
-                dependencies). Usually
-                <filename>default.target</filename> is simply an alias
-                of <filename>graphical.target</filename> or
-                <filename>multi-user.target</filename> depending on
-                whether the system is configured for a graphical UI or
-                only for a text console. To enforce minimal ordering
-                between the units pulled in a number of well-known
-                target units are available, as listed on
-                <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para>
-
-                <para>The following chart is a structural overview of
-                these well-known units and their position in the
-                boot-up logic. The arrows describe which units are
-                pulled in and ordered before which other units. Units
-                near the top are started before units nearer to the
-                bottom of the chart.</para>
