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>The <filename>/etc/machine-id</filename> file
-                contains the unique machine id of the local system
-                that is set during installation. The machine ID is a
-                single newline-terminated, hexadecimal, lowercase 32
-                character machine ID string. (When decoded from
-                hexadecimal this corresponds with a 16 byte/128 bit
-                string.)</para>
-
-                <para>The machine ID is usually generated from a
-                random source during system installation and stays
-                constant for all subsequent boots. Optionally, for
-                stateless systems it is generated during runtime at
-                boot if it is found to be empty.</para>
-
-                <para>The machine ID does not change based on user
-                configuration, or when hardware is replaced.</para>
-
-                <para>This machine ID adheres to the same format and
-                logic as the D-Bus machine ID.</para>
-
-                <para>Programs may use this ID to identify the host
-                with a globally unique ID in the network, that does
-                not change even if the local network configuration
-                changes. Due to this and its greater length it is
-                a more useful replacement for the

-
-                <para>Note that the machine ID historically is not an
-                OSF UUID as defined by <ulink
-                url="http://tools.ietf.org/html/rfc4122">RFC
-                4122</ulink>, nor a Microsoft GUID. Starting with
-                systemd v30 newly generated machine IDs however do
-                qualify as v4 UUIDs.</para>
-
-                <para>In order to maintain compatibility with existing
-                installations, an application requiring a UUID should
-                decode the machine ID, and then apply the following
-                operations to turn it into a valid OSF v4 UUID. With
-                <literal>id</literal> being an unsigned character
-                array:</para>
