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><function>sd_seat_get_active()</function> may be
-                used to determine which session is currently active on
-                a seat, if there is any. Returns the session
-                identifier and the user identifier of the Unix user
-                the session is belonging to. Either the session or the
-                user identifier parameter can be passed NULL, in
-                case only one of the parameters shall be queried. The
-                returned string needs to be freed with the libc
-                <citerefentry><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
-                call after use.</para>
-
-                <para><function>sd_seat_get_sessions()</function> may
-                be used to determine all sessions on the specified
-                seat. Returns two arrays, one (NULL terminated) with
-                the session identifiers of the sessions and one with
-                the user identifiers of the Unix users the sessions
-                belong to. An additional parameter may be used to
-                return the number of entries in the latter array. The
-                two arrays and the latter parameter may be passed as
-                NULL in case these values need not to be
-                determined. The arrays and the strings referenced by
-                them need to be freed with the libc
-                <citerefentry><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
-                call after use. Note that instead of an empty array
-                NULL may be returned and should be considered
-                equivalent to an empty array.</para>
-
-                <para><function>sd_seat_can_multi_session()</function>
-                may be used to determine whether a specific seat is
-                capable of multi-session, i.e. allows multiple login
-                sessions in parallel (with only one being active at a
-                time).</para>
-
-                <para><function>sd_seat_can_tty()</function> may be
-                used to determine whether a specific seat provides TTY
-                functionality, i.e. is useful as a text console.</para>
-
-                <para><function>sd_seat_can_graphical()</function> may
-                be used to determine whether a specific seat provides
-                graphics functionality, i.e. is useful as a graphics
-                display.</para>
-
-                <para>If the <literal>seat</literal> parameter of any
-                of these functions is passed as NULL the operation is
-                executed for the seat of the session of the calling
-                process, if there is any.</para>

-                <function>sd_seat_get_active()</function>
-                returns 0 or a positive integer. On success
-                <function>sd_seat_get_sessions()</function> returns
-                the number of entries in the session identifier
-                array. If the test succeeds
-                <function>sd_seat_can_multi_session</function>,
-                <function>sd_seat_can_tty</function> and
-                <function>sd_seat_can_graphical</function> return a
-                positive integer, if it fails 0. On failure, these
-                calls return a negative errno-style error code.</para>
