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>

- <title>Description</title>
-
- <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>
- </refsect1>

- <title>Return Value</title>
-
- <para> On success
- <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>
