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_journal_seek_head()</function>
- seeks to the beginning of the journal, i.e. the oldest
- available entry.</para>
-
- <para>Similar,
- <function>sd_journal_seek_tail()</function> may be
- used to seek to the end of the journal, i.e. the most
- recent available entry.</para>
-
- <para><function>sd_journal_seek_monotonic_usec()</function>
- seeks to the entry with the specified monotonic
- timestamp, i.e. CLOCK_MONOOTONIC. Since monotonic time
- restarts on every reboot a boot ID needs to be
- specified as well.</para>
-
- <para><function>sd_journal_seek_realtime_usec()</function>
- seeks to the entry with the specified realtime
- (wallclock) timestamp, i.e. CLOCK_REALTIME. Note that
- the realtime clock is not necessarily monotonic. If a
- realtime timestamp is ambiguous it is not defined
- which position is sought to.</para>
-
- <para><function>sd_journal_seek_cursor()</function>
- seeks to the entry located at the specified cursor
- string. For details on cursors see
- <citerefentry><refentrytitle>sd_journal_get_cursor</refentrytitle><manvolnum>3</manvolnum></citerefentry>. If
- no entry matching the specified cursor is found the
- call will seek to the next closest entry (in terms of
- time) instead. To verify whether the newly selected
- entry actually matches the cursor use
- <citerefentry><refentrytitle>sd_journal_test_cursor</refentrytitle><manvolnum>3</manvolnum></citerefentry>.</para>
-
- <para>Note that these calls do not actually make any
- entry the new current entry, this needs to be done in
- a separate step with a subsequent
- <citerefentry><refentrytitle>sd_journal_next</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- invocation (or a similar call). Only then entry data
- may be retrieved via
- <citerefentry><refentrytitle>sd_journal_get_data</refentrytitle><manvolnum>3</manvolnum></citerefentry>. If
- no entry exists that matches exactly the specified
- seek address the next closest is sought to. If
- <citerefentry><refentrytitle>sd_journal_next</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- is used the closest following entry will be sought to,
- if
- <citerefentry><refentrytitle>sd_journal_previous</refentrytitle><manvolnum>3</manvolnum></citerefentry>
- is used the closest preceding entry is sought
- to.</para>
