man: add systemd-sysv-generator(8)

In principle SysV stuff is only for compatibility, but we are stuck
with it for the forseeable future, so documentation might as well
be provided.

+
+    <para><filename>systemd-sysv-generator</filename> is a generator
+    that creates wrapper .service units for
+    <ulink url="https://savannah.nongnu.org/projects/sysvinit">SysV init</ulink>
+    scripts in <filename>/etc/init.d/*</filename> at boot and when
+    configuration of the system manager is reloaded. This will allow
+    <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    to support them similarly to native units.</para>
+
+    <para><ulink url="http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html">LSB headers</ulink>
+    in SysV init scripts are interpreted, and the ordering specified
+    in the header is turned into dependencies between the generated
+    unit and other units. LSB facilities
+    <literal>$remote_fs</literal>, <literal>$network</literal>,
+    <literal>$named</literal>, <literal>$portmap</literal>,
+    <literal>$time</literal> are supported and will be turned into
+    dependencies on specific native systemd targets.  See
+    <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+    for more details.</para>
+
+    <para>SysV runlevels have corresponding systemd targets
+    (<filename>runlevel<replaceable>X</replaceable>.target</filename>).
+    Wrapper unit that is generated will be wanted by those targets
+    which correspond to runlevels for which the script is
+    enabled.</para>
+
+    <para><command>systemd</command> does not supports SysV scripts as
+    part of early boot, so all wrapper units are ordered after
