Filipe Brandenburger 681eb9cf2b man: generate configured paths in manpages
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions
like Debian which still have not adopted a /usr merge setup.

Use XML entities from man/custom-entities.ent to replace configured paths while
doing XSLT processing of the original XML files. There was precedent of some
files (such as systemd.generator.xml) which were already using this approach.

This addresses most of the (manual) fixes from this patch:
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220

The idea of using generic XML entities was presented here:
http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html

This patch solves almost all the issues, with the exception of:
- Path to /bin/mount and /bin/umount.
- Generic statements about preference of /lib over /etc.

These will be handled separately by follow up patches.

Tested:
- With default configure settings, ran "make install" to two separate
  directories and compared the output to confirm they matched exactly.
- Used a set of configure flags including $CONFFLAGS from Debian:
  http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules
  Installed the tree and confirmed the paths use /lib/systemd instead of
  /usr/lib/systemd and that no other unexpected differences exist.
- Confirmed that `make distcheck` still passes.

<title>Description</title>
<para><command>systemd-activate</command> can be used to
launch a socket activated daemon from the command line for
testing purposes. It can also be used to launch single instances
of the daemon per connection (inetd-style).
</para>
<para>The daemon to launch and its options should be specified
after options intended for <command>systemd-activate</command>.
</para>
<para>If the <option>-a</option> option is given, file descriptor
of the connection will be used as the standard input and output of
the launched process. Otherwise, standard input and output will be
inherited, and sockets will be passed through file descriptors 3
and higher. Sockets passed through <varname>$LISTEN_FDS</varname>
to <command>systemd-activate</command> will be passed through to
the daemon, in the original positions. Other sockets specified
with <option>--listen</option> will use consecutive descriptors.
