This patch adds a cpp definition HAVE_SYSV_COMPAT that is used to
isolate code dealing with /etc/init.d and /etc/rcN.d for systems where
it does not make sense (one that does not use sysv or one that is fully
systemd native).
The patch tries to be as little intrusive as possible, however in
order to minimize the number of #ifdef'ed regions I've reordered some
code in path-lookup.c:lookup_paths_init() where all code dealing with
sysv is now isolated under running_as == MANAGER_SYSTEM as well.
Moreover, In struct Service, some fields were rearranged to reduce
the number of ifdefs.
Lennart's suggestions were fixed and squashed with the original patch,
that was sent by Gustavo Sverzut Barbieri (barbieri@profusion.mobi).
Arch does not use proper SysV runlevels. Instead /etc/rc.conf contains
an array of daemons to load in a multi-user runlevel, and some
dependencies between them.
This patch enables this behaviour in SystemD (only when compiled with
Arch support), which allows SystemD to be a drop in replacement on Arch
(modulo some minor bugs).
v2: simplified after suggestion from Lennart
This patch introduces socket_ipv6_is_supported() call that checks for
IPv6 availability. Code then check for it before using specific calls.
In order to be less intrusive, this patch avoids IPv6 entries being
parsed at all, this way we don't get such entries in the system and
all other code paths are automatically ignored. However an extra check
is done at socket_address_listen() to make sure of that.
As the number of Netlink messages is not know upfront anymore,
loopback-setup.c was refactored to dynamically calculate the sequence
number and count.
Lennart's suggestions were fixed and squashed with the original patch,

This patch is a bit bigger than expected since Gentoo being
non-standard in some places.
1. it is installing binaries at /usr/bin instead of /bin.
2. it is using CamelCase names for consolefonts.
3. /etc/rc.conf:unicode=(yes|no) just forbids loadkeys and setfont
"-u" options, but do not disable the actual kernel default_utf8
from vt module.
