IPv6 support for DNS traffic in server

Server will by default listen on both IPv4 and IPv6.
No way to only listen on one protocol right now.
Use -L to only listen on a specific v6 address.
IP address to use for raw mode is still IPv4 only.
Use -n on server to make raw mode work from IPv6 clients,
then they will get an IPv4 address from the server for raw mode.
Tunnel data is still IPv4.

Support utun devices on Mac OS X.
...
As of 10.6, OS X has native tunnel devices. They are implemented as
sockets rather than character devices, but otherwise they appear to
behave the same as Free/OpenBSD tunnels.
'-d utunX' will tell iodine to use a utun device. For backward
compatibility, we'll continue to default to the old tuntap devices for
now.
This is a port of Peter Sagerson <psagers.github@ignorare.net>'s openvpn
commit 43e5016a.

osflags: use pkg-config for systemd support
...
Recent versions of systemd don't ship with libsystemd-daemon.so anymore,
but instead use libsystemd.so for everything. This is obviously
problematic for using the same LDFLAGS on old systemd and new systemd.
So, they also ship compatability pkgconfig files, which use the old
names but return the new library. So, the most portable way to support
both old and new systemd is to use pkgconfig. It's not a problem either,
since systems that use systemd are bound to also have pkgconfig
installed.
