Detected by activating stronger warnings. If include is missing,
prototypes might diverge.

1c86bf347f iodine/iodined: do not print usage if no superuser 
There is no value in printing the usage in this case, as the usage
doesn't give the user any hint on how to solve this issue.

Furthermore, replace the Windows implementation with an empty inline
function, which will result in no code.

Build position-indepent executables, required for Android L (5.0+)
They also work with kitkat.

Add new maketarget "cross-android-old" that builds without PIE
for older versions.

Include both new and old versions in latest-android.zip. Add arm64.

Hopefully solves github PR #14.

7a117bd71e 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.

and pass this to required areas. Choose which descriptor to use when
sending by looking at the destination address family.

33abc0ca26 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.
