iodine does not seem to follow any styling guidelines (mixture of
different function prototypes, ...). So let's introduce some. This
will improve overall code quality and readability.
Additionally, warnings will improve code quality as well. Let's turn on
very pedantic warnings, and fix everything where the compiler barks
back.
Introduce the following function definition scheme:
type function_name(type name, type1 name1 ...)
{
}
This allows us to copy and paste the definition to the declaration by
selecting one single line.
Furthermore, limit line length to 80 characters.

Like other unix tools: don't print application output, if the user asks
intentionally for help.

Those arguments were introduced, but not documented.
Fixes: 619ede5d ("Add options to force IP version for client DNS traffic")

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.

Option BindIPv6Only is needed to restrict ipv6 to sending IPv6 packets
only, without it IPv6 socket can be used to send and receive packet to
and from an IPv6 address or an IPv4-mapped IPv6 address.
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.
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.
Add a struct with multiple dns file descriptors (for IPv4 and IPv6)
and pass this to required areas. Choose which descriptor to use when
sending by looking at the destination address family.
