Ralf Ramsauer 52c4940523 Warn, warn warn. 
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.

Ralf Ramsauer 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.

Erik Ekman 3ebcd29b13 Add support for using an unspecified RR type 
Add PRIVATE query type with id 65399 (private use range).
According to RFC3597 the reply data in a query with unspecified RR type must be handled
as unstructured binary data, which means it can contain raw packet data just like the NULL type.
Since the reply format is optimal it is ordered just after NULL in the priority order.

Erik Ekman a1d88c4f0a IPv6 support for client (#107) 
The iodine client now supports both IPv4 and IPv6 nameservers for
sending DNS queries to an IPv4 iodined. The nameserver will
transparently handle translation between IP protocols.

Windows port needs Vista or later to support IPv6.
