8c5127b375 don't zero-initialise variable
For global variables, the C standard ensures that this variable will be
zeroed on startup.

4591cafd27 encoding: simplify {places,eats}_dots
Why not using constant bools?

Much simpler than complex function calls, that eventually return
constant values.

0eb3b65158 encoding: use simple int's instead of accessor functions
Why are those values exposed to the outer world? They seem not be in use
anyway.

6b438e7517 encoder: further simplifications
Get rid of unique header files for each encoder, consolidate them to
where they are actually needed: encoding.h.

This also simplifies the generation of the base64u decoder, as its
header file does not need to be generated any longer.

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.

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.

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.
