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.

Erik Ekman 9a45c4aa66 Change license wording to follow ISC license exactly

Erik Ekman b715be5cf3 Fix authentication bypass bug 
The client could bypass the password check by continuing after getting error
from the server and guessing the network parameters. The server would still
accept the rest of the setup and also network traffic.

Add checks for normal and raw mode that user has authenticated before allowing
any other communication.

Problem found by Oscar Reparaz.
