Erik Ekman f5a82afe29 Initialize get_resolvconf_addr variable rv to NULL
Getting warning compiling for Android:

./util.c:35:6: warning: variable 'rv' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        if (sscanf(buf, "%15s", addr) == 1)
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./util.c:79:9: note: uninitialized use occurs here
        return rv;

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 ccc49f16f7 util: add missing #includes
Detected by activating stronger warnings. If include is missing,
prototypes might diverge.
