Erich Eckner be0735d7c7 documentation: make it clear, what incompleteness -b has 
AXFR does not pass through iodine (sounds reasonable), so we should
recommend in the README.md to keep the original dns server in front if
zone transfers are required.

gregor herrmann 024481c94b Fix cross compilation 
src/osflags hard codes the build architecture pkg-config. After making it
substitutable and substituting it from the build environment, iodine cross
builds successfully.

Ralf Ramsauer 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.

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.

Furthermore, replace the Windows implementation with an empty inline
