ec6a1ac308 Fix IPv4 address in replies to A or NS queries (github issue #38) 
The destination field in struct query was changed from in_addr_t to
struct sockaddr_storage, wihtout updating the functions sending it
in src/dns.c.

Only add extra A answer for NS queries if destination refers to an
IPv4 address, and fail if trying to encode a reply to an A query
if destination is not IPv4.

This means NS requests received over IPv6 will not contain an address
and A requests will be ignored, unless the -n option is used, or the
www subdomain is requested which sets a fixed address (127.0.0.1).

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.

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.
