src: add fprintf API functions
Now it's possible to print directly from libnftables to a file or
other stream. The caller must explicitly print the trailing '\n'
in this call.
The error reporting of fprintf (< 0) is respected. However, we have
already print some information in case that the default (plain text)
output is used, that output is mostly intended for debugging so it
should not be a problem.
