Refactored client distributor C API.

 * Still not perfect, but the code before was not even able to deal with JSON arrays.
   Use common "speaking" function names for all functions in nDPIsrvd.h
 * Provide a more or less generic and easy extendable JSON walk function.
 * Modified C examples to align with the changed C API.
 * c-collectd: Reduced lot's of code duplication by providing mapping tables.
 * nDPId: IAT array requires one slot less (first packet has always an IAT of 0).
