* nDPId-test: Increased the max-packets-per-flow-to-send from 3 to 5.
This is quite useful for TCP as the first 3 packets are usually part of the three-way-handshake.

* 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).

* The goal was to provide a separate event for extracted feature that are not required
and only useful for a few (e.g. someone who wants do ML).
* Increased network buffer size to 32kB (8192 * 4).
* Switched timestamp precision from ms to us for *ALL* timestamps.

* export env vars AR / CMAKE_C_COMPILER_AR and RANLIB / CMAKE_C_COMPILER_RANLIB while building libnDPI
* nDPId check API version during startup (macro vs. function call) and print a warning if they are different
