Read and parse configuration files. Fixes#41.
* supports nDPId / nDPIsrvd via command line parameter `-f`
* nDPId: read general/tuning and libnDPI settings
* support for settings risk domains libnDPI option via config file or via `-R` (Fixes#45, thanks to @UnveilTech)
* added some documentation in the config file
* adjusted Systemd and Debian packaging to make use of config files

* added new CMake option `ENABLE_MEMORY_STATUS` to restore the old behavior
(and increase performance)
* splitted `ENABLE_MEMORY_PROFILING` into `ENABLE_MEMORY_STATUS` and `ENABLE_MEMORY_PROFILING`

* a "detection-update" event was thrown even if nothing changed
* in some cases "not-detected" events were spammed if detection not completed
* tell `libnDPI` how many packets per flow we want to dissect
* `nDPId-test` validates total active flows in the right way

* Fixed risk hash value calculation, which was only done lower 32 bits.
* Reduced default reader threads count to two if cross compiling.

* Add MacOS to Github CI builds.
* Fixed libnDPI-4.8 CI build.
* Fixed missing include for `struct sockaddr*`.
* Reworked IPv4 address and netmask retrieval.

* Finalize Event I/O abstraction layer.
* Fix possible fd leakage, Gitlab-CI build and error logging.
* Fixed possible uninitialized signalfd variable.
* Fixed possible memory leak.
* Fixed some SonarCloud complaints.
* Fixed nDPId-test nDPIsrvd-arpa-mockup stuck indefinitely.
* Add nDPId / nDPIsrvd command line option to use poll() on Linux instead of the default epoll().

* py-semantic-validation: Decode base64 raw packet data as well
* nDPIsrvd.py: Added PACKETS_PLEN_MAX
* nDPIsrvd.py: Improved JSON parse error/exception handling

* 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.

* nDPId/nDPIsrvd/c-examples: Parameter parsing needs to be improved
if `strdup()` in combination with static strings is used.
* Other non-critical fixes.

* The issue can result in an error message like:
`Base64 encoding failed with: Buffer too small.`
and also in too big JSON strings generated by nDPId
which nDPIsrvd does not like as it's length is
greater than `NETWORK_BUFFER_MAX_SIZE`.
* nDPId will now obey `NETWORK_BUFFER_MAX_SIZE` while
trying to base64 encode raw packet data.

* 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).
