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

* 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.

* nDPIsrvd: Collector/Distributor logging improved
* nDPIsrvd: Command line option for max remote descriptors
* nDPId: Stop spamming nDPIsrvd Collector with the same events over and over again
* nDPId: Refactored some variable names and events

* fixed GitLab pipeline
* nDPId: added static assert (just for a test)
* nDPId: memory profiling for total bytes compressed
* nDPId-test: enable zLib compression if configured with ENABLE_ZLIB

- nDPId: fixed invalid IP4/IP6 tuple compare
- nDPIsrvd: fixed caching issue (finally)
- added tiny c example (can be used to check flow manager sanity)
- c-captured: use flow_last_seen timestamp from `struct nDPIsrvd_flow`
- README.md update: added example JSON sequence
- nDPId: added new flow event `update` necessary for correct
timeout handling (and other future use-cases)
- nDPIsrvd.h and nDPIsrvd.py: switched to an instance
(consists of an alias/source tuple) based flow manager
- every flow related event **must** now serialize `alias`, `source`,
`flow_id`, `flow_last_seen` and `flow_idle_time` to make the timeout
handling and verification process work correctly
- nDPIsrvd.h: ability to profile any dynamic memory (de-)allocation
- nDPIsrvd.py: removed PcapPacket class (unused)
- py-flow-dashboard and py-flow-multiprocess: fixed race condition
- py-flow-info: print statusbar with probably useful information
- nDPId/nDPIsrvd.h: switched from packet-flow only timestamps (`pkt_*sec`)
to a generic flow event timestamp `ts_msec`
- nDPId-test: added additional checks
- nDPId: increased ICMP flow timeout
- nDPId: using event based i/o if capturing packets from a device
- nDPIsrvd: fixed memory leak on shutdown if remote descriptors
were still connected

* nDPId-test: disable #include <syslog.h> if NO_MAIN macro defined
* nDPId-test: mock syslog flags and functions
* gitlab-ci: force -Werror

* c-collectd gives the user control over collectd-exec instance name
* added missing collectd type `flow_l4_icmp_count`

* improved Makefile.old install targets
* splitted nDPIsrvd_parse into nDPIsrvd_parse_line and nDPIsrvd_parse_all for the sake of readability
* minor Python script improvments (check for nDPIsrvd.py on multiple locations, may be superseeded by setuptools in the future)
* some paths needs to be absolute (chdir() during daemonize) and therefor additional checks introduced
* test run script checks and fails if certain files are are missing (PCAP file <=> result output file)
* removed not very useful "internal format error" JSON serialization if a BUG for same exists
* fixed invalid l4 type statistics counters for nDPIsrvd-collectd
Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* fixed invalid flow event schema type
* added run_tests.sh to generate/diff JSON dumps
* renamed lot's of vars/fns in nDPId.c/nDPIsrvd.c, so nDPId-test.c can include "*.c"
* improved CMake dependency checks

* Fixed ARM32 xcompile warnings; Other GCC versions, other uint64_t's..
* Replaced ridiculous nDPIsrvd_JSON_BYTES with NETWORK_BUFFER_LENGTH_DIGITS.

Switching back to blocking mode works as a quick fix but is not sufficient.
See comments.
* nDPId prints more accurate error messages if command line argument validation failed

* Added pcap diff script
* Added \n to JSON string end (useful for debugging and readability)
* Use first host/server name character for hash calculation as well
* Removed error'ing EPOLLHUP handling in nDPIsrvd (connection closing will be detected via read())
