* fixed inconsistent processing of remaining flows during nDPId shutdown phase
* fixed multiple `detected' flow events
(instead only `detection-update' flow events can occur after a `detected' flow event)
* fixed nDPIsrvd.py invalid message buffer handling
* improved run_tests.sh so only valid pcap capture files are getting processed
(and some more cosmetics + logging)

* added another Python search path and try-catch ModuleNotFoundError again
* run_tests.sh checks for OpenBSD netcat (required for -q)

* 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

* Make use of flow id / alias / source which is required for future use cases where multiple nDPId instances (same / different machines) feed one nDPIsrvd.

* Simplified Python interface as well.
* c-captured and flow-undetected-to-pcap.py produce similiar results
* Removed overloaded nDPIsrvd.py event structures.
* flow-info.py prints (with a color-hash) additional information e.g. alias/source and midstream

* nDPIsrvd.h does flow mgmt out of the box
* dissect received JSON strings via callback
* added new JSON key/values for packet-flows (usecTimestamp/L3/L4 info)

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

* Making Compare&Fetch mandatory.
* Added some more Compare&Fetch to prevent TSAN complaining about data races.
Fixed possible but more ore less harmless data races during shutdown process.
* Shrink SIGNAL handler to a minimum. SYSV Signal handling and MT-safety is awkward.

Two reasons:
* reduce heap memory allocations
* nDPId flow info struct may be inflated in the future (more bytes to compress)

* 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())
Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* added .gitignore to prevent SCM check-ins of unwanted files
* fixed invalid include path for python examples

* This event will be triggered when nDPI detection has some new information for us (hopefully).
* Detection change is based on hashing with 32-bit murmur3 certain members of the ndpi flow struct.
