* 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

* py-flow-dashboard: Added color mapping for PieCharts/Graph that make more sense
* nDPId: Renamed `flow_type' to a more precisely `flow_state'
* nDPId: Changed the default setting to process only as much packets as libnDPI does

This will only affect flows with the state `FT_FINISHED' (detection done).
* nDPIsrvd.py: force use of JSON schema Draft 7 validator
* flow-dash.py: gather/use total processed layer4 payload size
* flow-info.py: added additional event filter
* flow-info.py: prettified flow events printing whose detection is in progress
* py-semantic-validation.py: added validation checks for FT_FINISHED
* updated flow event JSON schema

* TCP timeout after FIN/RST: switched back to the value from a35fc1d5ea
* py-flow-info: reset 'guessed' flag after detection/detection-update received

- 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

* added another Python search path and try-catch ModuleNotFoundError again
* run_tests.sh checks for OpenBSD netcat (required for -q)
Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* 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

* 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
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
