- 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

* After the first packet was processed, "flow_last_seen" was still 0.
This behaviour is invalid as the first packet may contain l4 payload data e.g. for UDP
and it also breaks nDPId json consistency "flow_first_seen" > 0, but "flow_last_seen" == 0.
* JSON schema: set minimum timestamp value for Epoch timestamps to 24710 for flow_*_seen and
1 for pcap packet ts. Those values are dependant on some manipulated pcap's in libnDPI/tests/pcap.
