* 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

* more structs are now "compressable"
* fixed missing DAEMON_RECONNECT event
* improved memory profiler

How? After the detection finished, internal ndpi structs can be free'd as they are not needed anymore.
* Set the amount of max. packets to process via subopt.

* 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.

* 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.
