46f68501d5 Added daemon event: DAEMON_EVENT_STATUS (periodically send's daemon statistics.)
* Improved distributor timeout handling (per-thread).
 * flow-info.py / flow-dash.py: Distinguish between flow risk severities.
 * nDPId: Skip tag switch datalink packet dissection / processing.
 * nDPId: Fixed incorrect value for current active flows.
 * Improved JSON schema's.

6fd6dff14d Added additional (minimalistic) detection information to flow updates.
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

9e07a57566 Major nDPId extension. Sorry for the huge commit.
- 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

f713ec702b Added nDPId semantic validation test.
* 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)
