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
