* incorporated upstream API changes related to detection protocol bitmasks
* added missing flow detection categories

* added new CMake option `ENABLE_MEMORY_STATUS` to restore the old behavior
(and increase performance)
* splitted `ENABLE_MEMORY_PROFILING` into `ENABLE_MEMORY_STATUS` and `ENABLE_MEMORY_PROFILING`

* 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.

* try to use same wording wherever possible e.g.
renamed workflow->total_l4_data_len to workflow->total_l4_payload_len

* nDPIsrvd.h: Provide nDPId thread storage.
* nDPIsrvd.py: Fixed instance cleanup bug.
* nDPIsrvd.h: Support for instance/thread user data and cleanup callback.
* nDPIsrvd.h: Most recent flow time stored in thread ht instead of instance ht.
* nDPId: Moved flow logger out the memory profilier into SIGUSR1 signal handling.
* nDPId: Added signal fd to be usable within epoll's event handling (live-capture only!)
* nDPId: Added information about ZLib compressions to daemon status/shutdown events.

- 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
