c0b7bdacbc Reworked nDPIsrvd.h C-API.
* 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.

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

3a76035570 bump libnDPI to 6b7e5fa8d251f11c1bae16ea892a43a92b098480
* fixed linking issue by using CMake to check if explicit link against libm required
 * make nDPIsrvd collectd exit if parent pid changed, meaning that collectd died somehow
 * nDPId-test restores SIGPIPE to the default handler (termination), so abnormal connection drop's do now have consequences

0a7ad7a76a nDPId-test: added JSON distribution + JSON parsing (Multithreaded design re-using most of nDPId/nDPIsrvd core)
* improved Makefile.old install targets
 * splitted nDPIsrvd_parse into nDPIsrvd_parse_line and nDPIsrvd_parse_all for the sake of readability
 * minor Python script improvments (check for nDPIsrvd.py on multiple locations, may be superseeded by setuptools in the future)
 * some paths needs to be absolute (chdir() during daemonize) and therefor additional checks introduced
 * test run script checks and fails if certain files are are missing (PCAP file <=> result output file)
 * removed not very useful "internal format error" JSON serialization if a BUG for same exists
 * fixed invalid l4 type statistics counters for nDPIsrvd-collectd
