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.
