Stable release

Changes

• Add signal handlers to gracefully shut down the SIP, P2P and HTTP daemons
• Move SIP daemon into its own thread
• Integrate the Zyre library for proximity-based Peer to Peer support with tests
• Integrate the OpenDHT library for a
  Kademlia like distributed key-value storage with tests. We will store the
  public IP addresses of the nodes in the DHT so peers can find each other and share collected data
• Zyre and OpenDHT are optional and detected at build time
• Add destination_ip to bad_actor data structure
• Add JSON logging to log bad actor events to a json file via -j flag and SENTRYPEER_JSON_LOG environment variable,
  plus custom log file location via -l flag and SENTRYPEER_JSON_LOG_FILE environment variable
• Add --disable-opendht/zyre flags to disable OpenDHT and Zyre build requirements. This allows a user to run
  SentryPeer as a full standalone node done at build time

Tests

• Clean up all valgrind warnings
• Use the new http_daemon_stop() which calls MHD_stop_daemon() to clear up memory leaks, sockets etc. in tests
• Add tests for the sip_daemon_XXXX() functions
• Add tests for the peer_to_peer_lan_XXXX() functions
• Add tests for the peer_to_peer_dht_XXXX() functions
• Switch to cmocka XML output format to show time taken for each test
• Update tests for new JSON log format and new destination_ip field in bad_actor data structure
