Changes:

• Makefile: protect mandatory compile flags
• packet capture: don't reuse socket for multiple receive functions
• TPACKET_V[23]: continue even if mlock() fails

Changes:

• ipmon: fix division by zero
• fix: detstats(), ifstats(): handle packets with incorrect header checksum
• fix: positionptr(): properly allocate newly created interfaces
• fix: detstats(): properly account non-IP packets
• fix: properly init curses (fixes view on some utf-8 terminals)
• fix: cidr_split_address(): fix buffer overflow
• ipmon: printentry(): fix printing of huge values
• build: use correct libraries (wide version of -lpanel)
• fix unsafe handling of printf() args (RedHat Bugzilla: 1842690)
• fix the CPU hog if the interface gets removed (RedHat Bugzilla: 1572750)
• introduce packet capturing abstraction: add recvmmsg(), TPACKET_V2 and TPACKET_V3 mmap()ed capturing modules: this allow us to capture in multigigabit speeds
• add partial support for IPoIB interfaces (full support cannot be done because the kernel interface doesn't give us source address) (RedHat Bugzilla: 1140211)
• merge rvnamed-ng into iptraf-ng
• allow scrolling with Home, End, PageUp and PageDown keys
• show dropped packet count
• pktsize: print in and out counters
• ifstats: show total packet rate and packet drop across all interfaces
• ipmon: show OSPF protocol version
• hostmon, ipmon: update screen only when needed (vastly reduces CPU usage and also reduces packet drops)
• update source code to compile cleanly on modern gcc
• numerous code refactoring/cleaning up all over the source tree
