packet capture: don't reuse socket for multiple receive functions
TPACKET_V[23]: continue even if mlock() fails
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
