complete error checking on every sys/lib call

Solaris compile issues

only works on ethernet interfaces

icmd: c: don't remove closed connections

icmd: n: don't display new connections

icmd: s: enable/disable sorting

icmd: p: pause display

clopt: no sorting

clopt: closed connections remove timeout

clopt: units (B/s KB/s)

clopt: display refresh interval

Be able to pick up connections that we didn't see the SYN for

dont call exit() from within objects, throw an exception or something

clean close down... stop curses nicely

put stuff in main in an app class

display interval too long on freebsd

get rid of my List.h, use STL

make UI scrollable list, using curses pad

make UI occupy full window size horizontally

make debug log allow format string like printf

make configure look for pcap/pcap.h and if found, add -I/usr/include/pcap or
something like that to compilation. might fix redhat packaging issue

duplicate excess -I in compilation

etherreal extension?
