Fixed segmentation faults when trace_destroy is called on a trace that wasn't successfully created
libdl is now checked for and only linked against if available (BSD's don't have a libdl)
Fixed the libpacketdump .so's to use libtrace's generic protocol headers as well as trace_ether_ntoa
Added missing check for strlcpy
Added a couple of #defines to various tools that needed them under FreeBSD
Removed some needless #includes from the libpacketdump .so's
