Message:

Changed rt types so that every pcap dlt has a matching rt type
Added functions for conversion between rt type and pcap dlt
format_rt now uses trace_set_err appropriately if rt_connect fails
format_pcap will check if a trace is dead before trying to look at

format data

Dead traces now have their format_data set to NULL
packet->type is now 32 bits, not 8
