trafgen: Dump proto headers in *.cfg format
Added trafgen_dump.c module which dumps headers from packet
in .cfg format. Packet is dumped if -o <file>.cfg was specified,
it might be useful to specify *.pcap file as input and convert it
into .cfg file to edit proto fields in human readable format.
To make it possible several main changes were added:
1) packet id is embedded into struct packet.id, and
it is updated on each realloc_packet()
2) Added new struct proto_hdr.get_next_proto callback
to make possible apply fields of next header.
3) Added new dev_io ops for writting packets into .cfg file,
to re-use common dev_io mechsnism for packets dumping.
Before dump the default ETH_PROTO fields are applied as first header and
then next proto_hdr is identified via .get_next_proto(...) callback.
Meanwhile only eth, arp, vlan, ip4, udp, & tcp protos can be dissected
into *.cfg format.
