- Update the file builder generator to handle generator specific cflags and includes. The tcpdump and libpcap have localised headers and need specific headers paths to see them. There are also module specific flags and these need to be passed to the lex and yacc generators. - Add the tcpdump support.

/*

|
* We use the "receiver-makes-right" approach to byte order,
|
|
* because time is at a premium when we are writing the file.
|
|
* In other words, the pcap_file_header and pcap_pkthdr,
|
|
* records are written in host byte order.
|
|
* Note that the bytes of packet data are written out in the order in
|
|
* which they were received, so multi-byte fields in packets are not
|
|
* written in host byte order, they're written in whatever order the
|
|
* sending machine put them in.
|
|
*
|
|
* ntoh[ls] aren't sufficient because we might need to swap on a big-endian
|
|
* machine (if the file was written in little-end order).
