[Click] Logging packet data to disk

[John Bicket]

We have had this same issue, and we generally do one of two things:
1. someone (Doug or Dan?) wrote elements/grid/packetlogger.cc and
elements/grid/packetlogger2.cc which stores packets which you can
read out of the handler "log".
2. Use something like "ToHost(fakedump)" in your config and send
it all the packets you want recorded; you can run
"tcpdump -i fakedump -w foo.dump"
and it will grab the packets you hand to tohost and put them in a file.
