  Log:
  Declare the "packet_info" structure "pi" in "packet.h", rather than in a
  bunch of source files.
  
  Replace the "payload" field of a "packet_info" structure with "len" and
  "captured_len" fields, which contain the total packet length and total
  captured packet length (including all headers) at the current protocol
  layer (i.e., if a given layer has a length field, and that length field
  says its shorter than the length we got from the capture, reduce the
  "pi.len" and "pi.captured_len" values appropriately).  Those fields can
  be used in the future if we add checks to make sure a field we're
  extracting from a packet doesn't go past the end of the packet, or past
  the captured part of the packet.
  
  Get rid of the additional payload argument to some dissection functions;
  use "pi.captured_len - offset" instead.
  
  Have the END_OF_FRAME macro use "pi.captured_len" rather than
  "fd->cap_len", so that "dissect the rest of the frame" becomes "dissect
  the rest of the packet", and doesn't dissect end-of-frame padding such
  as padding added to make an Ethernet frame 60 or more octets long.  (We
  might want to rename it END_OF_PACKET; if we ever want to label the
  end-of-frame padding for the benefit of people curious what that extra
  gunk is, we could have a separate END_OF_FRAME macro that uses
  "fd->cap_len".)
