Subject: Bump up packet and byte counters to 64-bit unsigned ints.  As a
 consequence, ipfw's list command now adjusts its output at runtime based on
 the largest packet/byte counter values.

NOTE:
  o The ipfw struct has changed requiring a recompile of both kernel
    and userland ipfw utility.

  o This probably should not be brought into 2.2.
