ae 545ce709f1 Rework ipfw dynamic states implementation to be lockless on fast path.
o added struct ipfw_dyn_info that keeps all needed for ipfw_chk and
  for dynamic states implementation information;
o added DYN_LOOKUP_NEEDED() macro that can be used to determine the
  need of new lookup of dynamic states;
o ipfw_dyn_rule now becomes obsolete. Currently it used to pass
  information from kernel to userland only.
o IPv4 and IPv6 states now described by different structures
  dyn_ipv4_state and dyn_ipv6_state;
o IPv6 scope zones support is added;
o ipfw(4) now depends from Concurrency Kit;
o states are linked with "entry" field using CK_SLIST. This allows
  lockless lookup and protected by mutex modifications.
o the "expired" SLIST field is used for states expiring.
o struct dyn_data is used to keep generic information for both IPv4
  and IPv6;
o struct dyn_parent is used to keep O_LIMIT_PARENT information;
o IPv4 and IPv6 states are stored in different hash tables;
o O_LIMIT_PARENT states now are kept separately from O_LIMIT and
  O_KEEP_STATE states;
o per-cpu dyn_hp pointers are used to implement hazard pointers and they
  prevent freeing states that are locklessly used by lookup threads;
o mutexes to protect modification of lists in hash tables now kept in
  separate arrays. 65535 limit to maximum number of hash buckets now
  removed.
o Separate lookup and install functions added for IPv4 and IPv6 states
  and for parent states.
o By default now is used Jenkinks hash function.
