Gleb Smirnoff 95d1f36f82 Optimize parallel processing of ipfw(4) rulesets eliminating the locking 
of the radix lookup tables. Since several rnh_lookup() can run in
parallel on the same table, we can piggyback on the shared locking
provided by ipfw(4).
  However, the single entry cache in the ip_fw_table can't be used lockless,
so it is removed. This pessimizes two cases: processing of bursts of similar
packets and matching one packet against the same table several times during
one ipfw_chk() lookup. To optimize the processing of similar packet bursts
administrator should use stateful firewall. To optimize the second problem
a solution will be provided soon.

Details:
  o Since we piggyback on the ipfw(4) locking, and the latter is per-chain,
    the tables are moved from the global declaration to the
    struct ip_fw_chain.
  o The struct ip_fw_table is shrunk to one entry and thus vanished.
  o All table manipulating functions are extended to accept the struct
    ip_fw_chain * argument.
  o All table modifing functions use IPFW_WLOCK_ASSERT().
