Introduces xtables match/target registration

- moves lib_dir to xtables.c
- introduces struct pfinfo which has protocol family dependent infomations.
- unifies load_ip[6]tables_ko() and moves them as load_xtables_ko()
- introduces xt_{match,match_rule,target,tryload} and replaces
  ip[6]t_* with them
- unifies following functions and move them to xtables.c
        - find_{match,find_target}
        - compatible_revision, compatible_{match,target}_revision
- introduces xtables_register_{match,target} and make
  register_{match,target}[6] call them. xtables_register_* register ONLY
  matches/targets matched protocol family

Some concepts:
- source compatibility for libip[6]t_xxx.c with warning on compilation
  not binary compatibility.
- binary compatibility between 2.4/2.6 kernel and iptables/ip6tables,
  of cause.
- xtables is enough to support only one address family at runtime.
  Then xtables keeps infomations of only the focused address famiy
  in struct afinfo.
