Variable cleanup following break-out of kern_mac.c into sys/security/mac:

Unstaticize mac_late.
  Remove ea_warn_once, now in mac_vfs.c.
  Unstaticisize mac_policy_list, mac_static_policy_list, use
    struct mac_policy_list_head instead of LIST_HEAD() directly.
  Unstaticize and un-inline MAC policy locking functions so they can
    be referenced from mac_*.c.
