    sys/netgraph/bluetooth/socket ng_btsocket.c 
  Log:
  Move ng_socket and ng_btsocket initialization to SI_SUB_PROTO_DOMAIN as they
  call net_add_domain(). Calling this function too early (or late) breaks
  assertations about the global domains list.
  Actually it should be forbidden to call net_add_domain() outside of
  SI_SUB_PROTO_DOMAIN completely as there are many places where we traverse
  the domains list unprotected, but for now we allow late calls (mostly to
  support netgraph). In order to really fix this we have to lock the domains
  list in all places or find another way to ensure that we can safely walk the
  list while another thread might be adding a new domain.
