Log:
  MFC r196501:
  
    When registering a protocol to an existing protocol domain via
    pf_proto_register(), iterate over all existing vnets to call protosw_init()
    and thus the appropriate .pr_init() handler in the context of each vnet.
    NB in the future we probably want to separate pr_init() handlers into
    two, i.e. per-vnet and global, functions.
  
    This change has no impact on nooptions VIMAGE builds.
