    ip: improve ttosubnet()
    
    Merge initsubnet()'s body.
    
    - should pass in ip_info instead of int af
    - should drop 0-length hack
    - should change 'clash' to an enum
    - since this parses addr/mask:port (stomping on the addresses
      nonexistent port) should it be split into ttosubnet() and
      ttoselector()?
