NGM_BINARY2ASCII, which convert control messages to ASCII and back. This allows control messages to be sent and received in ASCII form using ngctl(8), which makes ngctl a lot more useful. This also allows all the type-specific debugging code in libnetgraph to go away -- instead, we just ask the node itself to do the ASCII translation for us. Currently, all generic control messages are supported, as well as messages associated with the following node types: async, cisco, ksocket, and ppp. See /usr/share/examples/netgraph/ngctl for an example of using this. Also give ngctl(8) the ability to print out incoming data and control messages at any time. Eventually nghook(8) may be subsumed. Several other misc. bug fixes. Reviewed by: julian
