Add two new generic control messages, NGM_ASCII2BINARY and
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.

Revert parts of 1.51 and add a missing \& after "i.e." that is not the
end of a sentence. Ruslan notes that:

* The part about hexadecimal representation was intentional -- node ID
is parsed as the ng_parse_hint32_type, and is represented
(input/output) as a hexadecimal number

* "This value" was more correct, as the alternative name is
"[<value>]:" where <value> is hexadecimal value of the node ID.

* "ID based name" (which is "[<hexid>]:") was correct, and what's now is
incorrect -- node ID (number) cannot be equivalent to a name.
