25b8ac3c90 Use m_dup() instead of m_copypacket() to duplicate the mbuf chain. 
This fixes a bug where if the original packet was modified downstream
of the tee node, then the copy could get modified too.

81fceb37a9 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.

d6eae9ff98 Change the prototype of the strto* routines to make the second 
parameter a char ** instead of a const char **.  This make these
kernel routines consistent with the corresponding libc userland
routines.

Which is actually 'correct' is debatable, but consistency and
following the spec was deemed more important in this case.

6f20b456fb Revamped and more useful PPP node type, supporting multi-link PPP directly. 
This is one piece of the grand unified PPP daemon concept, whereby using
netgraph nodes enables PPP data to be handled completely in kernel land,
while leaving negotiation/control to be handled by a single user land
daemon, no matter what the link type(s).

This is a safety checkin only; it compiles, but is utterly untested.
