Updates to the ng_iface(8) netgraph node type:
...
- Make iface nodes removable on shutdown since FreeBSD now supports
removable interfaces
- Simplify supporting new protocols using family_enqueue(); add a
few new ones including IPv6
- Add support for configurable interface mode using new
NGM_IFACE_POINT2POINT and NGM_IFACE_BROADCAST control messages
- Remove NGM_IFACE_GET_IFADDRS control message; it just duplicates
the functionality of SIOCGIFCONF

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.

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.
