5d5ea68a69 Use 'type_name' structure field instead of 'typename', which is 
a C++ reserved work.

Add a ng_copy_meta() function.

119898c763 A netgraph node that implements Microsoft Point-to-Point compression 
(MPPC) and Microsoft Point-to-Point encryption (MPPE) protocols.

Note: the MPPC part is disabled as it requires proprietary files.

008dd6112b 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

a5782dd663 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" 
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

f95f4dac4c 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.

b600a98c28 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.
