15b9bcb121 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.

1edd13e295 New netgraph node type, ng_bpf(8). This node type allows you to 
apply bpf(4) filters to data travelling through a netgraph network.

2bb264d4df Add a new function ng_findhook() for finding a node's hook; 
if the node type provides a more efficient implementation than
the normal linear scan, use it.

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.
