48b5fd636e Modify the DoParseCommand() to work on (const char *) instead of just
(char *). This is a slightly simplified version of the patch in the PR. It
fixes compilitation issues with -O3.

b9124a7354 Add line edit and history support to ngctl(8) via editline(3).
Details:
- The main thread runs editline(3) functions, that can block.
- A separate thread is launched to monitor netgraph sockets.
- The access to the descriptors is protected by a mutex. At
  runtime the monitoring thread owns the mutex. When the main
  thread reads a command from el_gets() it asks the monitoring
  thread to release a mutex and sleep until the main thread
  processes the command.

This makes ngctl(8) depend on libedit, and libpthread. Thus, the
new functionality isn't compiled in if release is being built
with -DRELEASE_CRUNCH.

to deal with a big number of nodes.

bbd6d60a85 Add a GraphViz-exporting ngctl(8) "dot" command. You can now create
very useful .dot files of your netgraph(4) to quickly visualize the
nodes, hooks and edges.  An example of this can be found here:
	http://people.freebsd.org/~green/sample-netgraph-dot.ps
If anyone would like to refine the output further, please do so.

Somebody submitted this long time ago, and it has been sitting in my

b08b2814a1 No need to try loading ng_socket.ko, as NgMkSockNode() does that

f8307e1233 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.

0d6985e2c1 If we get an EPROTONOSUPP error when trying to create the netgraph socket
node, it's most likely because the "ng_socket.ko" KLD is not loaded yet.
So make an attempt to load it before giving up.
