Backout my previous commit, it appearantly doesn't work for asynchronous
messages.

Add -ledit to ngctl.

Somebody submitted this long time ago, and it has been sitting in my
tree for months because I thought archie would pick it up.

Fix bug in "read" command.

Experiemntal ascii based device configuration mechanism.

This may or may not survive, decision will be made well before 5.0-R

When the 'msg' command is used from the command line, check for a
synchronous reply, and display it (if any) before exiting.

No need to try loading ng_socket.ko, as NgMkSockNode() does that
for us now if necessary.

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.

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.

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.
