appletalk: move the protocol out of tree

Browse Source 
AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009,
according to Wikipedia. We recently got a burst of AI generated
fixes to this protocol which nobody is reviewing.

Let AppleTalk follow AX.25 and hamradio out of the Linux tree.
We we will maintain the code at: github.com/linux-netdev/mod-orphan
for anyone interested in playing with it.

Retain the uAPI for now. No strong reason, simply because I suspect
keeping it will be less controversial.

4. Appletalk
------------
The /proc/sys/net/appletalk directory holds the Appletalk configuration data
when Appletalk is loaded. The configurable parameters are:
aarp-expiry-time
----------------
The amount of time we keep an ARP entry before expiring it. Used to age out
old hosts.
aarp-resolve-time
-----------------
The amount of time we will spend trying to resolve an Appletalk address.
aarp-retransmit-limit
---------------------
The number of times we will retransmit a query before giving up.
aarp-tick-time
--------------
Controls the rate at which expires are checked.
The directory /proc/net/appletalk holds the list of active Appletalk sockets
on a machine.
The fields indicate the DDP type, the local address (in network:node format)
the remote address, the size of the transmit pending queue, the size of the
received queue (bytes waiting for applications to read) the state and the uid
owning the socket.
/proc/net/atalk_iface lists all the interfaces configured for appletalk.It
shows the name of the interface, its Appletalk address, the network range on
that address (or network number for phase 1 networks), and the status of the
interface.
/proc/net/atalk_route lists each known network route. It lists the target
(network) that the route leads to, the router (may be directly connected), the
route flags, and the device the route is using.

AppleTalk is the protocol that Apple computers can use to communicate
on a network. If your Linux box is connected to such a network and you
wish to connect to it, say Y. You will need to use the netatalk package
so that your Linux box can act as a print and file server for Macs as
well as access AppleTalk printers. Check out
<http://www.zettabyte.net/netatalk/> on the WWW for details.
EtherTalk is the name used for AppleTalk over Ethernet and the
cheaper and slower LocalTalk is AppleTalk over a proprietary Apple
network using serial links. EtherTalk and LocalTalk are fully
supported by Linux.
General information about how to connect Linux, Windows machines and
Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>. The
NET3-4-HOWTO, available from
<http://www.tldp.org/docs.html#howto>, contains valuable
information as well.
To compile this driver as a module, choose M here: the module will be
called appletalk. You almost certainly want to compile it as a
module so you can restart your AppleTalk stack without rebooting
your machine. I hear that the GNU boycott of Apple is over, so
even politically correct people are allowed to say Y here.
