appletalk: move the protocol out of tree

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.

-	tristate "Appletalk protocol support"
-	select LLC
-	help
-	  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.

- *	This doesn't fit cleanly with the IP arp. Potentially we can use

- *
- *	FIXME:
- *		We ought to handle the retransmits with a single list and a

- *		Rob Newberry	-	Added proxy AARP and AARP proc fs,
