[NET]: move config options out to individual protocols

Move the protocol specific config options out to the specific protocols.
With this change net/Kconfig now starts to become readable and serve as a
good basis for further re-structuring.

The menu structure is left almost intact, except that indention is
fixed in most cases. Most visible are the INET changes where several
"depends on INET" are replaced with a single ifdef INET / endif pair.

Several new files were created to accomplish this change - they are
small but serve the purpose that config options are now distributed
out where they belongs.

+	---help---
+	  Econet is a fairly old and slow networking protocol mainly used by
+	  Acorn computers to access file and print servers. It uses native
+	  Econet network cards. AUN is an implementation of the higher level
+	  parts of Econet that runs over ordinary Ethernet connections, on
+	  top of the UDP packet protocol, which in turn runs on top of the
+	  Internet protocol IP.
+
+	  If you say Y here, you can choose with the next two options whether
+	  to send Econet/AUN traffic over a UDP Ethernet connection or over
+	  a native Econet network card.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called econet.
+
+config ECONET_AUNUDP
+	bool "AUN over UDP"
+	depends on ECONET
+	help
+	  Say Y here if you want to send Econet/AUN traffic over a UDP
+	  connection (UDP is a packet based protocol that runs on top of the
+	  Internet protocol IP) using an ordinary Ethernet network card.
+
+config ECONET_NATIVE
+	bool "Native Econet"
+	depends on ECONET
+	help
+	  Say Y here if you have a native Econet network card installed in
+	  your computer.
