[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---
+ The DECnet networking protocol was used in many products made by
+ Digital (now Compaq). It provides reliable stream and sequenced
+ packet communications over which run a variety of services similar
+ to those which run over TCP/IP.
+
+ To find some tools to use with the kernel layer support, please
+ look at Patrick Caulfield's web site:
+ <http://linux-decnet.sourceforge.net/>.
+
+ More detailed documentation is available in
+ <file:Documentation/networking/decnet.txt>.
+
+ Be sure to say Y to "/proc file system support" and "Sysctl support"
+ below when using DECnet, since you will need sysctl support to aid
+ in configuration at run time.
+
+ The DECnet code is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module is called decnet.
