wanrouter: completely decouple obsolete code from kernel. 

The original suggestion to delete wanrouter started earlier
with the mainline commit f0d1b3c2bc
("net/wanrouter: Deprecate and schedule for removal") in May 2012.

More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39 ("netdevice wanrouter: Convert directly reference of
netdev->priv").  So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.

This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.

Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

Connect LAN to WAN via Linux box.
Select driver your card and remember to say Y to "Wan Router."
You will need the wan-tools package which is available from
<ftp://ftp.sangoma.com/>.
Note that the answer to this question won't directly affect the
kernel except for how subordinate drivers may be built:
saying N will just cause the configurator to skip all
the questions about WAN router drivers.
If unsure, say N.

---help---
Cyclom 2X from Cyclades Corporation <http://www.avocent.com/> is an
intelligent multiprotocol WAN adapter with data transfer rates up to
512 Kbps. These cards support the X.25 and SNA related protocols.
While no documentation is available at this time please grab the
wanconfig tarball in
<http://www.conectiva.com.br/~acme/cycsyn-devel/> (with minor changes
to make it compile with the current wanrouter include files; efforts
are being made to use the original package available at
<ftp://ftp.sangoma.com/>).
Feel free to contact me or the cycsyn-devel mailing list at
<acme@conectiva.com.br> and <cycsyn-devel@bazar.conectiva.com.br> for
additional details, I hope to have documentation available as soon as
possible. (Cyclades Brazil is writing the Documentation).
The next questions will ask you about the protocols you want the
driver to support (for now only X.25 is supported).
If you have one or more of these cards, say Y to this option.
To compile this driver as a module, choose M here: the
module will be called cyclomx.

Connect a Cyclom 2X card to an X.25 network.
Enabling X.25 support will enlarge your kernel by about 11 kB.
