wireless: disable wext sysfs by default 

This code has been on the list to remove for a long
time, so disable it by default, add a warning to its
Kconfig, and schedule it for removal in 3.5.

The only known dependency, hal, has not required it
since its 0.5.12 release, which was in early 2009
and hal has since been deprecated completely.

This option enables the deprecated wireless statistics
files in /sys/class/net/*/wireless/. The same information
is available via the ioctls as well.
Say Y if you have programs using it, like old versions of
hal.
Say N. If you know you have ancient tools requiring it,
like very old versions of hal (prior to 0.5.12 release),
say Y and update the tools as soon as possible as this
option will be removed soon.
