[TRIAL BALLOON] remove rtnetlink wext

[Johannes Berg <johannes@sipsolutions.net>]

This patch removes rtnetlink wireless extensions. The rtnetlink
transport for wireless extensions is
 * a fairly large chunk of code
 * not enabled on most kernels
 * not required by any userspace tools
 * only about a year old
 * pointless

Thus, removing this code seems feasible.
