[MAC80211]: split out some key functions from ieee80211.c
into a new file key.c which doesn't have much code right now but it makes ieee80211.c easier to read. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
