please test -head - more crypto API cleanups done, WEP TX works again

hi!

i landed 3 diffs a few days ago - one that fixes WEP TX without
reintroducing the original CVE that broke said WEP TX, and two that
refactored how crypto keys are fetched and stored through the ioctl()
layer.

I've tested it on CCMP, TKIP, WEP. All the various pieces worked here,
but of course 802.11 environments are "weird". Thus I'd appreciate any
reports of weird net80211 things on -head that have crept up in the
last week.

Thanks!
