This patch fixes some of the ieee80211 crypto related code so that
instead of having the host fully do crypto operations, the host_build_iv
flag works properly (for WEP in this patch) which, if turned on,
requires the hardware to do all crypto operations, but the ieee80211
layer builds the IV. The hardware also has to build the ICV.
Previously, the host_build_iv flag couldn't be used at all for WEP, and
not alone (with both host_decrypt and host_encrypt disabled) because the
crypto algorithm wasn't assigned. This is also fixed.
I have tested this patch both in host crypto mode and in hw crypto mode
(with the Broadcom chipset).
[resent, signing digitally caused it to be MIME-junked, sorry]

The functions ieee80211_wx_{get,set}_encodeext fail if one tries to set
unicast (IW_ENCODE_EXT_GROUP_KEY not set) keys at key indices>0. But at
least some Cisco APs dish out dynamic WEP unicast keys at index !=0.

Changed crypto method from requiring a struct ieee80211_device reference
to the init handler. Instead we now have a get/set flags method for
each crypto component.
Setting of TKIP countermeasures can now be done via
set_flags(IEEE80211_CRYPTO_TKIP_COUNTERMEASURES)

Allow drivers to fix an issue when using wpa_supplicant with WEP.
The problem is introduced by the hwcrypto patch. We changed indicator of
the encryption request from the upper layer (i.e. wpa_supplicant):
In the original host based crypto the driver could use: crypt &&
crypt->ops.
In the new hardware based crypto, the driver should use the flags
specified in ieee->sec.encrypt.

Fixed a kernel oops on module unload by adding spin lock protection to
ieee80211's crypt handlers (thanks to Zhu Yi)
Modified scan result logic to report WPA and RSN IEs if set (vs.being
based on wpa_enabled)
Added ieee80211_device as the first parameter to the crypt init()
method. TKIP modified to use that structure for determining whether to
countermeasures are active.

No code changes, just Lindent + manual fixups.
This prepares us for updating to the latest Intel driver code, plus
gives the source code a nice facelift.
