This patch cleans up a number of things:
 * the unusable definition of the HT capabilities/HT information
   information elements
 * variable names that are hard to understand
 * mac80211: move ieee80211_handle_ht to ht.c and remove the unused
             enable_ht parameter
 * mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht
 * mac80211: fix bug with casting the result of ieee80211_bss_get_ie
             to an information element _contents_ rather than the
             whole element, add size checking (another out-of-bounds
             access bug fixed!)
 * mac80211: remove some unused return values in favour of BUG_ON
             checking
 * a few minor other things

Also remove a few stray DECLARE_MAC_BUF that were no longer
used at all.

This patch changes mac80211 to share some more data about
stations with drivers. Should help iwlwifi and ath9k when
 they get around to updating, and might also help with
implementing rate control algorithms without internals.

There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

The ieee80211_sta_tx function isn't MLME code any more,
it's getting used by a lot of code. Move it to utils and
rename it to ieee80211_tx_skb.

The aggregation handling isn't dependent on anything related to our
STA-mode implementation, and doesn't need to depend on it for frame
processing. This patch moves the relevant code to ht.c and adds a
hook in rx.c. For now, the relevant action frames are only processed
in STA/IBSS modes, but that's now something we can easily change.

Now that I've created ht.c, I can move the aggregation
code from main.c into it.

Some of the HT code in mlme.c is misplaced:
 * constants/definitions belong to the ieee80211.h header
 * code being used in other modes as well shouldn't be there
