Add preliminary IEEE 802.11n support into hostapd
This commit brings in cleaned up version of IEEE 802.11n implementation from Intel (1). The Intel tarball includes number of other changes, too, and only the changes specific to IEEE 802.11n are brought in here. In addition, this does not include all the changes (e.g., some of the configuration parameters are still missing and driver wrapper changes for mac80211 were not included).
