WFD: Add Wi-Fi Display support This commit adds control interface commands and internal storage of Wi-Fi Display related configuration.

WMM cleanup (WME -> WMM rename, comments, etc.) This updates the terminogy to match with the final WMM specification. In addition, some of the WMM TSPEC structure fields were in incorrect order and used without byte order swapping. Those are also taken care of this cleanup patch.

Added preliminary Wi-Fi Protected Setup (WPS) implementation This adds WPS support for both hostapd and wpa_supplicant. Both programs can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN methods are supported. Currently, hostapd has more complete configuration option for WPS parameters and wpa_supplicant configuration style will likely change in the future. External Registrars are not yet supported in hostapd or wpa_supplicant. While wpa_supplicant has initial support for acting as an Registrar to configure an AP, this is still using number of hardcoded parameters which will need to be made configurable for proper operation.

Fixed MFP Association Comeback mechanism to use Timeout Interval IE The separate Association Comeback Time IE was removed from IEEE 802.11w and the Timeout Interval IE (from IEEE 802.11r) is used instead. The editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but still, the use of Timeout Interval IE is the expected mechanism.

FT: Add RIC Request generation and validation (but not processing) This adds first part of FT resource request as part of Reassocition Request frame (i.e., FT Protocol, not FT Resource Request Protocol). wpa_supplicant can generate a test resource request when driver_test.c is used with internal MLME code and hostapd can verify the FTIE MIC properly with the included RIC Request. The actual RIC Request IEs are not processed yet and hostapd does not yet reply with RIC Response (nor would wpa_supplicant be able to validate the FTIE MIC for a frame with RIC Response).
