e1ee6b600b WPS: Add support for NFC out-of-band mechanism 
The new file wps_nfc.c and ndef.c implements NFC device independent
operation, wps_nfc_pn531.c implements NFC device dependent operation.

This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar

Following NFC methods can be used:
- Enrollee PIN with NFC
- Registrar PIN with NFC
- unencrypted credential with NFC

Encrypted credentials are not supported.

Enrollee side operation:

Registrar side operation:

Example configuration.
CONFIG_WPS=y
CONFIG_WPS_NFC=y
CONFIG_WPS_NFC_PN531=y

I used NFC device "NXP PN531". The NFC device access method is
confidential, so I used outer library. Please download below files from
https://www.saice-wpsnfc.bz/index.php

<WiFi test>
The hostapd/wpa_supplicant with this patch passed below tests on
"Wi-Fi WPS Test Plan Version 1.6".
4.2.5 Add device using NFC Method with password token
(I used SONY STA instead of NXP STA.)

4.2.6 Add device using NFC Method with configuration token

5.1.9 Add to AP using NFC Method with password token
through internal registrar
(I used SONY AP instead of NXP AP.)

5.1.10 Add to AP using NFC Method with configuration token
through internal registrar

7cbf51bbd8 WPS UFD: Remove oob_dev pointer from wps_context 
This pointer and the especially the oob_dev->device_path does not remain
valid, so better not save it any longer than it is needed.

1b39bad109 WPS UFD: Handle scandir() error and no matches results differently 
Better make sure there are no memory leaks in case of 0 entries
found. In addition, the error string may be of use in the error case.

e7f3c1f436 WPS UFD: Define macros for the UFD directory templates 
This allows the UNIX vs. DOS path separators to be handled in the build.

70e070461d WPS UFD: Use private data structure for oob_device_data 
This gets rid of global variable use and may be needed to allow
concurrent access in some case if the interface is extended.

46bdb83acd WPS: Add UFD support (USBA out-of-band mechanism) 
This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar

Following UFD methods can be used:
- Enrollee PIN with UFD
- Registrar PIN with UFD
- unencrypted credential with UFD

Encrypted credentials are not supported.

Enrollee side operation:
wpa_cli -i ath0 wps_oob <device type> <mount point> <oob method>
    oob method = pin-e/pin-r/cred

wpa_cli -i ath0 wps_oob ufd /mnt/ pin-r

Registrar side operation:
./hostapd_cli -i ath0 wps_oob <device type> <mount point> <oob method>
    oob method = pin-e/pin-r/cred

hostapd_cli -i ath0 wps_oob ufd /mnt/ cred
