- nfc_device is now an opaque type; - PN53x specific errors are not public anymore; - nfc_device_name() renamed to nfc_device_get_name() for the sake of consistency; - examples/*, utils/* uses the new nfc_device_get_name() function instead of access directly to struct's content; - new error defined: NFC_ERFTRANS for notifying about RF transmission error, its used by mifare.c to detect permissions error on mifare; - drivers initiator_transceive_bytes() function now returns libnfc's error code on failure (<0), and received bytes count on success (>=0); - remove some unused errors.
