Deng Xin c139683024 supplicant/esp_wifi: move supplicant to idf
Move supplicant to idf and do following refactoring:
1. Make the folder structure consitent with supplicant upstream
2. Remove duplicated header files and minimize the public header files
3. Refactor for WiFi/supplicant interfaces

/**
* set_key - Configure encryption key
* @ifname: Interface name (for multi-SSID/VLAN support)
* @priv: private driver interface data
* @alg: encryption algorithm (%WPA_ALG_NONE, %WPA_ALG_WEP,
* %WPA_ALG_TKIP, %WPA_ALG_CCMP, %WPA_ALG_IGTK, %WPA_ALG_PMK);
* %WPA_ALG_NONE clears the key.
* @addr: address of the peer STA or ff:ff:ff:ff:ff:ff for
* broadcast/default keys
* @key_idx: key index (0..3), usually 0 for unicast keys; 0..4095 for
* IGTK
* @set_tx: configure this key as the default Tx key (only used when
* driver does not support separate unicast/individual key
* @seq: sequence number/packet number, seq_len octets, the next
* packet number to be used for in replay protection; configured
* for Rx keys (in most cases, this is only used with broadcast
* keys and set to zero for unicast keys)
* @seq_len: length of the seq, depends on the algorithm:
* TKIP: 6 octets, CCMP: 6 octets, IGTK: 6 octets
* @key: key buffer; TKIP: 16-byte temporal key, 8-byte Tx Mic key,
* 8-byte Rx Mic Key
* @key_len: length of the key buffer in octets (WEP: 5 or 13,
* TKIP: 32, CCMP: 16, IGTK: 16)
*
* Returns: 0 on success, -1 on failure
*
* Configure the given key for the kernel driver. If the driver
* supports separate individual keys (4 default keys + 1 individual),
* addr can be used to determine whether the key is default or
* individual. If only 4 keys are supported, the default key with key
* index 0 is used as the individual key. STA must be configured to use
* it as the default Tx key (set_tx is set) and accept Rx for all the
* key indexes. In most cases, WPA uses only key indexes 1 and 2 for
* broadcast keys, so key index 0 is available for this kind of
* configuration.
*
* Please note that TKIP keys include separate TX and RX MIC keys and
* some drivers may expect them in different order than wpa_supplicant
* is using. If the TX/RX keys are swapped, all TKIP encrypted packets
* will tricker Michael MIC errors. This can be fixed by changing the
* order of MIC keys by swapping te bytes 16..23 and 24..31 of the key
* in driver_*.c set_key() implementation, see driver_ndis.c for an
* example on how this can be done.

/**
* send_eapol - Optional function for sending EAPOL packets
* @priv: private driver interface data
* @dest: Destination MAC address
* @proto: Ethertype
* @data: EAPOL packet starting with IEEE 802.1X header
* @data_len: Size of the EAPOL packet
*
* Returns: 0 on success, -1 on failure
*
* This optional function can be used to override l2_packet operations
* with driver specific functionality. If this function pointer is set,
* l2_packet module is not used at all and the driver interface code is
* responsible for receiving and sending all EAPOL packets. The
* received EAPOL packets are sent to core code with EVENT_EAPOL_RX
* event. The driver interface is required to implement get_mac_addr()
* handler if send_eapol() is used.
