db5f01429f wpa_supplicant: Fix memory leaks in WPA3 connection
1. Buffers for SAE messages are not freed after the handshake.
   This causes memory leak, free buffers after SAE handshake.
2. SAE global data is not freed until the next WPA3 connection
   takes place, holding up heap space without reason. Free theis
   data after SAE handshake is complete or event fails.
3. Update wifi lib which includes memory leak fix during BIP
   encryption/decryption operations.

4557c686b8 wpa_supplicant: Fix EAP Re-authentication issue
EAP reauth frames are dropped at various stages due to current
implementation of WPA2 ENT states and EAP SM init/deinit logic.
Route EAPOL frames based on EAP pkt type and maintain EAP SM
to facilitate EAP re-authentication process.

6b76228fcb wpa_supplicant: Add SAE handshake support for WPA3-PSK
Under WPA3-Personal, SAE authentication is used to derive PMK
which is more secure and immune to offline dictionary attacks.
1. Add modules to generate SAE commit/confirm for the handshake
2. Add modules that build and parse SAE data in Auth frames
3. Add WPA3 association and key mgmt definitions
4. Invert y-bit while solving for ECC co-ordinate -
     Once an X co-ordinate is obtained, solving for Y co-ordinate
     using an elliptical curve equation results in 2 possible values,
     Y and (P - Y), where p is the prime number. The co-ordinates are
     used for deriving keys in SAE handshake. As par the 802.11 spec
     if LSB of X is same as LSB of Y then Y is chosen, (P - Y) otherwise.
     This is not what is implemented, so fix this behavior to obtain the
     correct Y co-ordinate.

2da4ffa2aa wifi: Add PMK caching feature for station WPA2-enterprise
1) Added PMK caching module from wpa_supplicant.
2) Modified wpa_sm to
    a) Add entry to PMK cache when first time associated to an AP.
    b) Maintain entry across the associations.
    c) Clear current PMKSA when deauth happens.
    d) Search for an entry when re-associating to the same AP and
       set it as current PMKSA
    e) Wait for msg 1/4 from AP instead of starting EAP authentication.
    f) Check PMKID in msg 1 with current PMKSA/cache.
    g) Use the cached PMK to complete 4-way handshake.
3) Remove config_bss callback as it was redundant and used to cause
   problems for PMK caching flow.

a8e0b9171b wpa_supplicant: Fix SAE test-case failure on mbedtls version udpate
Problem:
mbedtls_ctr_drbg_context was initialized in crypto_ec_point_mul. This
was okay in releases before 2.16.4 as entropy_len used to get set to
MBEDTLS_CTR_DRBG_ENTROPY_LEN in function mbedtls_ctr_drbg_seed. The
function is now changed to set the length to
MBEDTLS_CTR_DRBG_ENTROPY_LEN if previous length is 0 and hence the bug.

Solution:
Initialize mbedtls_ctr_drbg_context in crypto_ec_point_mul.

ca80b0445d wpa_supplicant: Make internal crypto headers private (backport v4.0)
A lot of internally used crypto headers are publicly includeable
in user projects. This leads to bug reports when these headers
are incorrectly used or the API's are not used as intended.

Move all crypto headers into private crypto src folder, also move
crypto_ops into Supplicant to remove dependecy on crypto headers.

6b348b94e3 wps: Relax the check on older config methods in case of WPS2.0 (backport
v4.0)

Some APs incorrectly advertize newer WPS2.0 config method bits
without setting bits for the corresponding older methods. This
results in failures during 8-way handshake. Add a workaround to
relax this check so that WPS handshake can proceed.

900df44546 wpa_supplicant: Cleanup fast_xxx modules that use duplicate code
wpa_supplicant is using MbedTLS API's for crypto algorithms. For
calling them a duplicate set of modules is maintained prepended
with 'fast_'. Remove these and use flag USE_MBEDTLS_CRYPTO
instead to separate modules calling MbedTLS API's from native
implementation.

562af8f65e global: move the soc component out of the common list
This MR removes the common dependency from every IDF components to the SOC component.

Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.

In CMAKE, we have two kinds of header visibilities (set by include path visibility):

(Assume component A --(depends on)--> B, B is the current component)

1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)

and we have two kinds of depending ways:

(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)

1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)

1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)

This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:

- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h

The major broken include chain includes:

1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h

some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h
