da07b2b4a7 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.

aceb141d2b wpa_supplicant: Adding SAE modules with testcase
This change ports SAE(Simultaneous Authentication of Equals)
feature from wpa_supplicant and makes it work with mbedtls
crypto APIs. Currently only group 19 is supported. A sample
SAE handshake is included in the testcase. Other minor
changes for DH groups are also included.

9ec363a25d wpa_supplicant: Make internally used crypto headers private
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.

Closes IDF-476

80a5bd8e54 wpa_supplicant: Port more crypto functions to use mbedtls
Use mbedtls PBKDF2 and SHA1 for faster calculations during four-way
handshake.

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.

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

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
