This commit add following crypto changes
1. Update current crypto code with upstream supplicant code
2. Add a proper porting layer to use mbedtls APIs for all the crypto
operations used by supplicant.
Internal crypto will be used when USE_MBEDLTS flag is disabled
in supplicant's menuconfig.
This commit also removes the clutter in crypto files due to partial
porting of some APIs to mbedtls, all the code from those files have
been removed and rewritten in a generic way, this is inspired from
current upstream code.
This also reduces the lib size significantly, supplicant's lib
size reduces around ~567kb after this change(NB: lib size doesn't
indicate reduction in final bin size).
Removed the old dynamically allocated GDMA channel approach.
It proved too unreliable as we couldn't not ensure consumers of the mbedtls
would properly free the channels after use.
Replaced by a single shared GDMA channel for AES and SHA, which won't be
released unless user specifically calls API for releasing it.
MbedTLS: Add software fallback for Modular Exponentiation for larger bignum operations
Closes WIFI-3257 and IDFGH-132
See merge request espressif/esp-idf!11928
Add configuration option to fallback to software implementation
for exponential mod incase of hardware is not supporting it
for larger MPI value.
Usecase:
ESP32C3 only supports till RSA3072 in hardware. This config option
will help to support 4k certificates for WPA enterprise connection.
RX process caches the session information in "ssl->in_ctr" not in "ssl->in_buf".
So when freeing the SSL, can't free the "ssl->in_ctr", because the "ssl->in_buf"
is empty.
Make the RX process like TX process, and cache the session information in
"ssl->in_buf", so that the cache buffer can be freed when freeing the SSL.
Closes https://github.com/espressif/esp-idf/issues/6104
DMA process didnt wait for idle before returning.
This meant that there was a potential for the dma
descriptors which were on the stack to be reclaimed
before the DMA operation finished.
Note: besides the esp-netif component, this commit also disables
net_sockets.c from mbedtls, which is one of the base components and uses BSD API (not specifically lwIP). This might be refactored to use CONFIG_SUPPORT_BSD_API instead of CONFIG_ESP_NETIF_TCPIP_LWIP
in the future.
It also disables smartconfig_ack.c and wifi_init.c from esp_wifi
component for referencing some lwIP config options (smartconfig_ack.c changes might be also
updated to check CONFIG_SUPPORT_BSD_API)

Fixed MBEDTLS_SSL_PROTO_TLS1_1 still being defined even ifCONFIG_MBEDTLS_SSL_PROTO_TLS1_1 is not

* Replaced crypotoauthlib with esp-cryptoauthlib
* Added menuconfig option for esp-tls about using HSM
* Added error codes for HSM in esp-tls,
* Added support to select different type of ATECC608A chips
* Added README, updated docs
* tcp_transport: Added option to enable secure_element for ssl
Closes https://github.com/espressif/esp-idf/issues/4432
* Add options to mbedtls for hardware acceleration
* Disable mbedtls EC curves if hardware acceleration is selected
since the hardware will have to define the curves supported
* Add a hardware ecdsa example
Earlier check was for only input buffer but it is quite likely to have
output buffer also from non-DMA memory range and hence requirement to
reallocate and then copy data from AES engine.
