Updated wolfSSL to v5.7.2

[frankencode]

Change summary:

• Updated the git submodule of wolfSSL to the latest version
• Copied over benchmark and test code from wolfssl/wolfssl package of ESP-IDF app store
• Copied and extended user_config.h from wolfssl/wolfssl package of ESP-IDF app store
  • Disabled ASN_TIME (because system time is uncertain on an ESP32)
  • Added options to enable BER based certificates
  • Enabled multi-threading
  • Disabled SHA hardware acceleration for stability reason
• I ran tests and benchmarks to verify correctness on an ESP32S3

wolfSSL is also supported as a Managed Component: https://components.espressif.com/components/wolfssl/wolfssl

There's an example of a flexible CMakeLists.txt for wolfSSL in the template example, including a user_settings.h file.

See espressif/esp-idf#13966

@frankencode check out my latest components/wolfssl/Kconfig that you may be interested in using.

Thanks Jim! That's a lot of configure flags! I'll try to merge some from your user_settings/Kconfig when time allows. Another thing I wanted to do is to port the tests to pytest as used by other esp-idf components.. Furthermore I had to do some workarounds in the user_settings when removing "SINGLE_THREADED". You might want to check this out at the end of my user_settings.

Hi @frankencode - that's interesting. I recall some time ago there was a problem with pthread.h. I thought that was resolved and addressed in settings.h but I don't see anything there.

I've not personally encountered that recently. I'll take a look. Thanks for the heads up.

In the meantime, you may also be interested in wolfSSL/wolfssl#7953; There I've moved some of the common config user_settings.h detection to the common settings.h

@frankencode I've not been able to reproduce any compiler errors related to the #include <pthread.h> and wolfSSL SINGLE_THREADED topic. What version of the ESP-IDF are you using? What, exactly, is the error you are seeing?

Other areas of interest:

• internal.h
• types.h
• wc_port.c
• wc_port.h

@gojimmypi Yes, I moved last week to latest ESP-IDF 5.4 and it compiles now without further issues when I comment out SINGLE_THREADED. A workaround in user_settings.h is not needed anymore.
