Extending WifiSSLClient

brentru commented 5 years ago

This pull request extends the functionality of WiFiSSLClient to include a new, optional, way of establishing a secure SSL connection with a server. Users can now connect with a server either with a CA certificates, or a CA certificate and user-defined certificate and private key.

Users can now provide a X.509 certificate and private key from CircuitPython's ESP32SPI library to WiFiSSLClient via the CommandHandler's setClientCert and setCertKey (TODO, link to ESP32SPI PR)
WiFiSSLClient now handles timeouts
- Add configurable SSL handshake timeout to WiFiSSLClient
Added debugging to WiFiSSLClient, more verbose errors.
Errors during establishing a connection now return
Added personalization context for mbedtls_ctr_drbg_seed.
Added development workflow-related modifications to Makefile to allow for using a SAMD51 board as a passthrough.
Firmware bumped to v1.4.0

FWIW - I have built this using the 3.3 IDF and loaded it onto a PyPortal and a Huzzah ESP32 feather. Both run the esp32spi_simpletest OK.
Does not appear to break anything! Next I'll try to figure out how to actually use the new stuff and run a few more tests.

Just curious -are you planning to use the 3.2 IDF or 3.3 for the "production run"

the combine.py file needs to be updated to change the name of the combined file. It still uses 1.3.1

@jerryneedell Thanks for testing if it broke anything.

Thanks, updated to reflect 1.4.0.

3.2, I think we should update nina-fw to ESP-IDF v3.3 in the future, though, I haven't yet looked at what the major diffs are.
