Implement asio-ssl layer with three classes in asio::ssl::mbedtls: * context -- replaces SSL_CTX, used mainly as a container to options, certs, keys * engine -- replaces SSL, implements the actual mbedtls operations * bio -- implements openssl BIO specifically tailered to mbedtls and its asio usage Further updates: * asio: Used shared_ptr<> for bio pairs * asio: Add error checks to mbedtls-bio * asio: Address potential ssl-context ownership issue * asio: Address potential bio-engine ownership issue

The ASIO support multiple backend TLS libraries. Currently the mbedTLS with a thin ESP-OpenSSL
|
|
port layer (default choice) and WolfSSL are supported.
|
|
Different TLS libraries may support different features and have different resource
|
|
usage. Consult the ESP-TLS documentation in ESP-IDF Programming guide for more details.

Size in bytes of SSL-BIO implementation.

Reducing the BIO size saves more RAM, but may slow down input output operations due to
|
|
fragmentation.
