4375f888fa esp-tls: Fix wolfssl error codes for WANT_READ/WANT_WRITE
wolfSSL error codes are mostly positive numbers, but esp-tls potentially
non-block API (read/write) returns ssize_t, i.e. bytes read/written if
>0, errorcode otherwise. To comply with this API we have to conditionate
the wolfssl return codes to negative numbers, preferably the same codes
as mbedTLS codes.

6b318fe583 esp_tls: Updated connection method to use non-blocking connect
For better control over connection timeouts
To be in line with former tcp_transport, as esp-tls is not used for
plain tcp transports

391d7bf271 tcp_transport: Add TCP transport connection errors
Transport's error_handle is used to capture different types of errors
including esp_err_t from esp-tls and socket/system errors.
This change adds the following error codes for TCP transport:
* connection closed by a FIN flag (clean closure from server)
* DNS resolution problem
* connection timeout
These errors are already defined in esp-tls component and since this
component will be used in the future for both TCP and SSL transport, we
currently report these issues in transport::error_handle::esp_tls_last_error
of standard esp error type (esp_err_t)

Closes https://github.com/espressif/esp-mqtt/issues/182
