f249ddd9ae esp_transport: Use tcp_connect from esp_tls for plain TCP 
so we don't have to allocate esp_tls structure (~2KB) to save heap when using plain TCP connection

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.

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)

420aef1ffe Updates for riscv support 
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
  longer signed/unsigned int).

Changes come from internal branch commit a6723fc

52469c8505 esp-tls: enable TLS renegotiation using explicit API call 
mbedTLS stack does not keep TLS renegotiation enabled even if
relevant config option is turned on, it needs explicit API call
`mbedtls_ssl_conf_renegotiation` to do so.

This issue was observed in case of Azure IoT, where keys needs to
be refreshed periodically to keep TLS connection intact.

Even `esp_wolfssl_write` API considers just negative returns as errors.

7f35c4ff3e esp-tls: Basic structure 
Purpose:
1. TLS calls can be too many, and require a user to know the expected behaviour. A simple TLS socket wrapper that can be used in any higher level protocol.
2. Uses OpenSSL compatibility layer, so applications using esp-tls can be built on the host, and it should just work on ESP
