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.

2d25252746 esp-tls: Rework tcp_connect() to use more subroutines
Refactored the esp_tcp_connect() functionality to break it down to
* dns-resolution + socket creation
* set configured socket options
* set/reset non-block mode
* the actual connection in non-blocking mode

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)

ca964dfbcc esp-tls: Changed default behaviour for esp-tls client ( for security
purpose)
        By default esp-tls client will now return error if no server verify option
        is provided, earlier it used to skip the verification by
        default.
        Added config option to skip server verification by default (for testing
        purpose)
        Updated required docs

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.

60dc4285f4 Fixed esp_tls_conn_write documentation.
Return value `0` in actual is case of partial write and not error as per `mbedtls_ssl_write`
Modified documentation of `esp_tls_conn_write` accordingly.

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