tcp_transport: Fix error propogation 
- Made tcp_transport_errors codes public to indicate
  TCP connection issues not covered in socket's errno
- Added API to translate tcp_transport_error codes
  to esp_err_t codes for TCP Transport

For better control over connection timeouts
To be in line with former tcp_transport, as esp-tls is not used for
plain tcp transports

David Cermak 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)

David Cermak ce519ee783 tcp_transport: Extend transport error storage for socket error 
Everytime we report error and log errno, we also capture the actual
errno to an internal storage so that user application can retrieve
its value.

David Cermak 5e9f8b52e7 tcp_transport: Added internal API for underlying socket, used for custom select on connection end for WS 
Internal tcp_transport functions could now use custom socket operations.
This is used for WebSocket transport, when we typically wait for clean
connection closure, i.e. selecting for read/error with expected errno or
recv size=0 while socket readable (=connection terminated by FIN flag)
