[REQ] C generator: access to body and status

Is your feature request related to a problem? Please describe.

With the C generator, returned data is lost when response_code != 200.

Describe the solution you'd like

When using C generated code, I would like to have access to apiClient->response_code and
apiClient->dataReceived when response_code is not 200.

Describe alternatives you've considered

With the python generated code, whenever response_code is not 200, an exception is raised. The exception has fields containing:
self.status = http_resp.status
self.reason = http_resp.reason
self.body = http_resp.data
self.headers = http_resp.getheaders()

Additional context

YAML that can be used for an example:

Use the supplied OpenAPI YAML to generate a C client and inspect the generated response-handling path, especially the apiClient response_code and dataReceived fields. Reproduce a non-200 response and define done as preserving access to its status and body, including for responses such as 300, 400, and default.
