Refactor result retrieval in C API
The result retrieval functions get_with_array_result, get_with_string_result, get_with_result and get_without_result currently contain much duplicated code: the error handling. This patch tries to simplify this code by introducing a new function, get_with_status, that executes a function, catches errors and returns the error code together with the result of the function or a fallback value passed by the user if the function failed. get_with_array_result, get_with_string_result and get_with_result are adapted to use this function. get_without_result is not changed as it has a different error handling logic than the other functions: It ignores any InvalidCRCReceived exceptions.
