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.
