Previous interfaces for these libcurl internal functions did not allow to tell apart a legitimate zero size result from an error condition. These functions now return a CURLcode indicating function success or otherwise specific error. Output size is returned using a pointer argument. All usage of these two functions, and others closely related, has been adapted to the new interfaces. Relative error and OOM handling adapted or added where missing. Unit test 1302 also adapted.
