Read 0-terminated string.

@param h the IO handle to read from @param what describes what is being read (for error message creation) @param result where to store the pointer to the (allocated) string (note that *result could be set to NULL as well) @param max_length maximum allowed length for the string @return #GNUNET_OK on success, #GNUNET_SYSERR on failure
