Actually computes the differences between the data models for which comp is defined.
For each difference computed, stored in a #GdaDiff structure, the "diff-computed" signal is emitted.
If one connects to this signal and returns FALSE in the signal handler, then computing differences will be
stopped and an error will be returned.
