Previously significant parts of tuplesort.c were untested. This commit, while not testing every path, significantly increases coverage. In particular, this adds tests for abbreviated key logic, forward/backward scans & scrolling and mark/restore. I tried to keep the table sizes reasonable, and stress the on-disk paths by setting work_mem to low values for specific tests. The buildfarm will tell whether more attention to test time is needed.
