Updated regression tests for output change in r5974 and improved handling of

cores.

- test/structure, test/del_vec, test/frame_ref, test/meas_qual, test/del_frame:
  added newline after "unit" directive (reported by Xiangfu Liu)
- test/Common: new function expect_sed for post-processing of test output
- test/tsort: use expect_sed to ignore "(core dumped") after "Aborted"
- test/Common: if there is a file called "core", don't run it
- Makefile (clean): remove test/core
