kernel: placement, history, mesh-memo, display and issue tests read the record

Browse Source 
- placement: a rigid placement moves the record and nothing else (regions, shells, loops
  with their pcurves, edges and their uses equal; every vertex moved; the identity's
  history), on a cylinder whose wall's loop uses its seam twice.
- issue 2005, 616, 674, 1038, 1510, join between caps, regularization protection, history,
  mesh memo, display mesh: the truck reads become record reads (shells closed by edge
  uses, faces by the record's surfaces, vertices by the record's points, the mesher's own
  boundary budget); the nearly-in-plane slab of 1510 is an extruded record body.
- Deleted, testing internals that are gone: issue 616's glue_joins_every_face_the_pieces_share
  (coplanar::glue) and the_retry_guard_refuses_changes_away_from_the_tool
  (boolean_guard::check_retry); issue 674's partial_contact_does_not_join_tangent_or_separated_faces
  (coplanar::imprint_union); issue 1038's hinted_division_matches_the_search_from_nothing
  (truck's vendored parameter_division); issue 1510's a_face_close_to_the_plane_but_off_it_is_not_moved
  (ops::off_plane). The boolean-diagnostics assertions (no retry, no tool nudge) went with
  capture_boolean_diagnostics; the rest of each test is kept.
