The root cause was not removing the original (pre-dragging) via from the world, comparing the ITEM::Parent() pointers of the items was only hiding the main issue.
This also fixes the PNSViaCollisions test in the qa/ suite.
The previous test didn't handle is-self-tests between a hole and
its override in a different NODE. When calculating the pushout
force we don't remove the via (and its hole) from the current
node until after the calculation, so we end up checking for
collisions between the new (cloned) via's hole and the original
hole in the root node.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/14795
About 1/3 of callers to Parent() don't care if they get the immediate
parent or not, about 1/3 want only the immediate parent, and about 1/3
want the hole parent's Parent().
I had earlier changed PNS::ITEM::HOLE to override Parent() and return
the hole parent's Parent(), but since the callers are pretty evenly
split I've reverted that and added BoardItem() for callers who want the
eventual BOARD_ITEM (whether a direct parent or a grandparent).
(Also removes a dead routine so I didn't have to figure out which of
the two it wanted....)
- LINEs now own their vias optionally (depending whether a LINE with its VIA belongs to a node)
- get rid of unique_ptr on the internal NODE::Add API (and also made it private)
- make sure stack pointers are not added to the node
- use rvalue reference for NODE::Add/NODE::Replace

- prerequisite for holes as first class objects code
- introduced the OWNABLE_ITEM interface that defines the owning container (NODE/other ITEM/ITEM_SET)
- simplified the ITEM_SET interface
- constified a lot of APIs (ownership/JOINT management) as a side effect
Rebased and cleaned up by Jeff Young <jeff@rokeby.ie> 5 April 2023
- some STL cover types removed
Also checks the nets when checking for a pad being flashed on a particular
layer (so we don't end up thinking the currently-routing-collided track
is a connection).
add overloads for NODE::Add( ... ) taking pointers to specific item types (retain old private add-Functions, they will come in handy later)
LINE overloads now take by reference, to document their special treatment.
updated code throughout affected by these changes
- PNS_ITEMSET now keeps ownership info (does not rely on PNS_ITEM::Owner(), avoiding the risk of dangling pointers)
- fixed vias losing connected traces when dragging in mark obstacles mode
- fixed rare segfault when board item returned null netclass
