This introduces layer handling to a lot of the geometry routines.
Many of them don't do much with it now, but it does help multi-layer
zones and will help when padstacks are implemented.
When running a hit test to check if the anchors are connected, we should
loosen the check for tracks to account for the width. Otherwise
connected anchors can be connected in the system but test positive for
IsDangling()

Each time we iterator through the tracks list to merge, we change the
connectivity system and can leave possible merges. By iterating, we
keep merging until we cannot anymore.

There are cases where you will want to keep vias that only connect to
one layer but still want to cleanup tracks. As distinct entities, they
are given their own checkboxes and actions
Fixes https://gitlab.com/kicad/code/kicad/issues/5019
Remove extraneous use of FLAG0 from tracks cleaner (it was checked but
never set).
Fix issue in expand connections where two parts of it couldn't agree
on the same flag (BUSY vs SKIP_STRUCT), and where the second part was
clearing the flag instead of setting it.
Remove obsolete HIGHLIGHT infrastructure (we now use selection).
Remove extraneous use of BUSY flag in several places (it was never
set).
Removing items from the structure will invalidate the iterators so we
need to either stage the deletions or keep a duplicate structure for the
iteration.

This end was not detected as connected by the IsDangling method.
Fix incorrect cleaning of dangling tracks in track cleaner.
Remove also a dead code.
The merge co-linear track segments is still full bugged in track cleaner.
Fixes a few commit issues based on the std:: rework. Add an option to
delete tracks fully in pads and makes merge tracks smarter
