The basic problem is that the DRC engine does length testing and skew
testing by collecting all the diff pair constituent parts and pairing them
itself. Since each part is collected on its own, we need to ignore the
'B' unit when evaluating any conditional expressions. However, doing this
in general means that when evaluating "OwnClearance()" we also ignore the
'B' unit and return the diff pair CLEARANCE_CONSTRAINT when we shouldn't.
This implements a more discerning test which know what the current requested
constraint is when evaluating expressions.

A triangular trapezoid will have the deltaX/deltaY of the same size as
the length of that axis. This creates a three-point polygon, which is
perfectly valid for our use
When building the connectivity database, we should not be using the
connectivity to check for shapes.
To make this deterministic, we introduce two flags (ALWAYS_FLASH and
NEVER_FLASH) that are used with connectivity building to determine
whether a pad is flashed for connectivity or not. ZONE <-> PAD/VIA
connectivity will be checked with ALWAYS_FLASHED and all other
connectivity will be checked with NEVER_FLASHED if they are marked for
potential annular ring removal. If they are not marked for removal,
they will be checked ALWAYS_FLASHED.

Allow falling back to the alternate variable definitions if the built-in

Fixes https://gitlab.com/kicad/code/kicad/issues/11168
Arcs can be altered by the process of changing from on-disk
representation to in-memory representation. Saving back to disk without
modifying the arc should not modify the calculated values.
This stores a copy of the on-disk representation that is only used to
save back to disk in the event that the arc is not modified during
editing.

Avoid excess writes to the project directory to dodge issues with remote

1) Drop tiny islands which might cause connection problems.
2) Cleanup some dead code in filler
3) Don't estabilish a connection to an island that is fully covered
by whatever its connecting to.
