Seth Hillbrand 1a2c9011e6 Rework Copper Sliver check
Adds QA checks to copper sliver tests.  Adds the following checks:
- Dot product between two arms (quickly avoids checks for >90°)
- Checks the sliver is convex (area test)
- Eliminates minor slivers with angles that are approximately 0 and ones
  with the opposite side width beneath a configurable level
- Updates Clipper2 to fix a couple of jagged edges on inflate
- Adds simplify during zone fill inflation to limit jaggies

Jeff Young 03c2850c59 Record parent rule for DRC assertions.
(Particularly important if the rule specified a severity.)

Also fixes a bug looking up LSET layer names in the
GetStandardLayerNames array (which aren't the same).

Seth Hillbrand c18181042f Simplify test for substantial nubs
Substantial elements following a divot should be at least as far in each
cardinal direction from the origin point in order to be considered
substantial.  This catches cases where the "substantial" element is
actually a straight segment away from the divot

Jeff Young 76685ae2d9 Run SILK_CLEARANCE rules on mask layer when testing silk-to-mask clearance.

to-silk clearances).

Seth Hillbrand 7ef5e079fd Smarten connection width checker looking for splits
Fractured polygons are always fractured along the x-axis, so when
checking to see if a segment is a fracture point, we check if the y
coordinate is equal.  This avoids situations where there are multiple
fracture points between two inflection points

Additionally, we add a second check to ensure we don't hit spurious
blobs (all kinks should be symmetric and therefore be substantial in
each direction)

Seth Hillbrand 51b9d8e7ad Allow for rounding error in connection width checker
We perform checks using squared distance but this loses the integer
rounding in the standard norm.  To correct for this, we allow a single
IU in the restriction, allowing fractionally smaller connection widths
before calculating the squared limit

Jon Evans 39df5f3b15 Do not invalidate board caches during DRC
Footprints now modify their parent container when destroyed due to
26542796, and a temporary footprint is created during DRC
in some situations.  This can lead to board caches being messed
with during DRC which can cause unpredictable bad effects due to
multithreading.

Seth Hillbrand f56fcb0a14 Better handling of vertex sorting
Nominally, the zcode of a vertex is unique.  This is not 100% true,
however, as we must interlace two 32-bit numbers into a single 32-bit
number.  Sorting needs to account for the possibility that the zcode
will be the same while other elements of the vertex are different.  This
commit fixes the broken boolean logic to more clearly handle these cases

The connection width checker uses morton codes to order elements.  The

next/prev elements in the list.  Otherwise, hitting a fracture point
might make us skip in the wrong direction
