Is some cases a created pad stack name had the same name as an other pad stack
having a slightly different shape, thus creating pads with a incorrect shape on board.

This fixes some DXFs imports where unforunately CAD tools like SolidWorks
randomly decide to mirror circle definitions across the "z" axis (resulting in x or y axis flips in 2d)
Most likely live projection from 3D to 2D drawings introduces this.
However this is DXF specification to describe it so obtusely with vectors for a 2d drawing.
For round rect pads, when the arc error was OUTSIDE, the shape was too big and creates
bad shape for chamfered round rect pads.
For chamfered pads, when the clearance value was not 0, the chamfer was not at the
right place.
Start, mid and end are the "real" properties and come with less
error.
Also collapses two arc polygonization routines into one.
Also fixes DRC checks to be cognizant of arc approximation error.

1) Tests can't expect accuracies around 1 to work. PCBNew defaults
to 5000.
2) Tests shouldn't artifically expand tolerance just to match the
results.
3) Tests should guarantee that end point is on arc, not just close
to it.
4) Standard polygonization of a circle is inside so splitting the
error needs to increase radius, not decrease.
5) Special-case first and last points so that they're exact.
The snap obeys only the Ctrl key and not the global preference setting
for drawsegments because rectangles are _always_ on H/V lines when drawn

Previously, SHAPE_POLY_SET::CacheTriangulation() was able to handle polygons
with holes.
Due to recent changes, CacheTriangulation( true ) handle polygons with holes,
but CacheTriangulation( false ) did not handle polygons with holes, due to a
missing call to Fracture(), lost in latest changes.
This is now fixed.

1) For a while now we've been using a calculated seg count from a given
maxError, and a correction factor to push the radius out so that all
the error is outside the arc/circle. However, the second calculation
(which pre-dates the first) is pretty much just the inverse of the first
(and yields nothing more than maxError back). This is particularly
sub-optimal given the cost of trig functions.
2) There are a lot of old optimizations to reduce segcounts in certain
situations, someting that our error-based calculation compensates for
anyway. (Smaller radii need fewer segments to meet the maxError
condition.) But perhaps more importantly we now surface maxError in the
UI and we don't really want to call it "Max deviation except when it's
not".
3) We were also clamping the segCount twice: once in the calculation
routine and once in most of it's callers. Furthermore, the caller
clamping was inconsistent (both in being done and in the clamping
value). We now clamp only in the calculation routine.
4) There's no reason to use the correction factors in the 3Dviewer;
it's just a visualization and whether the polygonization error is
inside or outside the shape isn't really material.
5) The arc-correction-disabling stuff (used for solder mask layer) was
somewhat fragile in that it depended on the caller to turn it back on
afterwards. It's now only exposed as a RAII object which automatically
cleans up when it goes out of scope.
6) There were also bugs in a couple of the polygonization routines where
we'd accumulate round-off error in adding up the segments and end up with
an overly long last segment (which of course would voilate the error
max). This was the cause of the linked bug and also some issues with vias
that we had fudged in the past with extra clearance.

Partititioning small polygons causes excessive partitions when we use a
fixed number of cells per side. Partitioning by size keeps the
partition count limited and speeds the calculations.
Also adds an option to not partition the grid for elements (like 3d
raytracing) that do not need it.
Fixes https://gitlab.com/kicad/code/kicad/issues/5579
When loading footprints, we need to skip the triangulation trigger in
rotate. If the triangulation cache is invalid when starting the
rotation, do not retriangulate after the rotation.
The use of printf, wxLogDebug, and std::err/std::out causes excessive
debugging output which makes finding specific debugging messages more
difficult than it needs to be.
There is still some debugging output in test code that really needs to
be moved into a unit test.
Add debugging output section to the coding policy regarding debugging
output.
