This maintains the primary goal of ensuring that bad splits do not allow
the triangulation process to continue. Instead, we boot this back up to
the top-level where we will simplify the polygon before triangulating
again.

- Avoid double-splitting a single point
- Check for mid-line intersections
- Avoid splitting zero-area polygons
- Keep full z-list for intersection checks

While ERROR_INSIDE was good for plotting, 3D generation, etc., it's
not good for generating router hulls.
Also reverts part of the change to always use polygons for PNS::SOLIDs. A single shape in a SHAPE_COMPOUND will be faster (and
more accurate).

Previously the snap points computed for oval pads didn't get all the
points correct. This breaks out the "find snap points for ovals"
into a function, reworks the logic, adds some tests.
Also adds "extremum points" when the oval isn't exactly H/V.

Using the new ITEM_MODIFICATION_ROUTINE system, drop in two new
tools: chamfer and line extend. These are two geometric operations
that are relatively common when editing footprints in particular.
Chamfer delegates the geometric calculations to a dedicated unit
in kimath/geometry.
Its members can be on copper layers, but the group itself isn't on any
layer.
Also fixes a bug where we were trying to clone TRIANGULATED_POLYGON::TRI
shapes as indexable sub-shapes. (The TRI only has indexes into its
parent, so cloning it will only result in segfaults down the line.)
Also fixes a bug where we weren't including copper items inside groups
when checking footprint net ties.

1) Also reorders parameters to make sure the compiler helps out.
2) This also makes it harder to mess up the discrepency between
BOX2I/wxRECT/etc::Inflate() and SHAPE_POLY_SET::Inflate.
3) Also fixes a couple of bugs where the corner strategy was passed
in as a segCount.
4) Also fixes a couple of bugs where the error wasn't forced to the
outside to match the ERROR_LOCATION.
5) Also fixes a couple of bugs where the seg count was specified
without regard to an already passed-in max deviation
1) Don't fracture font glyphs when generating them; we're going
to fracture during triangulation anyway.
2) Don't check for self-intersection when deciding to fracture.
It costs nearly as much as the fracture does.
3) Cache drawing sheet text.
4) Use the current font when checking for cache validity.
5) Parallelize glyph triangulation.
6) Don't invalidate bounding box caches when offset by {0,0}
7) Use the glyph cache when generating text effective shape.
8) Short-circuit NormalizeJustification() if its center/center.
9) Don't triangulate for GuessSelectionCandidates()
10) Avoid sqrt whenever possible.
11) Pre-allocate bezier and SHAPE_LINE_CHAIN buffers.
