When removing items, we perform a two-pass removal, checking first
for the cached rectangle collision. Then, if we do not find the item
being removed, we perform a second, more expensive pass over the full
tree. This second pass is required as we cannot be certain that an
item's bbox has not been modified between insertion and deletion. In
which case, keeping stale pointers in the tree will lead to segfaults.

Changes SHAPE_CONVEX to SHAPE_SIMPLE to better reflect the limitations.
Changes SHAPE_LINE_CHAIN::PointInside calculation to allow points
strictly inside a line chain

There were two problems in the triangulation caching
of SHAPE_POLY_SET:
First there was a double free:
While SHAPE_POLY_SET implements the copy constructor,
it did not implement the operator=, which resulted
in the default operator= being generated by the
compiler. The default operator= copied the member
m_triangulatedPolys, which is a std::vector of pointers.
So after operator= execution, there are two SHAPE_POLY_SET
having pointers to the same TRIANGULATED_POLYGONs, each
of them deleting them in their destructors. This led
to segfaults, because calling
TransformShapeWithClearanceToPolygon on a Zone
uses operator= to copy the contained SHAPE_POLY_SET.
The new SHAPE_POLY_SET then went out of scope and
deleted the cached triangulation within the Zone.
This first problem is fixed by implementing operator=
for SHAPE_POLY_SET.
Second, there was a memory leak: Calling
"CacheTriangulation" on a SHAPE_POLY_SET,
then changing the polygon and then calling
"CacheTriangulation" again led to
leaking the
triangulations generated in the first call.
This second problem is fixed by holding
the cached triangulations in a unique_ptr.
SHAPE_POLY_SET: fix crash in VertexCount when it is a empty poly set, or when params are incorrect.
minor other fixes:
warning in degug mode in dialog_dxf_import_base.cpp
pcb_painter.cpp: remove a useless debug line.
The recent refactoring work to move zones from CPolyLine to
SHAPE_POLY_SET resulted in a reduction in pcbnew's python
capabilities. This change exposed SHAPE_POLY_SET to restore
that functionality (albeit with slightly different method names)
Removes the need of using the legacy code in polygon/PolyLine.{h,cpp},
refactoring all CPolyLine instances with SHAPE_POLY_SET instances.
The remaining legacy methods have been ported to SHAPE_POLY_SET;
mainly: Chamfer, Fillet, {,Un}Hatch.
The iteration over the polygon vertices have been simplified using the
family of ITERATOR classes.
