Clipper might mess up the rotation of the indices such that an arc can be split between
the end point and wrap around to the start point. Detect if this happened and fix it as
required.
Also, handle arcs at the last segment of the chain correctly, meaning we can have arcs
towards the end of the chain that finish at the starting point of the chain.

This ensures that the arc shapes remain correct after removing
a point belonging to an arc or inserting a point in the middle
of an arc.
Simplify implementation of Replace( ..., aP ). Now a Remove
operation followed by an Insert operation.
Improve QA test for SHAPE_LINE_CHAIN Append, Insert and Replace
Implement SHAPE_LINE_CHAIN::splitArc to break up an arc into two
Implement SHAPE_ARC::ConstructFromStartEndCenter and add qa test
m_shapes now has two possible indices. The first one is populated if
the point is associated with an arc and the second index is populated
if the point is shared between two arcs.
Creates new substructure for arc management. Existing functions provide
wrapper to use SHAPE_LINE_CHAIN as normal, without arcs while also
permitting the addition of arcs into the chain
The new line collision search uses BBox() to check for colliding
objects. BBox in the SHAPE_LINE_CHAIN did not include width as the
chains were assumed to be zero-width. This is not the case for
PNS::LINE elements.
We mostly don't notice this because DRC checks for SEGMENT collisions
but it becomes obvious/annoying when we cannot place a track for unknown
reasons and the snap-back doesn't take line width into account.
Fixes#3776 | https://gitlab.com/kicad/code/kicad/issues/3776
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
