Arcs can be altered by the process of changing from on-disk
representation to in-memory representation. Saving back to disk without
modifying the arc should not modify the calculated values.
This stores a copy of the on-disk representation that is only used to
save back to disk in the event that the arc is not modified during
editing.

(cherry picked from commit cd7141fd10)
Rather than skipping our endEdit() call in libedit, we need to
parameterize whether we want the shape open/closed. Closed will remove
the last segment if it lands on the first point. We don't want that
but we do want to remove the last point if it duplicates the second to
last (in the case of double-clicking)

We no longer have any knowledge of the original start/end of the arc,
since SetArcAngleAndEnd swaps the start and end to ensure the arc is
always clockwise at the end.
Adds a method EDA_SHAPE::EndsSwapped() to notify whether the start/end
point of the shape were swapped.
