The geometry and numbering logic is separate to the dialog, and
can be separated for clearer logic and better testability.
Moreover, refactor it to avoid any dependency on pcbnew
classes, so it can be move to common for potential re-use in
eeschema and friends in future.
Also convert all wxPoint logic in these classes to VECTOR2I and
fix some function visibilities.
Add some unit tests of the ARRAY_OPTIONS geometry and numbering.
* No initial copied object changed (this was a serious bug to modify these objects. Previous version modified references and other texts using a very stupid algorithm).
It also fixes bug 1549231
* only new pads are numbered (therefore renumbering is used only in footprint editor)
* remove not working and useless feature in circular array: now only use number for pads (others options using alphabetical letters are removed: did not work corectly, and were useless)
* a more clear option is used to choose if the pads are numbered from a choosen value, or from the first avaible value
* Adding a warning messsage if a parameter is incorrect.
Text arrays can now use "%s" as a placeholder to be substituted with the array index.
Also expand menu options for move exact, arrays and duplicate.
Minor fixes for arrays - use proper unit parsing, add numbering start for circular arrays
Add circle radius indicator to array dialogue
