Property is a pad info used mainly for fabrication or test.
Currently, supported properties are:
BGA property (variant of SMD pad)
Fiducial (global to the board or local to the footprint)
Test Point
Heat sink
Castellated.
And are used in Gerber files (copper layers and drill files)
Increment BOARD_FILE_VERSION to 20200104
Allows 0 to 4 chamfered corners, not only one.
A custom shape allow this kind of shape. However because it is a primitive,
it is easier to edit and it support thermal reliefs.
PAD_SHAPE_T and PAD_ATTR_T still have a double definition (new names and old names) to be sure python scripts are nor broken by the change.
PAD_DRILL_SHAPE_T does not have a double definition, because it is unlikely oblong holes are used in python scripts.
Double definitions will be removed in the (next) future.
Also add PAD_SHAPE_<PADSHAPE> equiv to PAD_<PADSHAPE> and PAD_ATTRIB_PAD_<PADATTRIB> equiv to PAD_<PADATTRIB>
(<PADSHAPE> = ROUND, RECT... and <PADATTRIB> =SMD, CONN ... )
