These objects can now be used in advanced DRC rules and
not just for keeping things out. Also remove the restriction
that at least one of the "basic" keepout rules must be set,
so that these areas can be used for more advanced rules.
Also fixes a bunch of naming issues, primarily with lowercase for
protected variables, but also some for consistency with other parts
of the code.
Also changes the zone fill radio buttons in Board Setup to be more
generic referring to legacy vs. current, and to have tooltips.
Fixes https://gitlab.com/kicad/code/kicad/issues/5583
This is a board file format change to account for the new properties.
Also, we now only store the critical information about the dimension's
geometry in the board, rather than storing every drawn line.
The DIMENSION object is now an abstract base, and ALIGNED_DIMENSION
is the implementation that exists today (we will add more dimension
types in the future)
