The old item pointers (which aren't safe to keep around) were
removed in favour of opaque references (void*) which are then
compared against existing items when needed.
Also improves brightening by brightening the whole footprint
(ie: its pads, drawings, reference and value) rather than just
its target cross.
(cherry picked from commit 30e90b0)
It was broken by commit c78171d01f.
During creation, the Drc must only display a error message, and do not create markers.
Markers are created only during a full board DRC test.
commit c78171d01f replaced this behavior by a incorrect one (create markers and do not show error messages)
It looks like D_GLIBCXX_ASSERTIONS=ON activated on some Linux versions creates too zealous tests at run time.
This patch just calculate the same pointer value using a slightly different formula.
Fix also a hard-to-understand comment

Make refilling zones during DRC optional to prevent the board from being
changed by changes in the polygon filling. Default to off to prevent
changes by default.
