This fixes several touching-cases (clusters with uu not yet handled)

[traverse][fix] use two passes, in first pass avoid uu turns to get
...
the interior rings right at starting points. Second pass use uu, but
only switch source if there are only uu turns found. This fixes most
of the simple cases (complex cases can still go wrong)

[overlay] now we can/need to remove functionality to discard turns

colocated with uu and the same ring.
This breaks one case (# case_recursive_boxes_23) but repairs many (about 50%
of the wrong cases in robustness test)

[overlay] split polygon_count in left_count/right_count, this is necessary

for some cases (ex. #case_recursive_boxes_29). Also, necessary, now that
startable is defined, don't discard colocated cc in clusters, they are
sometimes necessary.

This has a small regression on 5 cases in multi_difference, to be inspected,

[overlay] stop discarding uu turns. Discard cc turns colocated with uu turns.
...
Including uu turns is necessary to handle cases as in #recursive_boxes_17 and also for
validity of output polygons.
This also makes code simpler for now, removing the separate uu handling from
for example select_rings
