warnings: fix "iteration XY invokes undefined behavior" warnings

These were caused by loops which caused overflow of variables of type
angle_t (= unsigned) by multiplication with iterators of typed int in
angle calculations. Changing the type of the iterator variables to
"unsigned int" prevents the undefined behavior.
