[Patch awaiting end of stabilization phase] Split Crossing Ways test into Crossing Ways and Crossing Waterways

[avarab@…]

Waterways should cross other ways (e.g. highways) without having connecting nodes. They should be left out of the crossing ways test.

Use layer! Waterway also can be on bridge or in tunnel.

When a waterway crosses a street on same layer something is wrong. Usually a bridge is missing. So this test is perfectly valid and data should be fixed.

Actually a layer=* is missing. It'll still flag it if there's a bridge and no layer=* tag on either objects.

In any case I'd like to reopen this as an enhancement request and ask that when ways are crossing and one of them is a waterway=* that it be reported under another category (Crossing Waterways).

Usually Crossing Ways that aren't waterways are errors in the data like a self-overlapping highway made from GPX data, or two residential streets that cross but don't share a node. Those errors are important and can screw up routing, but crossing waterways without a layer=* are something that's handled by all the renderers and no other user of the data really cares about.

Perhaps just a JOSM beginner question, but in the case where a road fords a waterway, would both be at the same "layer"? After all, the road traveler's (car, biker, walker, etc.) tires/ shoes/ feet "hit the road" at the same level as the water from the waterway. Is this a case where "a waterway crosses a street on the same layer" where something is not wrong? Should this produce an error? Or is there another way to represent a ford that should address this problem?

If the waterway and road meet with a ​highway=ford node then crossing ways won't complain. But if there's a highway=ford way over the waterway then the test will be triggered.

I'm attaching a test file which demonstrates this.
