Test incomplete objects

[naoliv]

We are adding some tests for incomplete objects in OSM (commonly included in OSM by new users):

*[area][eval(number_of_tags()) = 1],
*[lanes][eval(number_of_tags()) = 1],
*[maxspeed][eval(number_of_tags()) = 1],
*[name][eval(number_of_tags()) = 1],
*[oneway][eval(number_of_tags()) = 1],
*[ref][eval(number_of_tags()) = 1]
*[surface][eval(number_of_tags()) = 1] {
        throwWarning: tr("incomplete object: only {0}", "{0.key}");
}


*[name][area][eval(number_of_tags()) = 2],
*[name][ref][eval(number_of_tags()) = 2],
*[name][surface][eval(number_of_tags()) = 2] {
        throwWarning: tr("incomplete object: only {0} and {1}", "{0.key}", "{1.key}");
}

Is it interesting to include in JOSM? (with a better warning message, etc)

maxspeed already has a warning

only surface, is this really a common error case?

If I did it right, there are in Brazil:
21 ways and 120 nodes with surface only
6 ways and 163 nodes with surface + source
19 ways with surface + area

Let's not consider it common then.

I need to have some better sleep, time and everything else to make some stats for the rest.

But for sure we always see new users including:
area
name
name + area

Could the 3 at least (and for now) be considered?

lanes also has a test already.

In 8054/josm:

fix #11104 - add validator tests for incomplete objects (modified patch by naoliv)
