boundaries.osm - add Scotland and Flanders, Wallonia, Brussels

[westnordost]

Added subdivision Scotland (GB-SCT) and all subdivisions of Belgium - Flanders (BE-VLG), Wallonia (BE-WAL), Brussels (BE-BRU).

Guideline followed in terms of precision: Settlements and at least the more important roads must be on the right side of the border.

Rationale:

1. Scotland has some autonomy that leads to some rules and regulations being different from the rest of the United Kingdom that may be relevant to OpenStreetMap data. For example, the speed limits are different. (See ​https://wiki.openstreetmap.org/wiki/Default_speed_limits)

2. The languages spoken and official in Belgium are different depending on the subdivision. Dutch in Flanders (and Brussels), French in Wallonia (and Brussels). This is relevant for OpenStreetMap data, as in Brussels, (traffic) signs usually are multilingual while in Flanders and Wallonia, they are not.

3. The different regions in Belgium have some different rules and regulations. for example, the speed limits are different. (See ​https://wiki.openstreetmap.org/wiki/Default_speed_limits)

Motivation:

If you wonder why I contribute here at all, read on. (TLDR: boundaries.osm is being used by a couple more OSM-related projects to infer country-specific metadata):

The ​countryboundaries Java library uses this file as default input data. That library is at least used by StreetComplete and Vespucci to infer some country-specific metadata that helps users to input the correct data (maintained at github repo ​countrymetadata.
This is especially handy for things like displaying which languages for street sign names must/should be entered, e.g. in Brussels Dutch and French, but many other too (see ​officalLanguages.yml).

Additionally, this file is at least used by GraphHopper to also infer some country-specific metadata, such as speed limits.

Maybe specifically ​countryboundaries or ​countrymetadata would be interesting to you JOSM developers too, let me know.
