[OSM-dev] Request for Comments API URL

[Nick Hill]

The machine which serves www.openstreetmap.org has historically also served the 
API data.

There is no good reason for there to be such a hard link. On the contrary, the 
heavy server processes which are required to serve the API are probably wasted 
serving static data for the front web page and mapping view pages and limit the 
way we use www.openstreetmap.org domain name.

I therefore propose to set up a parallel API URL with the intention all API 
requests should migrate to that.
