Documentation: Codify some guidelines for headers and chain-including

There has been some repeated discussion about how header includes should
be formatted, specifically on the topic of chain-including. The coding
style currently doesn't say anything about the topic but clearly people
have some basic assumptions. This patch tries to codify some common
ground rules that are supposed to reflect the existing practice.
