Also, document in adjacent comments and in CODING_STYLE why we do that.

+- We never use the XDG version of basename(). glibc defines it in
+ libgen.h. The only reason to include that file is because dirname()
+ is needed. Everytime you need that please immediately undefine
+ basename(), and add a comment about it, so that no code ever ends up
+ using the XDG version!
