routing: - style(9) cleanup -- white space, braces, etc. - Make include guards consistent with our more general naming convention. - Rearrange and complete forward structure declarations in at_extern.h, remove testing of guards of various other include files to protect function declarations. This leaves an ifdef _KERNEL in at_var.h, but from inspection it seems likely that this file is not actually safe for inclusion in user space still. However, since it's not included from within src/ so this does not appear to be an issue (ifconfig, etc, have migrated to the generic cross-protocol ioctls for address operations).
