Log: [libcasper] Update cap_dns API to not trigger unused variable warnings when disabled When compiling without casper these API calls result in unused variable warnings. Using #defines was lovely in the past but unfortunately it triggers warnings which can cascade into errors. Instead, just inline with some fallthrough functions and keep things happy.
