Fix and use __RENAME (and lose ___RENAME --- two underscores should be enough for anybody). This was the point of this change, because I want to use __RENAME to support the two basename variants and the two strerror_r variants. Lose a bunch of macros that weren't being used. Lose three dead files from the DNS code. Change-Id: I3ef645c566b16a52217bc2e68c7d54b37c7c9522
